An electric vehicle battery is considered “out of order” when its charging capacity, as measured by SOH (State of Health), falls below 70%. At this point, the vehicle triggers an alert, as the battery can no longer deliver the required performance.

However, this does not mean that the battery is unusable. It simply means that its nominal voltage is lower. For example, a new battery (100% SOH) may have a voltage of 10V. Once its SOH reaches 70%, the voltage will be 7V.

The good news is that this lower voltage can be compensated for. By assembling more cells or modules, it’s possible to achieve the same capacity as a new battery. The result is a reconditioned battery whose lifespan is not altered, and which can be used for new applications.

The key to reusing these batteries is the BMS (Battery Management System). The BMS is the electronic board that manages and balances the battery cells. The vehicle’s original BMS puts the battery into fault as soon as the SOH is too low.

We have developed an innovative BMS that adapts to second-life batteries. It recalculates SOH and adjusts voltages, even at very low levels, to rebalance the cells and make the battery fully functional. Our technology works with any type of battery, enabling you to give these components a second life.

Access to these batteries is surprisingly easy. Most professionals, such as garages and recycling centers, are actively seeking to dispose of them. The main challenge is to identify batteries that can be reused. We’re here to support you in this process and help you get started.

For companies in the energy sector, reconditioning second-life batteries offers considerable advantages:

• Lower costs: you can offer your customers solutions that cost less than new batteries.
• Quality guarantee: a reconditioned battery can be guaranteed to last as long as a new one.
• Ecological positioning: you contribute to the circular economy by giving these batteries a new use, instead of sending them for recycling.

If you want to improve your business or train your teams, we can support and train you on our premises.

Recycling lithium batteries is a complex subject, but one with immense potential. Please consider how this activity might interest you, and we can discuss it together.
