Description
Technical field
The utility model relates to electronlmobil, has particularly related to a kind of extended-range power battery device.
Background technology
Current existing electronlmobil is because be subject to the restriction of battery energy density, battery cost and car load installing space, car load course continuation mileage is general all at about 100-200km, the demand that the long distance of chaufeur is driven can not be met, in addition, when after running down of battery, if car load adopts charging modes, there is the problem that battery-charging station is few, charging duration is long; If but electric mode is changed in employing, and there is construction electrical changing station needs the problem dropping into more capital.
Summary of the invention
The utility model, for above-mentioned shortcoming, provides a kind of extended-range power battery device.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Extended-range power battery device, comprises the driver module driving battery-driven car to travel, it is characterized in that:
Also comprise controller, main battery module and emergency battery module, main battery module comprises main battery and master battery management system, main battery connects the input end of main relay, and the mouth of relay is connected with driver module, and master battery management system connects the control end of relay;
Emergency battery module comprises emergency battery and emergency battery management system, and emergency battery connects the input end of duplicate relay, and the mouth of duplicate relay is connected with driver module, and emergency battery management system connects the control end of duplicate relay;
Master battery management system is connected with controller respectively with emergency battery management system.
The battery management system (BMS) of electronlmobil is the important tie connecting vehicle mounted dynamic battery and electronlmobil, and its radical function comprises: battery physical parameter Real-Time Monitoring; Battery status is estimated; Inline diagnosis and early warning; Charge and discharge and preliminary filling control; Balanced management and heat management etc.
As preferably, master battery management system is connected by CAN with controller respectively with emergency battery management system.CAN Performance And Reliability is high, and data communication is real-time.
As preferably, between master battery management system and main relay, between emergency battery and duplicate relay, be equipped with wire fuse.Wire fuse is when current anomaly is elevated to certain height and temperature, and electric current is cut off in self fusing, thus plays the effect of protective circuit safe operation.
As preferably, controller is micro controller system.
As preferably, between driver module and main battery, be also provided with switch.Chaufeur can manual cut-off switch, and main battery is stopped power supply.Close a switch again after emergency battery electricity exhausts.
The utility model is owing to have employed above technical scheme, there is significant technique effect: when emergency battery is arranged on after on battery-driven car, battery-driven car POST, controller and master battery management system, emergency battery management system carry out communication by CAN communication agreement, after controller judges that the voltage of emergency battery is greater than the voltage of main battery, controller sends a signal to master battery management system, and master battery management system controls main relay and disconnects, and battery-driven car is powered by emergency battery.The utility model when former car change is measured less, can actv. solve batteries of electric automobile electricity lower time charging difficulty and the problem grown of charging duration, considerably increase the course continuation mileage of electronlmobil.
