The obligation

From 1 April 2027, an Indian battery has to record its own life.

CEA Chapter XA makes cell-level data capture, ten-year retention and a file the Electrical Inspector reads into legal duties. Most containers arriving in India today cannot do it, and their vendors have no Indian entity.

Countdown

This is a date, not a forecast.

Notified 27 March 2026. Nothing about it is conditional.

Scope, commonly got wrong. Applies above 650 V measured at the point of connection, not at the DC string. A 400 V pack behind a PCS connecting at 11 kV is fully inside it.

Clause by clause

What it actually says.

Every row carries the regulation number so a hostile reader can check it against the gazette.

  • 122(B)(5)(a)

    The BMS shall monitor and record voltage, temperature and thermal runaway at cell, module and rack level, and current at rack level.

    Per-cell data capture becomes a legal duty, not a design choice. Most containers arriving in India today do not expose it.

  • 122(B)(2)

    Two-fault tolerance.

    A single failure must not propagate, and both the design and the evidence have to show it.

  • 122(C)(1)

    Forced ventilation with automated louvres.

    Thermal management becomes inspected rather than assumed.

  • 122(F)(1) and (2)

    Detection and suppression, per container.

    Per container, not per site.

  • 122(M)(2)

    Audit report to the Electrical Inspector.

    Somebody has to assemble a defensible file. Owners are discovering it is them.

The part nobody has pricedThe notified text deleted every hard number from the June 2025 draft, the 7.5 m setback, the 3 m inter-container spacing, the 2-hour fire rating, and replaced them with 'as per relevant standard'. New Reg 137 gives CEA three months from commencement to publish that list, so it lands around 1 July 2027 and nobody yet knows what it will say.
