Abstract
A battery pack with reduced magnetic field emissions includes a plurality of cells (1301,1302) coupled electrically together by a first electrical conductor (1307) and a second electrical conductor (1308). The first electrical conductor (1307) couples positive terminals (1305,1306) to a terminal block (1311), while the second electrical conductor (1308) couples the negative terminals (1303,1304) to the terminal block (1311). Each cell (1301,1302) contains an asymmetrical internal electrode construction (1313,1314) having electrical tabs (502,503) coupled to a cathode and anode. The cells (1301,1302) can be arranged with their corresponding asymmetrical internal electrode constructions (1313,1314) oriented in different directions to reduce magnetic field emissions. The first electrical conductor (1307) and second electrical conductor (1308) can be routed such that magnetic fields generated by discharge currents tend to reduce other magnetic fields produced by other components within the battery pack.
