Claim 6:
7. The energy transfer circuit according to claim 6, wherein
the controller is configured to control, in this order,
a first state for controlling a corresponding one of the first wiring side switches and a corresponding one of the at least one second wiring side switch connected to the nodes on both sides of a discharge cell to be discharged among the n cells to an on state, and the first clamp switch and the fourth clamp switch or the second clamp switch and the third clamp switch to an on state,
a second state for controlling the corresponding one of the first wiring side switch and the corresponding one of the at least one second wiring side switch connected to the nodes on both sides of the discharge cell to an off state, and the second clamp switch and the fourth clamp switch or the first clamp switch and the third clamp switch to an on state, and
a third state for controlling the corresponding one of the first wiring side switch and the corresponding one of the at least one second wiring side switch connected to the nodes on both sides of a charging cell to be charged among the n cells to an on state, and the first clamp switch and the fourth clamp switch, or the second clamp switch and the third clamp switch to an on state to allow a current to flow through the charging cell.
