Frequently asked questions
The Land Transport Authority (LTA) and the Economic Development Board (EDB), which co-chair the Electro-Mobility Singapore (EMS) taskforce, have announced that Type 2 AC and Combo-2 DC charging systems will be adopted as the National Public Charging Standards (NPCS) for EVs. As our chargers comply with the NPCS, they will be able to accommodate all types of EVs sold in Singapore.
It is generally not recommended, but please refer to your vehicle manufacturer’s recommendation on the best practices for charging your electric vehicle.
Our app will show the comprehensive list of our charging locations. The list will be updated regularly as Volt’s charging network expands.
- Please remove your vehicle from the charging station within 20 minutes after charging, to allow other EV users to enjoy our charging services.
- Properly coil the charging cable neatly around the designated cable winding trough or bracket and insert the charging gun into its dock after usage.
- Note that some of our chargers may require you to press the unlock button on the charger to release the charging gun. As such, please refrain from forcefully pulling the mechanically locked charging gun out of its dock.
- In case of emergency, please press the emergency stop button immediately.
- Based on SCDF regulation, the safety e-stop should be 3-15m away from charger.
- Plug the charging gun into your EV charging port. Depending on the type of charger, you may be required to press an “unlock” button on the charger to release the charging gun.
- To activate the charger, use the Volt EV Charging App to scan the QR code on the charger or key in the ID number indicated on the charger.
- From the app’s charging menu, select “start charging”.
- Enjoy the charging process! Monitor how much energy (kWh) has been supplied to your EV, the charging cost ($) and the duration of the charge through the app.
- Select “end charging” once you wish to terminate the charging process. When your EV is fully charged, charging will be automatically terminated, and you will be notified via the app.
- On the app, you will be presented with your order details. Click “proceed to payment” to pay via your linked debit or credit card.
- Do remember to unplug the charger from your EV, return the charging gun to its designated dock and exit the lot so that other EV users may use the charging station.
Yes, an in-app notification will be sent to notify you that charging has completed.
There is a grace period of 20 minutes after your charging ends. Let’s be gracious to other EV drivers!
Unless under maintenance, our public chargers are operational 24/7, subject to the operating hours of the car park they are in.
Reservations are not available at the moment. Chargers are available on a first come, first served basis. You can find available chargers in real time via the Volt EV Charging App.
Some EVs are designed to automatically stop or slow down charging before the battery is fully charged to protect the battery lifespan. Please refer to your vehicle manufacturer’s manual for more details.
Yes! All public EV chargers in Singapore must comply with the stringent safety precautions and requirements as required by TR25, which includes regular preventive maintenance.
Our chargers are equipped with various levels of safety protection as well as an emergency stop button. They are also certified for protection level ratings of IP55, IP54 and IK10, making them suitable for use even in wet weather.
There could be various reasons, but the most common causes are:
- Disruption in the building’s power supply
- Hardware disruption (e.g. charging gun was removed)
- A technical fault with the EV or charger
To restart charging, perform the following steps:
- Unplug and reinsert the charging gun into your EV.
- Activate a new charging session via the app.
There are generally 5 main factors that can affect an EV’s charging duration:
- EV battery capacity: EVs with larger battery capacity (measured in kWh), will require a longer charging time compared to EVs with smaller battery capacities.
- State of charge: If you are charging your EV from a lower state of charge, say 20%, it will take longer to reach a full charge than if you are topping up from 50%.
- EV charger rating: The charging duration is affected by the output power of the charger you are using. For example, your EV will charge faster when using a 22kW charger compared to a 7kW charger.
- Maximum charging rate of the EV: You can only charge an EV’s battery at the maximum charge rate that the vehicle’s on-board charger can accept. For example, while it is perfectly safe to use a 22kW EV charger on an EV with a maximum charge rate of 7kW, the EV won’t be able to charge any faster than if it were connected to a 7kW EV charger.
- Environmental factors: A lower ambient temperature may increase the charging duration, particularly when using a rapid charger. Fortunately for us in tropical Singapore, this is unlikely to affect us.
Generally speaking, the higher the power rating of the charger, the shorter the charging time. However, the actual charging time depends on the EV’s battery size, on-board charger capacity and compatibility with chargers (AC or DC). Please refer to your vehicle manufacturer’s manual for more details.

For any emergency or safety violation, you may reach out to the security or property management team for immediate assistance.
There are various reasons why you may be unable to start charging. Here are some of the more common causes and solutions:
- Poor internet connection: Please ensure that your mobile phone has an active and stable internet connection and try again.
- Unable to scan QR code: Please try the following steps.
- Ensure a well-lit environment and that the scanner is properly focused on the QR code when scanning.
- Check that the QR code is not scratched, defaced or damaged. If it is, please send us a fault report via email at firstname.lastname@example.org
- Key in the charger ID instead of using the QR code.
- Unsettled payments with Volt: You will not be able to start a new charging session until you have settled the payments for your previous session. Please make payment via the app and try again.
- Outdated app: Check if you are using the latest version of the Volt EV Charging App.
- Charging gun is not properly connected: Please ensure that the charging gun has been properly inserted into your EV and try again.
If you still experience problems, please email us at email@example.com.
Some EVs may be designed with a mechanical lock system to secure the charging gun to the EV. Please check if the mechanical lock has been disabled prior to removing the charging gun. Please contact your EV manufacturer for more advice regarding the mechanical lock.
Fees and Billing
Our fees are charged on a pay-per-use model, based on an SGD per kilowatt-hour (SGD/kWh) rate. The kWh unit measures the amount of electrical energy supplied to charge your EV and is derived from electrical power (kW) multiplied by the amount of time (hours) the power is supplied.
Our charging rate varies for different chargers and locations. Please refer to the Volt EV Charging app for a comprehensive list of charging rates.
You can view your past transaction statements on the Volt EV Charging App. You may also opt to receive your transaction statement via email after each charging session.
