Abstract
The disclosure relates to a battery back for a hand-held power tool comprising a battery pack housing. An interface of the battery pack housing has contact elements for contacting corresponding counter contact elements on the hand-held power tool and/or the charging device. A battery pack electronics system comprises a charge current path and a discharge current path. The charge current path is designed to connect the contact elements to the battery cell during a charging of the at least one battery cell, while the discharge current path is designed to connect the contact elements to the battery cell during a discharging of the at least one battery cell. The charge current path and the discharge current path are at least partially electrically separate from one another. The battery pack also comprises a first switch element for switching between at least the charge current path and the discharge current path.
