To provide an auxiliary power source device and an electric vehicle which can suppress power consumption of a main power source.SOLUTION: An auxiliary power source device 20 includes an auxiliary power source 21 and an auxiliary power source control part 22. When power is output to a drive motor 40 from a main power source 11, the auxiliary power source control part 22 makes an auxiliary power source in an output state where the power is output from the auxiliary power source 21 or a non-output state where the power is not output from the auxiliary power source 21. When a required current value W is larger than a predetermined power value, the auxiliary power source control part 22 executes output control of making the auxiliary power source in the output state. When the required current value W is equal to or smaller than the predetermined power value, the auxiliary power source control part 22 executes non-charging non-output control of making the auxiliary power source in a non-output state of a non-charged state.SELECTED DRAWING: Figure 1
【課題】主電源の消費電力を抑えることができる補助電源装置及び電動車両を提供する。【解決手段】補助電源装置20は、補助電源21及び補助電源制御部22を備えている。補助電源制御部22は、主電源11から駆動モータ40に対して電力を出力する場合において、補助電源21から電力を出力する出力状態、あるいは補助電源21から電力を出力しない非出力状態とする。補助電源制御部22は、必要電力値Wが所定電力値よりも大きい場合、出力状態とする出力制御を実行する。補助電源制御部22は、必要電力値Wが所定電力値以下である場合、非充電状態の非出力状態とする非充電非出力制御を実行する。【選択図】図1
