TYVA Energie is certified to ISO 9001 standards.

Why refurbish a lithium battery?

Refurbishment makes it possible to:

  • extend battery lifespan,
  • reduce operating costs,
  • limit vehicle downtime,
  • reduce environmental impact,
  • ensure the performance and safety of energy systems,
  • avoid the premature replacement of complete battery packs.

 

This approach is part of a circular economy strategy and promotes the sustainable management of industrial lithium systems.

The benefits of the TYVA Énergie solution

Environmental impact

- 0 %

Refurbishing lithium batteries extends their lifespan by replacing only defective components. This solution reduces waste and can generate up to 70% less carbon footprint compared to the complete replacement of a battery.

Cost savings

- 0 %

Refurbishing lithium batteries is a more cost-effective alternative to purchasing a new battery. By replacing only the necessary components, this solution enables savings of between 25 and 40%, while extending the lifespan of the equipment.

Performance

0 %

Thanks to the replacement of worn components and post-maintenance testing, batteries regain a high level of performance and reliability equivalent to a new battery. This solution extends their lifespan by 8 to 10 years while ensuring the sustainable use of equipment.
