Voltage measuring circuit of battery pack

摘要: A voltage measuring circuit (2) of a battery pack comprising at least one or more blocks each composed modules connected in series. Voltage lines (21 to 26) are led from points (V1 V6) the (1), line (23) is grounded, and other non-grounded grounded detection wire via branch (31 35). division resistor interposed wire, an operation (5) analog-digital converter (4). The calculate module based on measurement data input line. number parts can be reduced, accuracy improved, disconnection reliably detected thereby.
