| 摘要 |
The invention concerns a method ( 300 ) for charging a set of batteries. The method includes the steps of charging ( 314 ) a first battery ( 116 ) with a charging current from a power supply ( 138 ), monitoring ( 316 ) a parameter of the first battery during the charging step and selectively diverting ( 318 ) at least a portion of the charging current used to charge the first battery to charge a second battery ( 118 ). The first and second batteries are charged simultaneously after the parameter of the first battery reaches a predetermined threshold. As an example, the parameter can be a battery voltage or a battery temperature rate.
