Methods and apparatuses rechargeable battery pack chargers |
摘要 |
A system, method and apparatus for charging rechargeable battery packs having redundant safety systems. A battery charger has a temperature sensor at a negative charging terminal for determining the charge condition of a rechargeable battery pack and controlling a charging current. The battery charger has a microcontroller to control the charging of the rechargeable battery pack using a fast charge current or a trickle charge current. Independent safety systems provide safe operation of the battery charger if the microcontroller operation fails. A rechargeable battery pack has a pair of openings to allow direct contact to a positive pole and a negative pole of the end batteries for improved temperature sensing by a battery charger.
