Office Memorandum
Subject: Testing parameters to enhance Human Safety of Electric Vehicles incentivised
under (i) Production Linked Incentive (PLI) scheme for Automobiles and auto
components (ii) PLI scheme for Advance Chemistry Cell (ACC) and (iii) FAME II scheme
of Ministry of Heavy Industries (MHI).
To safeguard Human Safety, certain tests which are done internationally will be made
mandatory from 1* April 2023 for claiming incentives/payouts under the PLI schemes for
Automobile and Auto components, ACC and FAME II scheme being implemented by MHI.
2. It is reiterated that these tests enhance Human Safety by ensuring quality at the 3
levels i.e. (i) Battery Pack (ii) Battery Management System (BMS) and (iii) Cell level. The
details of the tests are Annexed.
3.5 These tests are widely carried out and accepted internationally for safeguarding Human
Safety and thus would be made mandatory for the above referred schemes of MHI w.e.f. 1°
April 2023 as a precondition for claiming incentives.
4. If any of these tests fall under CMVR guidelines having implementation timelines
before 1* April 2023 then CMVR timelines will take precedence.
