NIMH BATTERIES

NiMH battery with cylindrical modules

NiMH (Nickel Metal Hydride) cylindrical batteries are key components in the urban and industrial energy transition. Known for their robustness and thermal tolerance, they are used in a wide range of systems, from hybrid vehicles to connected street furniture.

At Be Energy, we are experts in diagnosing and regenerating these modules, restoring them to their original performance while avoiding costly and polluting replacements.

What is the reason for the prevalence of the cylindrical NiMH format?

Cylindrical cell assemblies are preferred for demanding applications thanks to their unique properties:

  • Optimal heat dissipation: Their tubular shape allows for efficient air circulation, preventing overheating during intensive charging cycles, even in direct sunlight (street furniture).

  • Safety and stability: Unlike other chemistries, NiMH is very stable, which is crucial for installations in public spaces.

  • Maintainability: The modular architecture allows weakened elements to be precisely targeted for regeneration or replacement without discarding the entire pack.

Where are cylindrical NiMH batteries used?

Street Furniture and Smart Cities

 

You may not see them, but cylindrical NiMH modules are everywhere on our streets:

  • Connected bus shelters: Powering lighting, real-time information screens, and USB charging ports.

  • Advertising panels and totems: Management of dynamic displays and night lighting, often coupled with solar panels.

  • Lighted signage: Backup systems for traffic lights or autonomous beacons. Be Energy supports local authorities and advertising agencies in the maintenance of these battery parks to guarantee 24-hour service.

Hybrid electric vehicle (HEV)

 

This is the primary use for cylindrical NiMH modules. They are used in the fleets of STELLANTIS (Peugeot, Citroën, DS), Porsche, and Honda.

Regenerating these modules restores the initial electric range by eliminating the “memory effect” of the chemistry.

NiMH and regeneration: The winning and safe alternative

Over time, NiMH batteries experience an increase in internal resistance, which reduces their autonomy. Our industrial process does more than just recharge the battery; it thoroughly restores it.

Our technical protocol :

 

  1. High-precision diagnosis: Individual analysis of each module to identify faulty cells.

  2. Desulfation treatment: Use of our proprietary equipment to regenerate the internal chemistry.

  3. Balancing and testing: Validation of charge capacity and discharge power under stress.

  4. SOH certification: Provision of a comprehensive health status report.

The economic advantage: Regeneration generally costs 50% to 80% less than a new battery, while giving your equipment a second life.
