Battery Pack Discharger RE-GEN 90
Short Description
Cellavie's RE-GEN 90 Pack Discharger turns battery deactivation from a cost into a return. It discharges end-of-life high-voltage EV packs fully to 0 V, leaving them electrically dead and safe to dismantle. It handles packs of up to 950 V at up to 220 A in a thermally controlled cycle, watched live by an integrated thermal camera. Where conventional dischargers burn the remaining energy off in resistors, the RE-GEN 90 feeds up to 90 kW back into the grid or an on-site battery, recovering up to 96% of the energy still in the pack.

Specifications & Service
The RE-GEN 90 Pack Discharger makes end-of-life high-voltage EV battery packs safe to dismantle, transport and recycle, and recovers their energy instead of wasting it. It is built for battery recycling, disassembly and second-life processing facilities, as well as for reverse-logistics stakeholders, since new transport regulations increasingly require packs to be discharged before shipment. The RE-GEN 90 brings full packs down to 0 V for safe discharge and deactivation ahead of dismantling. It is a safer and faster alternative to resistive discharge: where conventional systems burn the pack's remaining energy off as heat, the RE-GEN 90 feeds it back to the grid or an on-site BESS.
- Regenerative discharge: up to 90 kW rated grid feed (92 kVA max apparent power), recovering up to 96% of the remaining energy
- Wide electrical envelope: 950–0 V battery voltage range, 220–0.1 A discharge current, CC mode with thermal current derating
- Thermally controlled: an integrated FLIR AX8 thermal camera monitors the pack live and automatically adjusts discharge power against set thresholds
- Fast: discharges 50% SOC in under an hour by balancing temperature and C-rate
- Chemistry-agnostic: operates on DC voltage and current parameters rather than a specific chemistry, covering standard HV EV pack chemistries (NMC, LFP, etc.); handles one pack at a time
- Self-protecting: overvoltage detection before the connection is established, DC reverse-polarity protection with minimal heat dissipation at 0 V, and pre-charge of the input side
- Connected: Qt-based operator UI, OTA updates, MQTT/REST API layer, and Grafana-based dashboards for throughput, kWh and utilization reporting. Automated BMS readout is in development, with a working proof of concept already demonstrated.
- Expandable: RE-GEN 2 module dischargers reuse the RE-GEN 90's inverter and power distribution module to extend discharge down to module level
Every discharge is logged: voltage, temperature, and duration: to a central database. The system is TRL 9, with dischargers operational within a recycler, and MRL 7–8: a repeatable production system is in place, though not yet a high-volume factory.
