An electrical coupling circuit, comprising:
- a first switch module comprising a first main switch and a first auxiliary switch, wherein two ends of the first main switch and two ends of the first auxiliary switch are connected to a first electrode of a power source and a first input end of a load respectively;
- a second switch module comprising a second main switch and a second auxiliary switch, wherein two ends of the second main switch and two ends of the second auxiliary switch are connected to a second electrode of the power source and a second input end of the load respectively;
- an energy storage module, wherein two ends of the energy storage module are connected to the first input end and the second input end of the load respectively;
- and
- a control module connected to the first input end of the load, the first switch module and the second switch module;
- wherein the control module is configured to turn on the first auxiliary switch and the second auxiliary switch to perform a pre-charging process for charging the energy storage module, wherein when the control module determines that a voltage of the first input end fails to reach an initial voltage value within a first predetermined time or the voltage of the first input end reaches the initial voltage value but fails to reach a predetermined voltage value greater than the initial volage value within a second predetermined time, the control module is configured to turn off the first auxiliary switch and turn on the first main switch, wherein the control module determines that the voltage of the first input end fails to reach the predetermined voltage value within the second predetermined time, the control module is configured to turn off the second auxiliary switch and turn on the second main switch so as to continue the pre-charging process, wherein when the voltage of the first input end fails to reach the predetermined voltage value within the second predetermined time, the control module is configured to turn off both the first main switch and the second main switch, and generate an abnormal signal standing for a reverse-connection state.
An electrical coupling method, comprising:
- controlling a connection state of a first electrode of a power source and one end of an energy storage module by a first main switch and a first auxiliary switch connected to each other in parallel;
- controlling a connection state of a second electrode of the power source and another end of the energy storage module by a second main switch and a second auxiliary switch connected to each other in parallel, wherein two ends of the energy storage module are connected to a first input end and a second input end of a load respectively;
- turn on the first auxiliary switch and the second auxiliary switch to perform a pre-charging process for charging the energy storage module;
- turning off the first auxiliary switch and turning on the first main switch when a voltage of the first input end fails to reach an initial voltage value within a first predetermined time or the voltage of the first input end reaches the initial voltage value but fails to reach a predetermined voltage value greater than the initial volage value within a second predetermined time;
- turning off the second auxiliary switch and turning on the second main switch so as to continue the pre-charging process when the voltage of the first input end fails to reach the predetermined voltage value within the second predetermined time;
- and
- turning off both the first main switch and the second main switch, and generating an abnormal signal standing for a reverse-connection state when the voltage of the first input end fails to reach the predetermined voltage value within the second predetermined time.
