Question 1

Is AIS 140 mandatory for electric vehicles?

Accepted Answer

Yes, wherever the vehicle is a public service vehicle requiring a permit — the mandate is written by category, not powertrain. Two-wheelers, three-wheelers, e-rickshaws and permit-free vehicles sit outside Rule 125H.

Question 2

Does an AIS 140 device report battery state of charge?

Accepted Answer

No. The packet carries position, speed, heading, network data, ignition state, emergency and tamper status, and the device's own power readings. Battery and charging data comes from the vehicle or the charger.

Question 3

Who certifies an AIS 140 device?

Accepted Answer

The testing agencies named in Rule 126 of the CMVR, principally ARAI and ICAT. Ask for the Type Approval Certificate for the specific make and model, plus current Conformity of Production status.

Question 4

Can one device serve both compliance and fleet operations?

Accepted Answer

By contract, not by certification. The standard requires at least two backend destinations and allows operational ones, but whether your vendor streams a usable copy to an endpoint you control is negotiated.
