Abstract: The present disclosure relates to a charger 1 for a battery-operated system, configured to charge a battery pack 21, the charger comprising a housing 3 and a charging socket 5 in the housing for receiving a battery pack. Charging electronics provide a direct current to electric connectors 7 associated with the charging socket for charging the battery pack. A fan arrangement 9 is provided, force cooling the battery pack during charging. The housing 3 comprises a fan compartment 11, enclosing the fan 9, and an electronics compartment 13, enclosing the charging electronics. The fan compartment 11 and the electronics compartment 13 are separated at least by a wall 15.

Abstract: The present disclosure relates to a battery-operated system comprising a tool (1), a battery pack (3) configured to power the tool by being inserted in a tool socket (5) of the tool, and a charger (7), comprising a charger socket (9) for charging the cooling channel (13) extending from a first (15) to a second (17) opening in the housing. The tool (1) comprises a fan arrangement (19) for cooling the battery pack (3) during use by forcing air from battery pack (3). The battery pack (3) has a housing (11) and a the first (15) to the second (17) opening in the battery pack housing (11), and the charger (7) comprising a fan arrangement (21) for cooling the battery pack (3) during charging but instead forcing air housing (11). This means that a battery cell that may become the hottest during discharging is cooled at ambient temperature during charging meaning that full charging can be attained faster.
