About SwitchESS
Issues resolved
In traditional storage batteries architectures, a battery stores energy to restore it in direct current, requiring the use of an inverter and a charger (a “power converter”) in order to connect the battery to the electrical distribution network in alternating current. The power converter directly influences the performance, reliability and overall efficiency of the energy storage system. Moreover, battery performance depends on the performance of the weakest cell.
Solution
SwitchESS designs, develops and manufactures (hardware and software) an all-in-one revolutionary switched cell technology which integrates inverter / charger / battery management systems functions for battery energy storage systems.
This disruptive solution features :
- Improved power conversion efficiency
- Differential management of the charging status of each cell
- Exclusion of a failed cell ensuring continuity of service
- Ability to mix cells with heterogeneous chemistries or health states
- Reduction of the CEM emission
- Reduction of SoC and SoH error estimation
- Autonomy improvement
- Life time improvement
- Simplified diagnostic & maintenance
