SOLID-STATE ACTIVE SWITCH MATRIX FOR HIGH ENERGY, MODERATE POWER BATTERY SYSTEMS

摘要

A battery management system employs electronic switches and capacitors. No traditional cell-balancing resistors are used. The BMS electronically switches individual cells into and out of a module of cells in order to use the maximum amount of energy available in each cell and to completely charge and discharge each cell without overcharging or under-discharging.

主权项

1. A battery module comprising:
a plurality of cells connected to one another electrically; a plurality of sensors configured to measure properties of the cells and of the battery module; and an electronic switch assembly associated with each cell; wherein the switch assembly is configured to remove its associated cell from service when directed to by a computer system; and wherein the electronic switch assembly is configured to establish direct electrical connection between cells adjacent to the removed cell.
