Abstract:
A battery charging device ( 30 ) is a battery charging device that charges a battery ( 10 ) used in vehicle ( 20 ), and comprises a battery pairing component ( 32 ), a usage battery state acquisition component ( 33 ), and a charging current determination component ( 37 ). The battery pairing component ( 32 ) is configured to set a charging objective battery ( 10 ) to be paired with a usage battery ( 10 ). The usage battery state acquisition component ( 33 ) is configured to acquire information about the state of the usage battery ( 10 ). The charging current determination component ( 37 ) is configured to determine the charging current of the charging objective battery ( 10 ) on the basis of information about the state acquired by the usage battery state acquisition component ( 33 ).

Claim (Index 5):
The battery charging device according to  claim 3 ,\n further comprising a charging battery state acquisition component configured to acquire a charging state of the charging objective battery set in the pair, wherein the charging battery state acquisition component acquires initial capacity of the charging objective battery, the usage battery state acquisition component acquires initial capacity of the usage battery, the charging current determination component has: a charge/discharge ratio calculator configured to calculate a charge/discharge ratio that is a ratio of difference between the initial capacity and the target charging power amount of the charging objective battery to difference between the initial capacity and the target return capacity of the usage battery; a decrease amount calculator configured to calculate amount of decrease in the usage battery over a specific length of time on the basis of the usage state acquired by the usage battery state acquisition component; and a charge amount calculator configured to calculate charge amount over a specific length of time by finding a product of the decrease amount and the charge/discharge ratio, and the charging current is determined on the basis of the calculated charge amount.
