As electric mobility rapidly gains traction across the globe, the importance of electric vehicle charger safety and standards can’t be overstated. Whether you’re installing a home charger, setting up commercial charging infrastructure, or operating a public fast-charging network, understanding safety guidelines and regulatory compliance ensures smooth, secure, and long-lasting operation. With the EV ecosystem evolving so quickly, it’s essential to demystify safety requirements and simplify compliance allowing users and operators to benefit from reliable charging while minimizing electrical risks. One company helping streamline this experience is Electreefi, offering advanced EV charging solutions designed with safety, interoperability, and operational reliability in mind.
Why EV Charger Safety Matters
An electric vehicle charger is more than a plug-and-go device. It serves as a critical link between the electrical grid and your EV’s battery, handling high currents, voltage fluctuations, and environmental exposure. If a charger is installed incorrectly, lacks essential protections, or doesn’t meet established standards, it can result in severe hazards from electric shock and short circuits to fires and equipment damage.
Given these risks, safety and compliance are foundational elements in charger design, installation, and operation. Adhering to relevant standards doesn’t just protect users it preserves the integrity of electrical infrastructure and builds trust in EV technology overall.
Key Safety Standards and Certifications for EV Chargers
Electric vehicle charging equipment must comply with a mix of national and international standards. In India, the Bureau of Indian Standards (BIS) has defined specific criteria under the IS 17017 series that address multiple aspects of charger safety and performance.
- IS 17017 – Core Safety and Performance Benchmarks
This series of standards, aligned with international best practices like IEC 61851, covers comprehensive safety and functionality requirements for EV chargers, including:
- Electrical safety and insulation performance
- Thermal and temperature rise limits
- Short-circuit and overload protection
- Plug, socket, and connector specifications
- Electromagnetic compatibility (EMC)
- Mechanical resilience and environmental resistance
Complying with IS 17017 confirms that an EV charger meets essential performance and safety criteria required for legal sales and deployment in India.
- ARAI AIS Standards – AC and DC Charging Requirements
The Automotive Research Association of India (ARAI) maintains Electric Vehicle Standards Specifications (AIS), such as AIS 138 Part 1 & Part 2. These define safety and control requirements for both AC and DC charging systems, ensuring proper interface and communication protocols between the charger and electric vehicle.
- Testing Requirements
Before EV chargers can be certified, they must undergo rigorous testing in accredited laboratories — such as the EV Charger Test & Research Laboratory at CPRI. These facilities verify electrical safety performance, output stability, EMI/EMC compliance, and communication protocols supported by national standards (e.g., IS 17017 and IS/ISO 15118 series).
Essential Safety Features to Look for in EV Chargers
Safety isn’t just about ticking boxes on a compliance form. Chargers should have built-in hardware and software protections that proactively prevent electrical hazards.
Ground Fault and Leakage Protection
Protective systems such as Ground Fault Circuit Interrupters (GFCIs) or Residual Current Devices (RCDs) detect leakage currents or ground faults and automatically disconnect power when anomalies occur. These systems are essential to safeguard users from electric shocks.
Overcurrent and Overvoltage Protection
Chargers should include overcurrent and surge protection mechanisms that guard against unexpected voltage spikes or grid instability. These electrical protections prevent damage to both the charger and the EV battery pack.
Thermal Safety and Temperature Monitoring
Built-in temperature sensors and thermal shutdown capabilities prevent overheating a common issue during long charging sessions or when ambient conditions are extreme. Chargers that meet standards like IEC 61851-1 typically incorporate these protections to prevent damage or fire risks.
Ingress Protection (IP) Ratings
For outdoor installations, IP ratings help ensure the charger’s physical enclosure resists dust and water. A higher IP rating (e.g., IP65 or above) indicates robust protection against weather elements, extending the life and safety of the charger.
Best Installation and Compliance Practices
Even a charger that meets all safety standards won’t perform safely without proper installation. Here are best practices to ensure compliance:
Professional Installation
Always have EV chargers installed by certified electricians or qualified installers. Mishandling electrical connections can negate safety features and lead to dangerous faults.
Proper Wiring and Grounding
Ensure the electrical wiring, grounding, and conduits are sized and configured correctly to match the charger’s load specifications and local electrical codes. Poor wiring can result in overheating or dangerous voltage imbalances.
Routine Inspection and Maintenance
Regular inspection and maintenance help catch wear and tear, loose connections, or environmental damage early. Schedule periodic checks, especially in high-use public or commercial environments.
Compliance: Why It Matters
Legal compliance ensures that EV chargers operate safely and reliably while meeting regulatory requirements for market entry, public deployment, and government projects. Standards like IS 17017 not only deliver baseline safety protections but also instill confidence among EV owners, fleet operators, and infrastructure developers.
For operators and service providers, demonstrating compliance can unlock opportunities in public tenders, partnerships, and large-scale EV projects positioning them as trusted players in the e-mobility ecosystem.
Conclusion
Electric vehicle charger safety and compliance are critical elements of a thriving EV charging ecosystem. As demand for EVs grows, so do expectations around reliability, electrical safety, and regulatory adherence. Whether you’re installing a home charger or expanding a public charging network, understanding and following established safety standards from BIS and ARAI benchmarks to practical protections like ground fault detection, surge protection, and weatherproof enclosures ensures risk-free charging experiences for users everywhere.
With companies like Electreefi driving innovation in smart charging platforms and EV infrastructure, stakeholders can access safer, standards-aligned solutions that power electric mobility with confidence.
Frequently Asked Questions
What safety standards apply to electric vehicle chargers in India?
EV chargers in India must comply with BIS standards such as IS 17017, which cover electrical safety, performance, EMC, and mechanical protections. Additionally, AIS 138 standards from ARAI define requirements for AC and DC charging systems.
Why is BIS certification important for EV chargers?
BIS certification confirms that an EV charger meets established safety and performance standards, validates product quality, and is mandatory to legally sell or deploy chargers in the Indian market.
What built-in safety features should an EV charger include?
Key safety features include ground fault protection (e.g., GFCI/RCD), overcurrent and surge protection, thermal monitoring, and appropriate ingress protection (IP) ratings for environmental resistance.
Do EV chargers need professional installation?
Yes. Professional installation by a qualified electrician ensures that wiring, grounding, and electrical connections meet code requirements, protecting against shocks, faults, and other hazards.
