A battery system may include a controller and multiple parallel connected battery strings, with each string including at least one battery, a passive overcurrent protection device and an active overcurrent protection device. The passive overcurrent protection device may be configured to disconnect the string from the battery system when an electrical current in the string exceeds a first threshold value, and the active overcurrent protection device may be configured to disconnect the string from the battery system upon activation by the controller. The controller may be configured to (a) activate a first active overcurrent protection device of a first string of the multiple strings at a first time, and (b) activate a second active overcurrent protection device of a second string of the multiple strings at a second time different from the first time.
