Abstract
A charging system for a battery device of a handheld tool includes a charging device provided to inductively charge the battery device in a charging operation, the charging device having at least one induction charging unit which has at least one charging coil having a main coil extension. A gap is provided between the battery device and the charging device in a charging operation. A ratio between (i) the at least one main coil extension and (ii) a minimum clearance between the at least one charging coil and a surface defining the gap is at most 30/1.
Claims6
A charging system for a battery device of a handheld tool, comprising:
- a charging device configured to transmit a charging energy inductively to the battery device, the charging device having at least one induction charging unit including at least one charging coil having a main coil extension;
- and
- a gap situated between the battery device and the charging device, wherein a ratio between (i) the main coil extension and (ii) a minimum clearance between the at least one charging coil and a first surface defining the gap is at most 30/1.
A battery system, comprising:
- a battery device;
- and
- a charging device configured to transmit a charging energy inductively to the battery device, the charging device having at least one induction charging unit including at least one charging coil having a main coil extension;
- wherein a gap is situated between the battery device and the charging device, and wherein a ratio between (i) the main coil extension of the at least one charging coil and (ii) a minimum clearance between the at least one charging coil and a first surface defining the gap is at most 30/1;
- and
- wherein the battery device includes a second induction charging unit which has a second charging coil having a main coil extension, wherein a ratio between (i) the main coil extension of the second charging coil and (ii) a minimum clearance between the second charging coil and a second surface defining the gap is at most 30/1.
