LITHIUM +

LFP | Lithium Iron Phosphate | LiFePO4
NMC | Nickel Manganese Cobalt | LiNMC

We design and manufacture your customized lithium packs and batteries in France

ACEDIS offers you the study, design and manufacture of your lithium batteries in our workshops in Loiret, France.

We have a wide selection of containers for all installations; depending on your power needs under different voltages (from 12V to 72V) and the available space, we will have the solution.

The lithium technologies currently used by our workshop are LFP (Lithium Iron Phosphate) and NMC (Nickel Manganese Cobalt) in cylindrical or prismatic format.

We also have a wide selection of cells of different capacities with a large choice of BMS.

It is this multitude in the choice of components that allows us to respond to all demands.

Finally, all our packs and batteries are systematically tested during and at the end of production.

APPLICATIONS

Cylindrical or prismatic cells

LFP | Lithium Iron Phosphate | LiFePO4

Best option for cycling:
+ 3000 cycles
Safest technology (marginal thermal runaway risk)

NMC | Nickel Manganese Cobalt | LiNMC

Best option for volume capacity
Without any maintenance
Low self-discharge (<3% per month)
Performance maintained from -20°C to +60°C
Weight gain

Lithium packs

LiFePO4 and LiNMC in ABS container or thermoformed sheath

Whatever your needs and constraints, we study and create a tailor-made solution:

Choice of technology

BMS Selection

Choice of assembly

BMS | Battery Management System

BMS are essential components for the proper functioning of lithium batteries.

They ensure proper management of charging and discharging conditions.

They ensure battery safety in extreme operating conditions.

Overvoltage and deep discharge protection
Protection against extreme high temperatures:

=> Under load: 0°C - +50°C

=> In discharge -20°C - +60°C

Real-time battery charge status

Overcharge and discharge protection
Cell Load Management and Optimization and Balancing
The BMS automatically reactivates when operating conditions return to normal.
