The invention discloses a control circuit, an energy storage power supply and a cable. The control circuit comprises a relay and a switching control circuit, the relay comprises a coil and a contact switch, the coil is used for generating magnetic force when current passes so as to close the contact switch, the switching control circuit is used for adjusting the voltage of the coil, and when the output of the relay is started, the coil receives first voltage so as to ensure that the contact switch generates closing action; when the relay maintains output, the coil receives the second voltage to ensure that the contact switch maintains a closed state, and the first voltage is greater than the second voltage. Thus, in the starting stage of power supply of the relay, the switching control circuit can output large voltage to the coil so that the coil can have enough magnetic force to pull the contact switch to act, and after the contact switch is closed, the switching control circuit can output small voltage to the coil so that the coil can maintain the closed state of the contact switch.
本申请公开了一种控制电路、储能电源和线缆。控制电路包括继电器和切换控制电路,继电器包括线圈和触点开关,线圈用于在电流通过时产生磁力以使得触点开关闭合,切换控制电路用于调节线圈的电压,在开启继电器输出时,线圈接收第一电压以保证触点开关产生闭合动作,在继电器维持输出时,线圈接收第二电压以保证触点开关维持闭合状态,第一电压大于第二电压。如此,在继电器供电的开始阶段,切换控制电路可以向线圈输出较大的电压,以使得线圈有足够的磁力以拉动触点开关动作,在触点开关闭合后,切换控制电路可以向线圈输出较小的电压,以使得线圈可以维持触点开关的闭合状态。
