What is inside the PMV EaS-E battery pack
The PMV EaS-E carries a 13.3 kWh pack built from LFP Prismatic (LiFePO4) cells arranged in 6 serviceable modules at a nominal 260 V. Pack mass lands near 98 kg including the enclosure, cooling plate, contactors and BMS harness.
Because the cells are LFP Prismatic, the recoverable value profile is dominated by lithium, copper and aluminium rather than nickel and cobalt. That decides whether a retired pack is worth repurposing, refining, or both.

Step 1 — Removing and shipping a passenger pack
Packs are dropped on a vehicle lift using the OEM procedure and a rated battery table, then isolated at the service disconnect. Retired packs are UN 3480 or UN 3481 dangerous goods, so the pack must be below 30% state of charge and any deformation, swelling or thermal history declared before pickup.
One pack per UN-rated pallet box, strapped and restrained, with terminals capped and coolant ports sealed. Dealer and workshop returns are consolidated into full truckloads, typically eight or more packs per run.
- Pull the service disconnect and record pack voltage
- Drain or cap coolant lines before lifting
- Photograph the pack casing and any impact damage
- Keep the VIN and pack serial together on the manifest
Step 2 — Module-level state of health grading
Each of the 6 modules is tested independently — a whole-pack SOH figure hides the spread that decides second-life eligibility. We run a full capacity cycle, DC internal resistance measurement and impedance spectroscopy.
Our degradation model for the PMV EaS-E shows how value falls with age. Measured results replace these estimates once the pack is on the bench.
| Service year | Modelled SOH | Grade | Residual value |
|---|---|---|---|
| Year 2 | 95.6% | A — BESS ready | USD 693 |
| Year 4 | 92.5% | A — BESS ready | USD 671 |
| Year 6 | 89.4% | A — BESS ready | USD 649 |
| Year 8 | 86.3% | A — BESS ready | USD 621 |
| Year 10 | 83.2% | B — Second life | USD 521 |
Step 3 — What you actually recover
For modules routed to refining, a pack of this size and chemistry typically yields about 2.2 kg lithium, 0.0 kg nickel, 0.0 kg cobalt and 6.7 kg copper.
At 80% SOH our model sends about 56% of the pack to second life, worth USD 343, and credits USD 83 for the remainder as black mass. Avoided emissions come to roughly 595 kg CO2.
Field note
Step 4 — Where to send it and what paperwork you get
PMV EaS-E packs are received directly at 8 intake sites in its markets, including Chakan, Maharashtra, Sanand, Gujarat, Taloja, Maharashtra, Narela, Delhi. From there, modules move to the nearest grading bench and refinery.
Every consignment closes with a certificate showing quantity processed, recovery percentages achieved and downstream vendor disclosure, in the form needed for CPCB EPR filings under the Battery Waste Management Rules 2022. Fleets retiring several PMV EaS-E units should book one consolidated pickup to cut per-pack cost.
