The invention discloses a charging circuit, a control method, a vehicle-mounted integrated power supply and a vehicle, relates to the technical field of new energy automobile power supplies, and aims to improve the charging efficiency. The charging circuit comprises a booster circuit, a direct connection circuit and a controller. The input end of the booster circuit is connected with the charging pile, the output end of the booster circuit is connected with the battery, the input end of the direct connection circuit is connected with the charging pile, and the output end of the direct connection circuit is connected with the battery. The controller is connected with the battery, the booster circuit, the direct connection circuit and the charging pile. And the controller controls the direct connection circuit to be conducted and controls the booster circuit to be disconnected under the conditions that the booster circuit is conducted and the charging pile meets the condition of switching direct connection charging, so that the charging pile charges the battery through the direct connection circuit instead of charging the battery through the booster circuit. And when the direct connection circuit is switched on and the switching signal is received, the direct connection circuit is controlled to be switched off after the boosted circuit is controlled to be switched on.
本发明公开了一种充电电路、控制方法、车载集成电源以及车辆,涉及新能源汽车电源技术领域,旨在提高充电效率。充电电路包括升压电路、直连电路和控制器。升压电路的输入端与充电桩连接,升压电路的输出端与电池连接,直连电路的输入端与充电桩连接,直连电路的输出端与电池连接。控制器与电池连接,控制器与升压电路连接,控制器与直连电路连接,控制器还与充电桩连接。控制器在升压电路导通,且充电桩满足切换直连充电的条件的情况下,控制直连电路导通,且控制升压电路断开,以使充电桩通过升压电路为电池充电切换为通过直连电路为电池充电。在直连电路导通,且在接收到切换信号的情况下,控制升压电路导通后,控制直连电路断开。
