Abstract
One aspect of the present disclosure is an inspection apparatus of a battery pack for an on-site electric apparatus, which comprises a coupler, a discharger, a changer, a discharge performing device, a voltage value detector, and a calculator. The changer detects one of a nominal voltage value of the battery pack coupled to the coupler and a voltage value of a battery in the battery pack, and reduces a discharge time of the battery and/or a discharge current value of the battery as the detected value is larger.
