The invention relates to the technical field of automobiles, in particular to a charging and discharging connecting device and an emergency starting power supply, and the charging and discharging connecting device comprises a large-current output circuit, a reverse charging circuit and a controller; one end of the large-current output circuit is connected with external load power supply equipment through an electric clamp, and the other end is connected with an internal power supply; the controller is used for sending a power supply enable signal to the large-current output circuit after the electric clamp is correctly connected with external load power supply equipment; the large-current output circuit realizes on-off according to the power supply enable signal so as to control an internal power supply to supply power to external load power supply equipment through the electric clamp; the controller is also used for sending a reverse charging control signal to the reverse charging circuit; and the reverse charging circuit is used for enabling external load power supply equipment connected with the electric clamp to charge the internal power supply according to the reverse charging control signal. Therefore, the problem that the emergency starting power supply needs to be charged independently in the prior art can be effectively solved.
本申请涉及汽车技术领域,尤其涉及一种充放电连接装置及应急启动电源,包括:大电流输出电路、反充电路和控制器;大电流输出电路的一端用于通过电夹连接外部负载供电设备,另一端用于连接内部电源;控制器用于在电夹正确连接外部负载供电设备后向大电流输出电路发送供电使能信号;大电流输出电路根据供电使能信号实现自身的通断,以用于控制内部电源通过电夹向外部负载供电设备供电;控制器还用于向反充电路发送反充控制信号;反充电路用于根据反充控制信号使电夹连接的外部负载供电设备向内部电源充电。由此,本申请可以有效解决现有技术中应急启动电源需要单独对其进行充电的问题等。
