It needs, one or more groups of secondary power battery packs 102 is packed into secondary power battery storehouse 103, secondary power battery pack 102 can be by user
Purchase or lease, in such a mode, electric automobile during traveling electric power is provided by secondary power battery pack 102 completely, when secondary power battery
It, can be by replacing secondary power battery pack 102 to save charging resource and charging time, to keep away after 102 electric quantity consumptions of group
Exempt from or mitigate user drive over a long distance in continuation of the journey worry, in case of emergency, can also be in the electric quantity consumption of secondary power battery pack 102
After switch to 101 drive mode of active force battery pack.
For secondary power battery charging drive mode: when the electricity of active force battery pack 101 is low, secondary power electric can be packed into
Pond group 102, while using the secondary power supply of power battery pack 102 traveling, by secondary power battery pack 102 to active force battery pack
101 synchronous chargings；
In such a mode, secondary power battery electric power converter is by secondary 102 power output of power battery pack to motor driven system
System, while by part power output to active force battery electric power converter, active force battery electric power converter receives from secondary dynamic
The electric energy of power battery electric power converter charges to active force battery pack 101, and active force battery electric power converter is to motor driven system
For system without output, motor driven systems receive the electric energy from secondary power battery electric power converter, and export to driving motor 106,
Drive electric automobile during traveling；This mode can meet the charging of active force battery pack 101 under the premise of not influencing normally travel
Demand is suitable for low-power and travels road conditions.Active force battery charge time can be further saved.
For the common drive mode of major-minor power battery pack 102: when active force battery pack 101 and secondary power battery pack 102
Electricity is enough in use, (as when heavy grade road surface) when this mode can be used to cope with complex road condition；
In such a mode, active force battery electric power converter and secondary power battery electric power converter are by power output to electricity
Machine drive system, for secondary power battery electric power converter to active force battery electric power converter without output, motor driven systems can be with
With maximum power output electric power to driving motor 106, guarantee the high-power output of 106 machine of driving motor；This mode major-minor power electric
Pond group 102 provides driving power jointly, to guarantee 106 output power of driving motor, prevents power battery overdischarge, improves power
Battery.
For secondary power battery parking powering mode: under dead ship condition, when user selects this mode, full-vehicle control system
System 105 controls secondary power battery electric power converter to active force battery electric power converter according to the state of active force battery pack 101
Lasting output, active force battery electric power converter adjust charging current according to the state of active force battery pack 101, when active force electricity
When the electricity of pond group 101 reaches requirement or when the electricity of secondary power battery pack 102 is lower than 20% electricity, whole-control system 105
It controls secondary power battery electric power converter and stops output；
When charging pile resource scarcity, user can be during parking by way of renting secondary power battery pack 102
Active force battery pack 101 charges, and after charging complete, connects between disconnecting major-minor power battery pack 102 by whole-control system 105
The case where connecing, being suitable for user's daily commuting region charging pile inadequate resource occupies charging pile resource without long-term.
For normal charging mode: when electric car accesses external charging power supply by charger, will enter and commonly fill
Power mode；
In such a mode, whole-control system 105 is according to 101 state of active force battery pack monitored and secondary power battery
102 states of group will input active force battery electric power converter by the external electric energy of charger input, to active force battery pack
101 charge, and when monitoring secondary power battery pack 102, and when secondary 102 electricity of power battery pack is discontented, charger is inputted
Part electric energy be input to secondary power battery electric power converter, synchronize to secondary power battery pack 102 charge.Synchronous for secondary power
When battery charges, the charging time is relatively long.
