METHOD AND DEVICE FOR MONITORING BATTERY CELLS OF A BATTERY PACK AND METHOD AND ARRANGEMENT FOR BALANCING BATTERY CELL VOLTAGES DURING CHARGE
摘要
A battery monitoring device of a battery pack configured for powering a cordless power tool may include an integrated circuit connected to a microprocessor of the pack that is external to the integrated circuit, and which is connected to each of N battery cells of the pack. The integrated circuit may be configured to take, singly or sequentially, a sampled reading comprising one of an individual cell voltage or a total pack voltage for all cells in the pack. The sampled reading is filtered in the integrated circuit prior to being read by the microprocessor.
