<p>In a battery degradation monitoring system (1) provided with a battery monitoring unit (11) including a temperature sensor (11b) for detecting the ambient temperature of a battery (2) mounted on a vehicle and a clock function unit (11a) to compute the state of charge and the degradation rate of the battery (2) as a whole by inputting the voltages and temperatures of a plurality of battery modules (3) of the battery (2) from cell monitoring units (10) when an ignition switch (13) of the vehicle is on, the battery monitoring unit (11) is further actuated by the clock function unit (11a) each time a predetermined period of time elapses when the ignition switch (13) of the vehicle is off to integrate a degradation function formula with respect to the ambient temperature detected by the temperature sensor (11b) and compute the degradation rate of the battery (2) when the ignition switch (13) is off.</p> |
