A charge control apparatus for controlling how to charge a battery unit having a plurality of batteries connected in series, comprising:
- a connection control section operable to divide the batteries into a plurality of groups of batteries by switching connections between the batteries, according to a received current amount indicative of an amount of a current that can be received from one or more external power sources;
- and
- a charge control section operable to charge the groups of batteries in parallel with power received from the external power sources, wherein
- the connection control section is operable to divide the batteries into more groups when the received current amount is greater.
