MHI Tightens PM E-DRIVE Norms, Mandates Higher Localisation for EV Truck Components
The Ministry of Heavy Industries has amended the PM E-DRIVE Phased Manufacturing Programme, mandating higher localisation for EV truck components, with DC-DC converters and VCUs further tightened from September 2026, and Battery Management System (BMS) manufacturing made fully domestic from September 1, 2026, with imports allowed till August 31, 2026.

This latest notification from the Ministry of Heavy Industries updates the localisation requirements for three important components: Battery Management System (BMS), DC-DC converter and Vehicle Control Unit (VCU).
Under the revised norms, manufacturing of critical components such as Battery Management Systems (BMS), DC-DC converters, and Vehicle Control Units (VCU) will be required to be carried out domestically with higher levels of localisation.
For BMS, domestic manufacturing – covering assembly of electronic components, wiring, connectors, heat sinks, enclosure fitment, and software/firmware flashing – will be mandatory from September 1, 2026, while imports will be permitted only until August 31, 2026.
Similarly, DC-DC converters and VCUs will follow a phased localisation roadmap. From September 1, 2025, domestic manufacturing includes integration of assembled PCBAs along with wiring, fitment and flashing. From September 2026, the requirement becomes stricter, moving to assembly of electronic components, semiconductors and connectors on the PCB in India.
The amendments are part of the government’s broader push to deepen localisation, reduce import dependence, and build a resilient domestic supply chain for electric mobility under the PM Electric Drive Revolution in Innovative Vehicle Enhancement (PM E-DRIVE) scheme.
