Abstract
A charger for a plurality of cells comprises a plurality of cells, a plurality of DC power sources, a common DC source in electrical communication with each of the plurality of DC power sources, and a CPU configured to selectively control the connection between each DC power source and the corresponding cell. Each DC power source of the plurality of DC power sources is selectively connectable to a corresponding cell of the plurality of cells.
Claims20
A charger for a plurality of cells, the charger comprising:
- a plurality of cells;
- a plurality of DC power sources, wherein each DC power source of the plurality of DC power sources is selectively connectable to a corresponding cell of the plurality of cells;
- a common DC source in electrical communication with each of the plurality of DC power sources;
- and
- a CPU configured to selectively control the connection between each DC power source and the corresponding cell.
A method of charging a plurality of cells assembled into a battery, the method comprising:
- selectively connecting each DC power source of a plurality of DC power sources to a corresponding cell of a plurality of cells;
- monitoring a current and voltage supplied to each corresponding cell from each DC power source;
- comparing, by a CPU, the current and voltage supplied to each corresponding cell to a charging protocol for each corresponding cell, wherein each cell of the plurality of cells has an individual charging protocol selected from a plurality of charging protocols;
- selectively disconnecting each DC power source based on completing the charging protocol for each cell;
- disconnecting, by the CPU, the plurality of DC power sources from the plurality of cells;
- connecting the plurality of cells together to form the battery;
- and
- supplying a load using the battery.
