Safe and efficient high-voltage battery discharge for recycling processes

The HV battery discharger is a fundamental solution for the safe treatment of lithium-ion batteries and EV battery modules within modern recycling plants.

This system allows the controlled reduction of residual voltage, eliminating electrical hazards and enabling the next steps of the recycling process in full safety.

Designed for integration in battery recycling lines, the unit performs a deep discharge up to 96V with high efficiency and process reliability.

Why battery discharge is essential in lithium battery recycling

Discharging high-voltage batteries is a critical phase in the treatment of:

• Electric vehicle battery packs

• Lithium-ion modules

• Energy storage system (ESS) batteries

• Hybrid and industrial batteries

The controlled discharge:

• neutralizes dangerous residual energy

• reduces fire and thermal runaway risks

• allows safe handling and storage

• simplifies logistics and transport operations

After the deep discharge, the modules can be short-circuited and placed in a 72-hour quarantine and monitoring phase.

Following inspection, batteries can be classified as non-critical, significantly reducing transport and storage costs.
