Abstract

The utility model belongs to the technical field of power supplies, and particularly discloses a battery monitoring device, which comprises a current measuring unit arranged in a main circuit of a battery loop and used for collecting current information of the battery loop; the voltage measuring unit is used for collecting voltage information output by the battery; the temperature measuring unit is used for collecting temperature information of the surrounding environment of the battery or the battery; and the CPU is used for receiving the current information, the voltage information and the temperature information and carrying out calculation so as to obtain digital format data of current, voltage and temperature. The utility model has the advantage that each single battery in the low-voltage end battery can be independently detected and monitored. Moreover, three important monitoring parameters, namely voltage, current and working temperature, of the battery can be synchronously completed through one monitoring device, and the three important monitoring parameters do not need to be respectively detected in the prior art, so that the detection efficiency is improved.
