How many types of chargers are there? How many slow, medium and quick speed chargers are available?

There are currently 1168 EV chargers located in public car parks and streets across Macau, supporting national, European and Japanese standards (as of 13 January 2023). There are 131 quick chargers, 11 medium-speed chargers and 1026 slow chargers.

What do the different colors of indicator lights on the quick chargers (Brand: Efacec & Setec Power) mean?

The colors of the indicator lights on the charging station represent the following different situations:

  • Green: The charging station is in normal condition and ready for charging
  • Red: The “Emergency” button has been pressed or the charging station is out of order
  • Blue: Charging in progress
  • Flashing blue: The charging plug is connecting to the EV (only applicable to IEC and CCS plugs, CHAdeMO does not have this display)

Can the 3 charging plugs of the quick charger be used at the same time?

There are 3 charging plugs on the quick charger to serve the needs of different EV charging systems, they are CCS2 (direct current), CHAdeMO (direct current) and IEC Type 2 (alternating current). Most of CEM's quick chargers can only support charging 1 EV at a time, while some chargers can support either one of the DC charging (CCS2 or CHAdeMO) and AC charging (IEC Type 2) simultaneously. If it is displayed on the CEM app that the charger can be used for two parking spaces, it means that two EVs can be charged at the same time.

What should I be aware of when start charging an electric vehicle (EV)?

a)  Mobile has good signal reception

b)  Choose a suitable charging plug

c)  Ensure the EV is turned off and doors are closed

d)  Ensure proper connection between charging cable and EV

e)  Confirm the EV has successfully started charging before leaving

The status “Charging” is displayed on my mobile, but why is the charging process interrupted after a while?

During the charging process, the charging station and the EV will communicate constantly. If the communication of either party is disturbed or interrupted, charging service will be interrupted. Customers need to unplug and re-start the charging process.

Meanwhile, when the EV is being charged to over 80% capacity, the charging rate will slow down automatically. If the maximum charging unit of this charging is reached (the factory pre-set level is usually 80%, while some are 50%, it varies according to EV models), the EV will stop receiving high current electricity inflows, thus a rejection notice will be sent to the charging station.

How to stop charging? What should I be aware of?

You can stop charging via CEM mobile app or the link in CEM WeChat’s push notification. When charging is completed, please put the plug back to its holder and put the cables with care.

Caution: Do not unplug the charging plug during the charging process. If you want to stop charging, please follow the procedures of "Stop Charging".

The charging cable cannot be unplugged when charging is complete. What should I do?

Please make sure you follow the "Stop Charging" procedures first, and unplug the cable; or use the vehicle side control switch to unlock.

During the charging process, is the EV still charging if the charging station is found to be offline and “No relevant information” is displayed in mobile app? How do I stop charging?

In this case, the charging is still being carried out normally. However, the charging data cannot be updated in real time. The relevant data will be updated immediately after the charging station is online. If you need to stop charging when the charging station is offline, please call CEM Info Lineat 2833 9911.

What does the “Emergency” button on the charging station do?

The “Emergency” button is only for terminating charging when there is an emergency. Do not press this button unless it is an emergency.

Why is the charging speed lower than the output level of the charging station?

Charging speed is not only related to rated output of the charger and the battery status of the EV, it is also closely related to the battery management system (BMS) and the on-board charger (OBC) of the EV. The maximum power that can be received by the on-board chargers of different brands of EVs is different. It is recommended that users read the operation manual of the EV or check with the car manufacturer to avoid the failure to achieve fast charging when using quick chargers.

Which is better, quick or slow speed charging?

Generally speaking, quick charging refers to charging an EV with direct current, and it can charge 80% of the battery within 1.5 hours. Slow charging refers to charging with alternating current and it takes several hours to charge. Since the output current is large, quick charging saves time, but it can easily increase the heat of the battery which might decrease the battery capacity in the long run. The battery management system (BMS) in the car will automatically adjust the charging current according to the condition of its own battery, which can minimize the impact of quick charging.

Who is responsible if there is an accident or the device is damaged during charging? Is there a compensation mechanism if the vehicle is affected and damaged?

Self-charging stations provided by CEM in designated car parks operate on a highly stable and reliable network. Under no circumstances will CEM be liable for any losses incurred by the users arising from or related to the use of EV charging stations. If, due to the incorrect use of the EV charging station by the users, actions are brought or compensation demanded by third parties, users are solely responsible and shall indemnify CEM for all damages.

What should I do if I lose my phone and cannot stop charging?

For any emergencies, please call CEM’s Emergency Service at 2833 9922.

Can I stop charging via CEM WeChat if the charging was started in CEM App?

Yes. First, please make sure that the account bound to WeChat is the same as the account being used for charging. Then, follow the steps below to stop charging via CEM WeChat:

     Step 1)   Open CEM WeChat

     Step 2)   Click “About CEM”

     Step 3)   Click “Electric Vehicle”

     Step 4)   Click “Check charging status/Stop Charging”

     Step 5)   Click “Stop charging”

Do I have to bind my account to CEM WeChat for charging? How to bind?

Yes, your account must be bound to CEM WeChat before charging. Please follow CEM WeChat and bind your account via one of the following methods:

a)  On-site binding:

Scan the QR code on charging station with WeChat scanner, and input your e-Service account’s username and password according to the indications, then press “Bind” to complete binding to start charging.

 b)  Advanced binding

      Step 1)  Open CEM WeChat

      Step 2)  Click “Service”

      Step 3)  Click “My Service Account”

      Step 4)  Click “Binding management”

      Step 5)  Input your e-Service account’s username and password, then click  “Bind”.

An e-Service account may have multiple EV contracts registered. Can I login the same account with different mobiles to charge different EVs at the same time?

Yes, but you need to pay attention to the stability of the app. If more than one person logins the same account with different devices at the same time, it may lead to instability of the app.

How can I pay for the charging fee?

You can top up the wallet in CEM App and the charging fee will be deducted from the balance, or use an UnionPay Credit Card for one-time payment.

What are the available top-up channels?

You can top up the wallet in CEM App through MPay, BOC Pay and ICBC ePay. You can also visit our Customer Service Centres for cash top up.

Are there any other third-party top-up channels?

You can also top up through MPay and BNU mobile banking apps.

Is there any upper limit for the wallet balance?

Yes, the upper limit for wallet balance is MOP 2,500.

Is there a minimum balance required to start charging? If there is an insufficient wallet balance, can I still start charging?

The minimum wallet balance required to start charging is MOP 30, and charging will stop automatically when the balance is used up. If the wallet balance is below MOP 30, you need to top up first to restart charging, or use an UnionPay Credit Card for one-time payment.

Can the wallet balance be refunded?

To terminate the use of the wallet, you can visit CEM to apply for cancellation and balance refund.

Can I top up via “Electronic Consumption Benefit Scheme”?

Topping up wallet via “Electronic Consumption Benefits” is not supported. Using “Electronic Consumption Benefits” to pay electricity bills is subject to relevant regulations, i.e. can only be used to purchase goods or services and cannot be exchanged for cash in any ways. Since the user can apply for a balance refund after canceling the wallet, which does not comply with the abovementioned regulation, thus topping up wallet through “Electronic Consumption Benefits” is not accepted.

How to use UnionPay Credit Card to pay for the charging fee?

First, you need to complete the UnionPay payment verification in CEM App, then we will pre-authorize MOP 800 from the UnionPay credit card. Upon completion of charging, only the actual charging fee will be charged.

What is Tariff Clause Adjustment (TCA)?

TCA is set according to the cost of heavy fuel, natural gas and electricity importation of last quarter and is charged based on consumption. The adjustment is fixed quarterly.

What is the difference in charging time and charging fee at different charging speeds?

Generally, the battery capacity of electric vehicles (EVs) on the market is about 80 kWh. If it is charged from a remaining power level of 20% to 80%, 48 kWh is required to be charged. The following are the costs at different charging speeds and time periods. No matter which one is selected, it is cheaper than fuel.


Is it cheaper to drive an EV than a fuel vehicle?

Taking every 100 kilometers driven as an example, the fuel consumption of a fuel vehicle is about 11.1 liters, while the power consumption of an EV is about 20 kWh. Based on the oil price of MOP 13.32/liter in June 2022 (including discounts), the fuel cost is about MOP 148. Driving an EV is about 37%~82% cheaper than a fuel vehicle:

Does billing stop automatically when fully charged?

Charging and billing will automatically stop in the following situations: 1) The charging device receives a stop signal from the fully charged EV; 2) When the wallet balance is used up.

Some EVs will slow down the charging after being charged to 80%, how is this period billed?

Public and general charging tariffs are charged based on the charging consumption, the billing will not be affected.

Is the charging fee calculated according to the actual charging power?

Charging fee is calculated according to the rated output power of the selected charging facilities and the actual charging consumption during the tariff period. The actual charging power only reflects the input power that the EV can receive at that moment.

How will the fee be calculated when it is found that there is no electricity received after charging for a while?

If there is no electricity received by the EV, no consumption will be recorded, so it will not be billed.

Plug Type

For the plug CHAdeMO, it is a DC plug and mainly designed for the Japanese electric vehicle.

For the plug CCS/Combo-2, it is a DC plug and mainly designed for the European electric vehicle.

For IEC 62196 Type-2, there are AC socket and AC plug.

1.  For an AC socket, all the electric vehicles can be charged with their own appropriate charging cable. For example for European vehicle with an IEC Type 2 – Type 2 charging cable, or a Japanese vehicle with an IEC Type 2 – Type 1 (SAE J1772) charging cable.

2.  For an AC plug, all the electric vehicles which have the appropriate socket can be charged with this plug.

Aside from buying & maintenance cost, also need to consider:

1. charging speed --> as it will affect your routine charging plan

2. battery size --> as it determines how far you can drive after 1 full charge

3. driving cost --> kWh per km

Use Appropriate Charger

Quick Chargers can provide 3 phases AC supply for Type 2 Plugs. Since IEC62196 Type-2 AC plug can be 1 phase or 3 phases, some EV equips with a 1 phase on-board AC-DC converter still can connect with the Quick Charger AC Plugs, however the consumed power will be limited by the EV itself through the BMS.

If using Quick Charger, please use the fastest charging plugs that your vehicle can handle, for example for European vehicle with a DC CCS2 combo, a Japanese vehicle with a DC CHAdeMO, and for some other which the vehicle equipped with 3 phases on-board AC-DC converter can use 3 phases Type 2 Plugs.

ECO Mode

ECO mode is better suited for city driving due to frequent stops and accelerations. Rapid acceleration will waste more energy hence shorten the driving range. Eco Mode will provide smooth acceleration and longer range.

B Mode

For better Energy Efficiency, B Mode can recover energy during braking ( deceleration, especially downhill ) in order to gain longer driving range.

Public charging stations to rise to 2,000 by year-end -CEM

Source: Macao Daily News

Release Date: 2 November 2022

Yuki Lei Taipa and Coloane Community Service Consultative Council member Leong Chon Kit yesterday quoted power utility CEM representatives as saying that the total number of public charging stations for electric vehicles will increase from 495 to 2,000 by the end of this year, adding that the charging points are mainly in the city's public car parks run by the Transport Bureau (DSAT) and Municipal Affairs Bureau (IAM).

Leong made the remarks during a press briefing after the government-appointed council's regular closed-door meeting with CEM representatives at the Seac Pai Van Community Integrated Building in Coloane yesterday.

Leong noted that most of the 2,000 charging stations will be slow charging, adding that most vehicle owners had switched to slow charging since charging for electric vehicles came into effect in July, which has exceeded demand for fast charging.

According to the representative, the Environmental Protection Bureau (DSPA) has recently issued guidelines on applications for charging stations in private car parks, Leong said, noting that as of Sunday, CEM had received 208 applications, of which 155 had already installed electricity meters at their respective car parks.

Leong pointed out that among the 495 existing charging stations, 74 percent were installed in the Macau peninsula, while Taipa and Coloane accounted for 17 percent and 9 percent respectively.

200 public charging stations outlined in the Five-Year Plan have been in place

Source:  Gabinete para o Desenvolvimento do Sector Energético (GDSE)

Release Date: 3 November 2020 

Macao SAR Government has installed all of the 200 public EV charging stations in accordance with the Five-Year Development Plan of the Macao SAR (2016-2020), which should be able to satisfy the demand for mid-journey charging in the short to medium term. In the long run, the government will decide if more public electric charging stations are to be built upon review. Among the 200 public EV charging stations, 133 are located at the Macau Peninsula, 46 at Taipa and 21 at Coloane. Moreover, two charging stations for motorcycles have been installed at the Macau Peninsula. For more information, please refer to https://www.gdse.gov.mo/public/chn/EV/ev.html.

To address the long-term demand for EV charging, the government put forward a policy with the guiding principle of “self-use charging facilities for daily use and public charging as supplementary”. Fees will be imposed for using public EV charging facilities and the fee will be higher than that of private stations to encourage installation of medium/slow chargers at residential parking spaces. 

The related government departments will continue with the introduction and promotion of EVs according to the Five-Year Plan. Specific measures include improving the charging facilities, putting in place convenient measures and encouraging public sectors to use environmentally friendly vehicles. The government has waived motor vehicle tax for EVs to encourage citizens to opt for EVs when they plan for a car purchase.

Macau's eco-friendly energy vehicle population reaches 4,706 in Q3, including about 1,100 electric vehicles (EVs)

ource: Plataforma Media

Release Date: 3rd November 2020

As of the third quarter of 2020, there are 4,706 eco-friendly energy vehicles in use in Macau, which include 1,126 EVs, 3,392 hybrid vehicles and 188 natural gas vehicles, according to the Transport Bureau (DSAT).

DSAT said in a reply to media inquiry that, the SAR government is using 61 new energy vehicles in its official fleet, while gaming operators are running 189 new energy buses.

DSAT added that the plan of introducing 150 electric taxis in 2019, as stated by Transport Bureau Director Lam Hin San, will be deferred because market demand and operating environment has been impacted by the pandemic.

Separately, the new bus concession contract has stipulated that at least 50% of the operating buses and extra-large buses not passing Governor Nobre de Carvalho Bridge have to be replaced by eco-friendly energy vehicles by 1 January 2022 or earlier; and all operating buses and extra-large buses shall be replaced by eco-friendly energy vehicles by 1 August 2024 or earlier. DSAT will provide necessary support to bus companies in due course, such as expediting the administrative approval process, providing flexible vehicle examination schedules, among others.

More information on charging fees

Source:  Gabinete para o Desenvolvimento do Sector Energético (GDSE)

Release Date: 3 September 2020 

Office for the Development of Energy Sector of Macau previously issued a press release explaining the government’s policies and measures to promote “self-use charging facilities for daily use and public charging as supplementary”. The government has started with installing 200 public charging spots for public use and meanwhile explained the benefits of installing medium/low-speed chargers at private parking spaces to encourage daily charging with self-use charging facilities.

The press release also mentioned that fees will be charged for using public EV charging stations, arousing citizens’ concern. As for the pricing approach, the government considers that the fees for private charging should be lower than that of public charging stations, with the purpose to incentivizing residents to install low/medium-speed charging equipment in their private parking places.     

In addition to the installation and maintenance costs, the power consumption is another factor that explains the fee imposition for public charging facilities to ensure long-term operation. For example, the government is considering setting the fee for public fast charger at a level higher than household electricity fee but lower than fuel cost per kilometer. The Office for the Development of Energy Sector of Macau is studying the fee levels and will announce the details in due course.

Private installation of medium/slow chargers has multiple benefits

Source:  Gabinete para o Desenvolvimento do Sector Energético (GDSE)

Release Date: 30 July 2020 

To build a green tourism city, air quality must be improved from different aspects. As part of Macau's air pollutants comes from vehicle exhaust emissions, the government is actively promoting the use of eco-friendly vehicles, with EVs in the spotlight. With the technological progress and mass production of EVs, more models are available for selection and their prices may drop to the levels close to traditional fuel vehicles, making them popular among more users.

In order to further promote the use of EVs, the government would work with the public to make “private charging facilities for daily use and public charging as supplementary” happen. The government will first build public charging points for journey pit-stops, while the public are encouraged to install their own chargers at private parking spaces for daily battery top-up.

Of the 200 public charging parking spaces first proposed by the government in the "Five-Year Development Plan (2016-2020)", 196 have been in place, covering 42 public parking lots under the jurisdiction of the DSAT (with a coverage rate of 80%) ) and six parking spaces on public road (commonly known as "metre parking spaces"); the installation of the remaining four chargers at a metre parking space area has been sped up to go along with the road works in the respective area. These 200 public charging spaces will answer the needs for mid-journey charging in the medium to long run in Macau.

In terms of convenience and economic benefits, citizens are advised to install their own chargers at private parking spaces for daily use and charge up the battery at night. Quick chargers incur higher installation costs and may shorten the battery life as well as waste grid resources. Meanwhile, the fee for public charging will be imposed, and new fee for private charging will be cheaper than that of public charging. Therefore, citizens are encouraged to install self-use slow and medium chargers at residential parking spaces, which will be more convenient and economical.  Besides, charging EV batteries with slow/medium chargers in the night time can extend battery life, improve grid efficiency, as well as protect the environment.

At present, the Law No. 14/2017 allows minority owners to carry out electric engineering works in common parts of the building by posting notices of works to simplify the installation procedures. Moreover, CEM can also provide advice on electric wiring to the applicants. Residents living in the same building can collaborate to install private chargers in order to facilitate installation and share the cost. Coordination between residents and property management offices or committees are encouraged to facilitate installation. The government would direct CEM to provide full support in this regard. 

With medium/slow chargers at private parking spaces, users enjoy multiple benefits:

  1. charging EV battery anytime;
  2. slowing the ageing of EV batteries and extending their service life to save money;
  3. spending less on facilities, installation, electricity and electrical work compared to fast chargers;
  4. improving grid efficiency and protecting environment through night-time charging; and
  5. more convenient and cost-effective compared to public chargers, which will incur higher fees.
