Title:
BATTERY MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/006668
Kind Code:
A1
Abstract:
Disclosed is a battery monitoring device, which reduces a difference between the timing of detecting a voltage value and the timing of detecting a current value, and obtains a more accurate battery state. On a circuit board, a second voltage detection circuit 22b is disposed closer to an output end of a voltage input circuit than a first voltage detection circuit 21b and a current detection circuit 23b, and the current detection circuit 23b is disposed closer to an output end of a current input circuit than the second voltage detection circuit 22b and the first voltage detection circuit 21b, and the voltage input circuit and the current input circuit are disposed closer to the second voltage detection circuit 22b and the current detection circuit 23b than the first voltage detection circuit 21b.
