Conventional chargers for a pack of batteries associated in serial give a total voltage for 4 elements equal to xVxn, x depending of technology and a same current for all unit cells.
In BILAPS the battery management system is made of:
- X slave chargers of each cell with a profile of charge depending of the bipolar technology;
- 1 master in relation with: slave charges to give charge profile + test bench;
- 3 slave chargers on prototype have been manufactured and tested;
- After test some modifications have been introduced;
- 36 slave charges have been developed with dimensions 120x70x12 mm;
- The slave chargers are connected to the cells via faston clips.

The process of lead-alloy plating of conductive fluorpolymer bipolar plates was developed on a laboratory scale. An ECD (Electro Chemical Deposition) pilot plating line, capable of semi-industrially plating the bipolar plates with a well defined lead alloy coating was build, tested and used for small series production. The process includes pre- and post treatment of these difficult to plate materials.
- What are the potential applications for this result?
Coating bipolar plates and grids for the BILAPS power source.
- Who are the end-users of this result?
Electro plating companies and battery manufacturers.
