Following several EV fire incidents in 2022, the Ministry of Road Transport and Highways (MoRTH) implemented AIS-156 Amendment 2 standards for L-category electric vehicles (2 and 3-wheelers). The standards mandate strict design safeguards, including cell-to-cell propagation prevention, active thermal management, and a smart BMS that logs battery data permanently, protecting users from thermal runaway risks.
Energy and EV mobility networks operate at the intersection of electrical hardware engineering and cloud telematics. Product managers design dynamic load-balancing systems, state-of-health degradation algorithms, and low-latency communication brokers (MQTT) to manage battery pack charge cycles. The BMS firmware must monitor thermal profiles to comply with AIS-156 safety requirements, trigger emergency solenoids, and log metrics. Integrating with local grid utility SCADA APIs allows fleet depots to peak-shave electricity draw, shifting consumption to off-peak slots while keeping the EV charging UX frictionless via UPI AutoPay integration.
Under AIS-156, the Battery Management System (BMS) must monitor individual cell temperatures and voltages. If a single cell's temperature exceeds a safety limit (typically 55°C), the BMS firmware triggers a warning state, reducing current draw (derating) to cool the pack. If temperature continues to rise, the BMS opens the contactors, isolating the pack from the vehicle's motor.

AIS-156 requires the BMS to maintain a permanent, unalterable log of battery parameters, including charge/discharge cycles, temperature anomalies, and cell imbalances. This data acts as a flight data recorder (black box) for the battery. In the event of a failure, forensic engineers retrieve the logs to analyze the root cause of the breakdown.

The BMS firmware must prevent the battery from operating outside safe voltage limits. Over-charging leads to lithium plating and short circuits, while over-discharging degrades cell chemistry. The BMS implements multiple redundant safety cut-offs, communicating with the vehicle's charger over CAN bus to stop current inflow once the battery reaches 100% capacity.

To sell EVs in India, manufacturers must certify their batteries with testing agencies like ARAI or ICAT. The certification process involves drop tests, nail penetration tests, thermal shock tests, and electromagnetic compatibility (EMC) testing. Having structured firmware telemetry reports that demonstrate the BMS safety limits are functioning helps speed up the certification process.
