During non-charged state, it is to ensure that electric automobile energy normally travel reaches charging pile position, if the dump energy of battery bag is less than
10, all branches in 1003 to the 5th branch road 1005 of the 3rd branch road need to be disconnected, namely is closed whole on electric automobile
Overall height voltage device, thinks that automobile retains certain electric energy.
When battery bag charge mode for fill state soon when, due to the dump energy in battery bag by the way of filling soon it is little
Charging current when the 80 percent of the battery capacity of battery bag is larger, is easily caused battery bag heating, if now the 3rd
1003 to the 5th branch road 1005 of branch road is connected with battery bag, namely car load high tension apparatus, still in work, the discharge current can also be led
Battery bag heating is caused, when the temperature of battery bag reaches certain numerical value, the service life of battery bag can be caused to shorten, therefore filled soon
State, if the dump energy of battery bag is less than the 80 percent of battery bag battery capacity, need to be controlled by master controller 18
3rd branch road, 1003 to the 5th branch road 1005 is disconnected with battery bag.
When the charged state of electric automobile is trickle charge state, if the dump energy of battery bag is reducing or is keeping not
Become, it was demonstrated that be less than or equal to the discharge power of battery bag for the power that battery bag charges, now, battery bag cannot be charged,
To ensure the charge efficiency of battery bag, all or part of branch road and electricity in 1003 to the 5th branch road 1005 of the 3rd branch road need to be disconnected
The connection of Chi Bao.
The connection of the arbitrary branch road in 1001 to the 6th branch road 1006 of tie point and battery bag is controlled in master controller 18
When state changes, master controller 18 can Jing low-voltage lines and car load network send this to the human-computer interaction device of electric automobile
The handover information on road, to avoid user alarmed because of the unexpected state change of high-voltage device part.
As shown in figure 1, in embodiments of the present invention, high pressure electric appliance box also includes current sensor 19, current sensor 19
It is arranged on the main line 100 between the positive relay 2 of master and 1001 to the 6th branch road 1006 of tie point, for monitoring main line 100
On current information.
