Judgment step S120 is accelerated to judge whether electric vehicle is in acceleration mode if meeting switching condition.
When electric vehicle and mobile energy storage device meet above-mentioned switching condition, such as vehicle power module has been lost at this moment
Electricity, the entire car controller of electric vehicle need to judge whether electric vehicle is in acceleration mode.Specifically, entire car controller passes through
The variation of input current in the driving motor of current sensor detection electric vehicle is regarded as if electric current increases over time
Electric vehicle is in acceleration mode；If electric current reduces at any time, then it is assumed that electric vehicle is not in acceleration mode and is in and slows down
State；If electric current is constant at any time, then it is assumed that electric vehicle is not in acceleration mode and is in and drives at a constant speed state (electric current > 0)
Or halted state (electric current 0).
Timely switch step S130 uses the standby electricity in mobile energy storage device if electric vehicle is not in acceleration mode
Source module replaces vehicle power module and powers from it to the electricity system of electric vehicle.
If electric vehicle is not at acceleration mode, the handoff procedure of power supply can be entered, there are many kinds to realize for the process
Mode, different application combinations, the present embodiment only introduce a kind of simple and practical process, recommend the shape extremely low in parking or speed
Switch under state.
Firstly, the entire car controller of electric vehicle can control vehicle power module into lower electric current journey, the lower electric current journey
It include: first to disconnect the negative DC contactor of vehicle power module, then disconnect the positive DC contactor of vehicle power module.Its
Secondary, standby power supply module 21 includes: elder generation into process is powered under the control of the vehicle control unit controls module 22 of electric vehicle
It is closed the positive DC contactor of standby power supply module 21, recloses the negative DC contactor of standby power supply module 21, is completed
Entire power up.In addition, switch step is other than comprising above-mentioned lower electric process and power up also comprising precharge in time
Process, the preliminary filling cross process and execute prior to power up but be later than lower electric process execution.Wherein, the pre-charge process is ability
The conventional process in domain repeats no more for the sake of saving length.
In the present embodiment, the combination control method of the electric vehicle of the utility model and mobile energy storage device may also include
Positioned at condition judgment step S110 and accelerate the switch prompting step S111 between judgment step S120, the switch prompting step
If S111 includes: the vehicle power supply power shortage of electric vehicle, the power supply switch prompting function of the prompting device in electric vehicle is opened
Can, prompting device includes lamp, electronic curtain or loudspeaker.For example, when meeting above-mentioned switching condition, the full-vehicle control of electric vehicle
Device issues instrument " power supply switch prompting " signal, lights " power supply switch prompting " signal lamp in instrument, or in instrument display screen
Upper display switching signal or prompt statement.Driver no longer controls after receiving " power supply switch prompting " signal under normal circumstances
Electric vehicle accelerates, but driver may also ignore the signal, and electric vehicle will continue in acceleration mode.
In the present embodiment, the combination control method of the electric vehicle and mobile energy storage device may also include postponement switching step
Rapid S130 '.The postponement switch step S130 ' is forced if including: that electric vehicle is in acceleration mode, is persistently reduced vehicle mounted electric
The output power of source module uses the backup power source of mobile energy storage device when the output power of vehicle power module is zero
Module replaces vehicle power module and powers from it to the electricity system of electric vehicle.It is to be noted that forcing drop driving function
Rate needs a smooth process, cannot limit too fast in order to avoid driver can not react, and causes danger.
In the present embodiment, the combination control method of the electric vehicle and mobile energy storage device may also include to be located at and cut in time
It changes step S130 and postpones the successful switch prompt step S140 after switch step S130 ', the successful switch prompt step
S140 includes: the successful switch prompt facility for opening the prompting device in electric vehicle, and prompting device includes lamp, electronic curtain or loudspeaking
Device.For example, entire car controller issues instrument " power supply switches successfully instruction " signal after power supply handover success, light in instrument
" power supply switch successfully instruction " lamp, or show the handover success signal or prompt statement on instrument display screen, so far complete
Entire switching control process.
In the present embodiment, the combination control method of the electric vehicle and mobile energy storage device may also include not switch step
In S120 ', further includes: if electric vehicle and mobile energy storage device are unsatisfactory for above-mentioned switching condition.
In the present embodiment, stop executing if a period of time that entire car controller knows following situations and accelerate judgment step S120
Following steps: the power shortage of standby power supply module 21 can not support electric vehicle normally travel or limit power traveling；Backup power source mould
Block 21 is faulty, can be unsatisfactory for the demand of the electricity system of electric vehicle；Or driver wants to retain standby power supply module 21
Electricity.
The combination control method of electric vehicle provided by the utility model and mobile energy storage device passes through mobile energy storage device
Control module and the entire car controller of electric vehicle jointly control, realize mobile energy storage device standby power supply module and
Switching between the vehicle power module of electric vehicle, simple and easy, switching time is short and safe and reliable.
