Abstract
A battery pack charger configured to heat a power tool battery pack, the battery pack charger comprising a housing, an adapter portion integrated with the housing of the battery pack charger, the adapter portion configured to mechanically and electrically connect to the power tool battery pack, and an inductive heater including a coil portion, the coil portion including a coil housing and one or more inductive coil windings, the inductive heater configured to generate an electromagnetic field to heat the power tool battery pack.
Claims20
A battery pack charger configured to heat a power tool battery pack, the battery pack charger comprising:
- a housing;
- an adapter portion integrated with the housing of the battery pack charger, the adapter portion configured to mechanically and electrically connect to the power tool battery pack;
- and
- an inductive heater including a coil portion, the coil portion including a coil housing and one or more inductive coil windings, the inductive heater configured to generate an electromagnetic field to heat the power tool battery pack.
A power tool battery pack charging system, the system comprising:
- a battery pack charger including a housing;
- an adapter portion integrated with the housing of the battery pack charger, the adapter portion including a battery pack interface, the adapter portion configured to mechanically and electrically connect to the power tool battery pack;
- and
- an inductive heater including a coil portion, the coil portion including a coil housing and one or more inductive coil windings, the inductive heater configured to generate an electromagnetic field to heat the power tool battery pack.
A method of inductively heating a power tool battery pack, the method comprising:
- integrating an adapter portion into a battery pack charger;
- coupling an inductive heating assembly to the battery pack charger;
- connecting, mechanically and electrically, the power tool battery pack to the adapter portion;
- and
- generating an electromagnetic field with a coil winding included within a coil portion of the inductive heating assembly to heat the power tool battery pack.
