Technical field
The utility model relates to electrical vehicular power control devices, and in particular to a kind of dynamical system of electric car.
Background technique
Electric car refers to using vehicle power supply as power, with motor driven wheels travel, meets road traffic, security legislation
The vehicle of requirements.Electric car is had an optimistic view of extensively by following advantages prospect, and the small electric car of 1. environmental pollutions used
Exhaust gas will not be generated in journey, not there are problems that atmosphere pollution compared with orthodox car.2. noiseless, noise is low, this is
The most intuitive feature of electric car.Automobile noise has become a kind of more serious pollution in present big city, reduces noise
Pollution is also the test to auto industry from now on.3. high efficiency this be the most significant feature of electric automobile energy use aspects.?
In city, vehicle driving is more on road, and frequently encounters traffic lights, and vehicle constantly must stop and start.For passing
It unites for fuel-engined vehicle, electric vehicle is in parking, it is not necessary to allow motor to dally, can greatly improve the service efficiency of the energy, subtract
Few air pollution.4. structure is simple, easy maintenance, durable, this is most light in terms of electric car operating cost
Point.Compared with conventional fuel oil automobile, the easy manipulation of electric car, structure are simple, and operating transmission parts are compared to less, and no replacement is required
Machine oil, oil pump, silencing apparatus etc., without addition cooling water.Maintenance amount is few.If there is good battery, it
Service life is also than fuel oil vehicle commander.5. use scope is wide, not influenced this by local environment is another advantage place of electric car.?
Special occasions, such as stuffy, winter low temperature place or the place of High aititude anoxic, electric vehicle driving are entirely unaffected by.
The dynamical system power resources of existing electric car cause electric car row since battery energy storage is limited in battery
Journey is shorter.
Utility model content
To solve the above-mentioned problems, the electric powered motor system that a kind of structure is simple, and easy to use, power-on time is grown is provided
System, the utility model devise a kind of dynamical system of electric car.
The utility model the specific technical proposal is: a kind of dynamical system of electric car, including battery, header box, electricity
Source switching switch, ECU and motor driver, the battery include at least the first battery and the second battery, the first battery or second
Battery is correspondingly connected on header box, and the circuit between first battery or the second battery and header box switches equipped with power supply
Switch, the power change-over switch are correspondingly connected on ECU；The header box connects driving motor by motor driver.
Preferably, the power change-over switch is connected on ECU by CAN bus.
Further, super capacitor is connected on the circuit between header box and motor driver.
Further, the driving motor is correspondingly connected with before vehicle on bridge or rear axle by speed changer.
Further, the first battery or the second battery are equipped with the monitoring cell electricity quantity device of connection ECU.
Advantageous effects: two groups of batteries of setting, it is ensured that automobile stream time is double, guarantees electric car
Operating range.
