Description

図１、図５に示すように、下部ハウジング２３０内部の下側部２２４と電池セル２０２との間には、受電コイル２４０が配置されている。受電コイル２４０は、基板２０８の充電回路２５２と給電線たるワイヤ２０６を介して接続されている。受電コイル２４０は、電力供給装置３００から電磁誘導により電力を供給され受電することにより、電池セル２０２の充電電力の供給源となる。ワイヤ２０６は、ハウジング２２０、２３０の内部であって、側面部２２２、２２８と電池セル２０２との間を通って受電コイル２４０と充電回路２５０とを接続している。 As shown in FIGS. 1 and 5 , the power receiving coil 240 is disposed between the lower side portion 224 inside the lower housing 230 and the battery cell 202. The power receiving coil 240 is connected to the charging circuit 252 of the substrate 208 through a wire 206 serving as a power feeding line. The power receiving coil 240 is supplied with electric power from the power supply device 300 by electromagnetic induction and receives power, thereby becoming a supply source of charging power for the battery cell 202. The wire 206 is inside the housings 220 and 230 and passes between the side portions 222 and 228 and the battery cell 202 to connect the power receiving coil 240 and the charging circuit 250.

図１に示すように、本実施の形態による電池パック２００と接続される電動工具１００は、例えば電動ドリルなどであり、本体部１０２、本体部１０２から延出して形成されるハンドル部１０６、および本体部の先端に取り付けられたドリルビット１０４を有している。本体部１０２の内部には駆動回路１１３が形成され、ハンドル部１０６内部にはモータ１１５が備えられている。ハンドル部１０６の下端部には、電池パック２００と電気的に接続するための端子１１１を備えている。電動工具１００は、端子１１１を介して電池パック２００と接続されることにより給電され、駆動回路１１３がモータ１１５を駆動することによりドリルビット１０４を駆動し、所定の作業を行うように構成されている。 As shown in FIG. 1, the electric power tool 100 connected to the battery pack 200 according to the present embodiment is an electric drill, for example, and includes a main body portion 102, a handle portion 106 formed to extend from the main body portion 102, and It has a drill bit 104 attached to the tip of the main body. A drive circuit 113 is formed inside the main body portion 102, and a motor 115 is provided inside the handle portion 106. A terminal 111 for electrical connection with the battery pack 200 is provided at the lower end of the handle portion 106. The power tool 100 is configured to be supplied with power by being connected to the battery pack 200 via the terminal 111, and to drive the drill bit 104 by driving the motor 115 by the drive circuit 113 to perform a predetermined work. Yes.
