Description
Technical field
It the utility model is related to a kind of pure electric automobile.
Background technology
In order to reduce pure electric automobile on-vehicle battery useful load as far as possible, the continual mileage grown as far as possible is wished again, it is various
The pure electric automobile with quick charging and conversion electric function of type arises at the historic moment.For this kind of pure electric automobile set parking lot and
Fill, change electric facility and generally have the following two kinds：
First, power mode is changed merely.After pure electric automobile enters parking lot, it is parked in and is changed equipped with special on the parking stall of electromechanical,
Special electromechanical of changing removes vehicle-mounted accumulator box from car body, is reloaded into oneself fully charged battery case, and vehicle sails out of this
Reserved Parking, fill, change electric process completion.The battery case removed is placed on charging room charging.
Second, a charging pile is arranged on each parking stall in parking lot, vehicle is parked in any one parking stall can
Voluntarily charge.
But pure electric automobile enter parking lot prepare the time of charging and in parking lot residence time be all it is random,
Above two fills, changes electric facility just show do not adapt to this randomness, the drawbacks of.
The first is arranged in order to meet that the special car for changing electromechanical will be left as early as possible by quickly continuously changing electric, vehicle
Position, next chassis is allowed to enter.If being not concerned with staying for some time in parking lot to vehicle can be with the profit of the time of boost charge
With.Oneself considerable fully charged battery case is just must be equipped with so in parking lot.
Second of arrangement considers the randomness of this parking, but master control in the charging pile arranged on each parking stall and field
The transmission of the parameter signal such as voltage, electric current, electricity, temperature and power recharge cable in the charging process that must be laid between platform, this
Very big investment can undoubtedly be increased.Also due to vehicle stop into randomness, these transmission cable network usages again it is very uneven
Weighing apparatus, cause investment utilization rate low, charging and conversion electric cost increase.
In order that into parking lot pure electric automobile can according to oneself in parking lot residence time, selection immediately
Change battery case still first can remove wait boost charge by battery case, wait and again load onto battery case when rolling parking lot away from, fully
Potentiality of the digging vehicle residence time to battery case electric energy supplement.
But how to solve after vehicle mounted dynamic battery case is removed, vehicle sails out of special electric car position of changing to other parking stalls
Go.Current most pure electric automobiles are all only equipped with one group of battery case for being used to drive, if the electricity in this Battery pack case
It can exhaust or be removed, vehicle can not just be run.It is thus impossible to adapt to matching charging and conversion electric network arrangement.
The content of the invention
The utility model aims to provide a kind of pure electric automobile for reducing and changing cost in electric process.
In order to solve the above technical problems, the technical scheme of pure electric automobile is as follows in the utility model：
Pure electric automobile, including car body, car body is interior to be provided with the control circuit for being used for controlling motor to operate, control circuit
Two power interfaces are provided with, the first power interface is conductively connected boosting battery case of the static connection in car body, second source
Interface is conductively connected the dynamic main battery case being connected in car body, and the capacitance of main battery case is more than the electric capacity of boosting battery case
Amount, and main battery case and boosting battery case are using the voltage such as specified.
The gusset of car body is provided with window to be opened/closed, main battery case can pull be arranged in car body, main battery case and
Window is oppositely arranged.
DC charger is serially connected between first power interface and second source interface.
It is parallel with one another between first power interface and second source interface.
The controller for controlling the first power interface and second source interface break-make, controller are additionally provided with control circuit
Have when main battery box installed enters and does not accelerate cut off boosting battery case and connect main battery case first state, main battery case from
The second state of second source interface and connection boosting battery case is cut off when car body takes out and when main battery box installed enters and accelerates
It is also turned on the third state of main battery case and boosting battery case.
The beneficial effects of the utility model are：
The reserve of electricity of boosting battery case is after main battery case needs to change electricity and removes, to utilize the electricity in boosting battery case
Can, distance that vehicle must also move in parking lot, disengaging parking lot gradient situation determination, different parking environments have compared with
Big difference, with the Redundancy Design of electricity in boosting battery case, to meet required parking environment, cost in electric process is changed in reduction.
