A characteristic, such as State Of Health (SOH) or State Of Charge (SOC), is estimated for an Energy Storage System (ESS) by supplying a pre-determined signal to the ESS, measuring a response signal output by the ESS, and obtaining an impedance spectrum of the ESS. In one example, the ESS is one of several electrochemical battery packs of an electric vehicle. The pre-determined signal is a current signal generated by a switching power converter that transfers charge from the battery pack to other battery packs or transfers charge from the other battery packs onto the battery pack. The pre-determined signal is generated without disrupting any load supplied by the battery packs. The battery pack outputs a voltage signal in response to receiving the pre-determined current signal. A processor obtains an impedance spectrum using the current and voltage signals, and thereby obtains an SOH and SOC estimate of the battery.

The control apparatus is configured to control power supply in response to reception of a power supply request. The one or more processors perform setting a charge start time, starting the power supply to the power system if the power supply request is received before the charge start time, controlling the power of the power supply so that State of Charge in the in-vehicle battery becomes lower than or equal to a predetermined value before the charge start time, and controlling the power of the power supply so as to be lower than or equal to a predetermined upper limit at which increase in deterioration in the in-vehicle battery due to the power supply can be suppressed.
