The variation of power port voltage value determines the charged state of charging gun and the connection status of the second battery pack.Wherein, judge charging gun
Charged state namely judge whether charging gun is connected to charge port, judge that the connection status of the second battery pack namely judges
Whether the second battery pack is connected to charge port, and specifically, the connection of charge port includes three kinds as shown in Table 1:
Table one
| Charging gun | Second battery pack |
| It is not connected | It is not connected |
| It is not connected | Connection |
| Connection | Connection |
When judging the second battery pack for connection status, namely when the second battery pack is connected to charge port, the second battery
Management system controller controls electronic switch closure；When judging the second battery pack for not-connected status, namely when the second battery
When packet is not connected to charge port, the second battery pack management system controls electronic switch and disconnects.Therefore, when different equipment is connected to
When charge port, there is also differences for the variation of charge port voltage value.Therefore, using the first controller of battery management system to charging
The variation of mouth voltage value is detected, and the connection shape of the second battery pack is judged according to the variation of the charge port voltage value detected
The charged state of state and charging gun.

Resistance.
When the second battery pack and/or charging gun are connected to charge port, the voltage of interior each test point can be sent out in the device
It is raw to change, and the changing rule of the voltage value of each test point be it is fixed, the test point in the present embodiment includes charge port
And the second end of controllable switch, then it can use the first controller of battery management system and the control of the second battery management system
Device detects the variation of corresponding test point voltage value, judges the connection of the second battery pack according to the variation of test point voltage value
The charged state of state and charging gun.Wherein, the first controller of battery management system is used to detect the change of charge port voltage value
Change, the second controller of battery management system is used to detect the voltage value of the second end of controllable switch.
Specifically, the second controller of battery management system is used for: the second terminal voltage value by detecting controllable switch judges
The connection status of second battery pack.In practical application, the second controller of battery management system is used not only for judging the second battery
The connection status of packet, it may also be used for monitor physical parameter, estimated battery state, inline diagnosis and early warning, the control second of battery
Battery pack charged, is discharged and preliminary filling etc..
First controller of battery management system is further used for:
When detecting charge port voltage value is the first voltage value, determine that the second battery pack is not-connected status, charging gun
For uncharged state.When the second controller of battery management system detects that the second battery pack is not connected to charge port, the second battery
Management system controller controls controllable switch and disconnects, if the first controller of battery management system detection charge port voltage value is first
Voltage value determines that the second battery pack is not-connected status.
When detecting charge port voltage value is second voltage value, determine that the second battery pack is connection status, charging gun is
Uncharged state.When the second battery pack is connected to charge port, the second controller of battery management system controls controllable switch closure, if
