摘要： 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.

摘要： A blower may include a housing having a handle, an electric motor powered by a battery pack, and a fan assembly operably coupled to the electric motor to force air through a blower tube responsive to operation of the electric motor. The blower tube defines a blower tube axis. The fan assembly creates a low pressure area in a intake chamber that provides the air to the fan assembly. The air enters the intake chamber via at least one radial entrance and an axial entrance disposed in the housing. The axial entrance is configured to receive cooling air that has passed through the battery pack.
