Debunking the Battery Grail, AIS-156

To protect the user, battery safety is one of the key points that must be considered throughout the production of an Electric Vehicle. The Ministry of Road Transport and Highways has put in a draft to implement new guidelines for EV battery management to assure user safety and prevent any accidents. MoRTH recently postponed the implementation of AIS-156, Automotive Industry Standard, to give manufacturers more time to get ready before the complete implementation, which will be mandated beginning in December 2022 in two phases.

One of the pivotal parts of an electric vehicle is its battery. Also, it is referred to as the powerhouse of an electric vehicle’s motor.  It plays the same role as the fuel tank of a conventional vehicle. It serves as a power storage system. 

Dissecting the AIS-156 into three simpler parts

1. Packing level: AIS-156 mentions that battery packs should be secured from water ingress and gas leaks at the packing level.
2. Cell level: The battery pack should include all relevant cell-related information, such as the cell’s manufacturing date and cell-to-cell spacing. At least 5 charge-discharge cycles are to be recorded. It has to be mentioned on the battery pack to be sure of the functioning of the battery. Manufacturers are required to keep all the data saved with them.
3. Battery Management System: It is like a safety net fastened to an electric vehicle. It controls a rechargeable battery’s environment, prevents it from running outside of its safe operating range, monitors its state, calculates secondary data, reports that data, and balances the battery. The new draft of AIS-156 requires OEMs to make a smart BMS and have all the protection against over current, over charge, over discharge, overflow of Voltage, short-circuit and heat control. 

Besides, to be compliant on all points, Team OSM has long back started the process. We have asked our battery and charger provider to comply with the new AIS-156. Many of the provisions have already been taken care of even before this draft was released. Such as OSM Rage+ has charge voltage cut-off to avoid over charging. We make sure that we comply to all the provisions.
