Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
A battery discharging apparatus comprising: (a) a discharge means for discharging tile battery, (b) a control means for controlling tile discharge means, and said control means provided with (1) a current sensing means to determine whether or not power is flowing to or from tile battery, and (2) a battery power capacity sensing means to determine battery capacity, wherein tile control means controls the discharge means to begin battery discharge when said current sensing means determines that power is not flowing to or from the battery, and further, said battery power capacity sensing means determines that battery capacity is below a prescribed value.
Claim 2
Dependent Claim
