The beneficial effects of the utility model are: whole fast-assembling and the quick-release of having realized the power battery of electric vehicle group, overcome the drawback that once to change some battery module battery cases when battery is changed in electric motor car, shortened the replacing battery time, improved replacing efficient, provide possibility for popularizing electric motor car.Solved the safety problem that lithium battery charges on vehicle, and maintained easily, changed convenient, fast.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is a structure front view of the present utility model.
Fig. 2 is a structure right side view of the present utility model.
Embodiment
Embodiment has as shown in Figures 1 and 2 installed 90 3.2 volts ferric phosphate aluminum cell in this battery case, be equipped with battery management system, a pressure cooling fan 7 and the various auxiliary of a cover.
---battery management system (BMS)
Battery management system comprises 3, four of primary control box from control box 4 in the present embodiment, and some auxiliaries.
1, primary control box 3 and carry out communication by the RS485 bus between the box 4 from control in the present embodiment carries out communication by the CAN bus between primary control box 3 and automobile instrument, charger and the electric machine controller.
Vehicle has been equipped with an integrated instrument of special electric automobile, is installed on the bridge instrumentation platform, in order to every information of showing battery, charger and motor and the indication of reporting to the police is provided.
Main control module in the primary control box 3 is in order to handle from detected voltage, temperature and current signals such as control module, current sensor, temperature sensors.Relevant information on the one hand gives electric automobile integrated instrument by the CAN bus after treatment, will be used for the operation of controls 6 cooling fans and stops through temperature signal later on the other hand, and the temperature in the control battery case is in the scope of setting all the time.
2. from control box 4 voltages of maximum 30 batteries of monitoring in real time, monitoring in real time is installed in the temperature information that temperature sensor on the battery electrode column is monitored this this Battery pack of managing from the control module in real time.
3. except that the integrated instrument of electric automobile, other BMS assemblies are installed in power brick inside, primary control box 3 is crossed the wiring harness junction block 5 that is installed in the management system auxiliary mounting panel 9 in the Battery case and is gone out the CAN signal, the CAN signal is divided into three the tunnel, one gives the integrated instrument of electric automobile, one the tunnel gives charger, and one gives electric machine controller.
Power brick when in use, the 24V power supply of BMS and fan electromotor is provided by vehicle-mounted DC-DC,
In the time of charging, power supply is by the 24V power supply power supply of the auxiliary output of charger.
---force cooling fan
The temperature signal of forcing cooling fan 6 battery management systems to provide is controlled its work, reach 6 beginning of fan pressure blowing cooling when opening temperature, temperature is reduced to fan 6 moving stopping when stopping temperature, make battery case inside reach the balance of heat by air cooling way, temperature is controlled in the scope of battery operate as normal.
In the present embodiment, when the temperature that detects certain temperature monitoring point in the battery module when battery management system (BMS) surpassed 40 ℃, management system control cooling fan 6 was started working, and when temperature was reduced to 20 ℃, cooling fan 6 quit work.
In the present embodiment, do not need the universal battery management system is done bigger improvement, but need in the management system the temperature monitoring system output monitoring to cooling fan 6 operation and the control signal of telecommunication that stops, the electromagnetically operated valve of this control signal of telecommunication by cooling fan 6, the operation of control cooling fan 6 motors and stopping.When battery temperature is higher than the motor operating temperature of setting, the management system output signal of telecommunication, electromagnetically operated valve is connected, the operation of fan 6 motors; When the motor that is lower than setting stopped temperature, management system stopped the output operation signal of telecommunication, and electromagnetically operated valve disconnects, and fan 6 motors stop.
---battery altering
The set bolt 10 of battery case is arranged in the side of battery case, when battery management system prompting battery is used quantity not sufficient, can change battery.Manually unclamp battery set bolt 10, deenergization wire harness, management system communication wire harness adopt lifting appliance by the battery case suspension ring 2 integral type battery case of slinging, integral replacing battery case.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
