AIS 156 Explained: What India's Battery Safety Standard Means for You

AIS 156 is the Automotive Industry Standard that governs the safety of batteries used in electric vehicles in India. After several high-profile EV fire incidents, the standard was strengthened to ensure that every battery sold for EV use meets rigorous safety benchmarks before it reaches the road.

So what does AIS 156 actually test? The standard covers thermal propagation (how a single faulty cell affects its neighbours), short-circuit protection, overcharge and over-discharge behaviour, vibration and mechanical shock resistance, and overall pack-level safety. A battery that passes has demonstrated it can contain faults rather than cascade into a dangerous failure.

For buyers, AIS 156 certification is the clearest signal that a battery has been engineered and validated for safety — not just assembled to hit a price point. Every Maxvolt EV battery is AIS 156 certified, and our manufacturing includes multi-stage testing for charge/discharge cycling, thermal stress and BMS validation before any pack leaves the facility.

How do you verify a certificate is real? Ask for the Type Approval Certificate (TAC) that lists the specific battery model and rating. Maxvolt publishes its TAC certificates for models such as the 51.2V 105Ah e-rickshaw pack and multiple e-scooter packs, and they are available to view in full on our certificates page.

The bottom line: never compromise on certification. A certified battery costs a little more, but it protects your vehicle, your investment and — most importantly — your safety.
