Battery management system (BMS) for bipolar battery

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. What are the potential applications for this result? - New technology batteries; - Applications with associated batteries in series Who are the end-users of this result? - Car manufacturers, ship builders, energy supply companies, all sectors of activities with batteries. What are the main innovative features/benefits? (Technical/commercial success factors) - Increasing charge and discharge cycle of all types of battery Analysis of the market or application sectors: - See above Potential barriers: - Costs.

Process of the lead plating of the bipolar plate

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. - What are the main innovative features/benefits? (Technical/commercial success factors) Know how of handling, pre- and post treatment and ECD processing of non-metallic conducting materials. -Analysis of the market or application sectors: Bipolar batteries. -Potential barriers: Cost, yield, protection of knowledge (mainly know how).Relation between grain size of the base material and the porosity of the electroplated top layer.
