Understanding the safety standards and certifications behind an EV charger is a great first step towards choosing the right charging solution. As a high-powered electrical device that can remain in operation for several hours at a time, an EV charger should be designed and tested to reduce the risk of electrical faults and ensure reliable long-term performance. While safety is one of the most important considerations, it should also be evaluated alongside factors such as charging requirements, installation environment and long-term suitability.

How does Safety Certification Work?

Before an EV charger reaches the market, manufacturers must demonstrate that it meets relevant safety and technical requirements. Depending on the certification or regulatory scheme, this may involve laboratory testing, factory inspections, technical documentation, or assessments by accredited third-party organisations. Some requirements rely on independent certification, while others, such as CE marking, are based on the manufacturer’s declaration that the product complies with applicable legislation.

Common Safety Certificates or Marks

IEC compliance means that an EV charger has been designed and tested in accordance with internationally recognised standards developed by the International Electrotechnical Commission (IEC). These standards help define how the charger should perform electrically, how it should respond during normal charging, and how it should protect users and connected systems. Some of the most common IEC standards you’ll encounter include:

• IEC 61851 – Covers the general requirements and safety of conductive EV charging systems.
• IEC 62196 – Defines charging connectors, plugs and sockets to ensure compatibility and safety.

As for the CE mark, this is a manufacturer’s declaration that the product complies with applicable European legislation. They must evaluate the product against relevant legal requirements, prepare detailed technical documentation, carry out the necessary assessments, and retain evidence to demonstrate compliance. Incorrectly applying the CE mark can result in regulatory action, making it a legally accountable declaration.

Some manufacturers also choose to have their products independently tested by recognised certification bodies including but not limited to TÜV, UL, and CB. These organisations assess the charger against relevant standards, providing an additional level of confidence that the product has been evaluated by an impartial third party. When comparing similar chargers from different brands, independent certifications can provide another point of reference for your choice of product.

Additional Requirements in Singapore

Specifically in Singapore, EV chargers require an additional type approval issued by the Singapore Land Transport Authority. EV chargers used to charge electric vehicles in Singapore must be approved before they can be supplied, installed, or certified, and they must comply with TR25:2022, TR25:2022 + A1:2025 or SS 722 for type approval.

These checks are not just an additional stringent layer of safety but are mandatory and part of being a lawful deployment.

Once approved, each charger model receives a type approval label that identifies it as meeting Singapore’s regulatory requirements. This allows installers, regulators and customers to verify that the charger has been approved for use locally.

Protection Ratings and Safety Features

Since many EV chargers in Singapore are installed outdoors, they need to withstand rain, humidity, dust and accidental impacts. Protection ratings such as IP55 and IK10 indicate how well a charger can resist these environmental conditions, helping to protect its internal components and maintain reliable operation over time.

Other built-in safety features of an EV charger can include:

• Residual current protection (RCD): Detects leakage currents and cuts power to reduce the risk of electric shock
• Overload protection: Disconnects power if excessive current is detected
• Short-circuit protection: Stops electrical current from flowing when it senses a short-circuit
• Fault detection and diagnostics: Identifies charging faults and alerts users through LED indicators, fault codes or an integrated display

Safety Doesn’t Stop at Certification

• A certified product won’t be safe for use if it was haphazardly installed. It’s important to have a trusted installer be able to guide you along on installing a charger in a way that remains safe for use and at optimal performance. In addition, installation must comply with guidelines from the Energy Market Authority (EMA) and be carried out by a Licensed Electrical Worker (LEW).
• EV chargers also come in many different forms and features. It’s important to understand what your model does, and this can be achieved by reading through the user manual and learning more about your device.
• Regular maintenance of your charger is a necessary step to prolonging the lifespan of your EV charger while keeping the device safe to use.

Conclusion

Safety should be one of the key considerations when choosing an EV charger, especially since it operates for extended periods and interacts directly with both your property’s electrical system and your vehicle.

By looking for recognised safety standards, regulatory approvals and appropriate protection features, you can have greater confidence that the charger has been designed, assessed and approved for safe operation. Combined with proper installation and regular maintenance, these factors help ensure your charger remains safe, reliable and compliant for years to come.

Summary: What Should You Look For?

Understanding safety standards is an important first step in choosing an EV charger. Beyond certifications, it’s equally important to consider how the charger fits your property, charging habits and long-term requirements. If you’re comparing different options, speaking with a supplier who can explain the differences can help you make a more informed decision.

Frequently Asked Questions

1. What is the most important certification to look for in an EV charger?
There isn’t a single “most important” certification. Instead, look for chargers that comply with recognised IEC standards, carry CE marking where applicable, meet Singapore’s TR25 type approval requirements, and include appropriate protection ratings and built-in safety features.

2. Is CE marking enough on its own?
No. CE marking is valuable, but it should be considered together with EV charging standards compliance, built-in protection features, and suitability for Singapore’s regulatory framework.

3. What IP rating should I look for for outdoor charging?
For most outdoor installations, an IP54 or IP55 rated charger is generally recommended, although the appropriate rating ultimately depends on the installation environment.

4. Does installation affect charger safety?
Indeed, a certified charger requires proper circuit protection, correct earthing, suitable cabling, and installation by qualified professionals. In Singapore, compliance with local installation and certification requirements is essential for charger safety.
