Description
Technical field
The utility model is related to a kind of automatic constant current constant-voltage charge systems for electric car.
Background technology
Electric car be using accumulator driving motor work, for meet existing electric car supply voltage requirement, it is necessary to by
Multiple accumulators are composed in series battery pack and power to motor, and in actual use, the loss rate of multiple accumulators differs
Sample easily generates voltage difference, and when voltage difference is excessive, the output of battery pack can be unstable, causes motor vibrating, it is generally recognized that this
When be exactly battery electric quantity deficiency, but the actually electricity of part accumulator also enough electric cars traveling a period of time, together
When low battery in order to prevent accumulator feeding cause entire battery damage, it is also necessary to charge, but for high electricity
Accumulator is not substantially discharged and frequent charge can cause accumulator because bad memory function causes maximum electricity to reduce, frequency
Numerous charging also results in the service life quick failure of accumulator, influences the service life of battery pack, is generally up in actual use
Mileage and usage time are used less than calibration.
The content of the invention
In order to solve the deficiencies in the prior art, the utility model, which provides, a kind of can realize battery pack automatic constant-pressure
The automatic constant current constant-voltage charge system for electric car of constant current.
To achieve the above object, the utility model uses a kind of automatic constant current constant-voltage charge system for electric car, bag
Driving motor, generator, battery pack, controller are included, driving motor is connected with generator, and generator is electrically connected with battery pack
It connects, battery pack is electrically connected with the controller, and controller is electrically connected with driving motor, and the battery pack includes multiple storages being sequentially connected in series
Battery, the generator are electrically connected with the controller.
The utility model is further arranged to be provided with chain wheel on the driving motor, and generator passes through sprocket wheel and chain wheel
Connection realization is connected with driving motor.
The utility model is further arranged to be provided with silicon stack on the generator, generator by silicon stack and controller and
Battery pack is electrically connected.
The accumulator that the utility model is further arranged to series connection in the battery pack is 3~7.
The beneficial effects of the utility model are to install a generator additional on the original driving motor of electric car to controller
With it is battery-powered, make electric car that driving motor power consumption be generated a part of kinetic energy in the process of moving and be converted by generator
Electric energy feeds driving motor by the way that controller is counter, and in electric motor vehicle sliding, generator will slide potential energy as electric energy, because not
Driving motor is needed to provide kinetic energy, the electric energy that generator generates does not enter controller, but enters storage of the battery pack to low battery
Battery charges, and makes to realize constant pressure and flow between the accumulator in battery pack, is slided because always being had during electric car traveling,
Therefore the constant pressure and flow of accumulator is automatic, and user can also make somebody a mere figurehead driving wheel, pass through the electrical energy drive generator of battery pack
Manual constant pressure and flow is realized to the storage battery power supply of the low battery in battery pack.The utility model passes through filling again during traveling
Electricity reallocates to the accumulator electric-quantity in battery pack, realizes the automatic constant-pressure constant current between accumulator, improves each storage
The utilization rate of battery, the distance travelled for not only increasing electric car also improve the service life of accumulator.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model specific embodiment.
Specific embodiment
As shown in Figure 1, specific embodiment of the utility model is a kind of automatic constant current constant-voltage charge system for electric car
System, including driving motor 1, generator 3, battery pack 5, controller, is provided with chain wheel 2, generator 3 passes through chain on driving motor 1
Wheel is connected with chain wheel 2, silicon stack 4 is provided on generator 3, generator 3 is electrically connected by silicon stack 4 with controller and battery pack 5 respectively
It connects, powers to controller and battery pack 5, battery pack 5 includes multiple accumulators 6 being sequentially connected in series, controller and 1 electricity of driving motor
Connection driving driving motor movement, the accumulator 6 of the interior series connection of battery pack 5 is 4.
The course of work of the utility model is during electric car traveling, and battery pack is to controller for electric drive driving electricity
Motor-driven work makes electric car advance, and driving motor drives electrical power generators to power to controller simultaneously；In electric motor vehicle sliding, driving
Motor is not required controller power supply that can just rotate, and drives electrical power generators, the electricity at this time generated is filled with battery pack, to low-voltage
Accumulator charge, balance the voltage between different batteries, realize constant pressure and flow between accumulator, due to total in the process of moving
It is to have coasting-flight phase, therefore always can carries out constant pressure and flow to accumulator, so as to fulfill automatic constant-pressure constant current；If it is still expert at
Short of electricity phenomenon occurs during sailing, short of electricity phenomenon actually appears one accumulator low battery in battery pack, can adopt
With emergency power generation method by supportting upper electric vehicle double-support, drive generator to battery pack charging come to low battery by driving motor
Accumulator, which charges, realizes constant pressure and flow, increases distance travelled, through experiment, after the electric bicycle drive wheel that soars, accelerates 30 by handle
Second, it, can after repeatedly charging repeatedly for old accumulator to 5 kilometers can be run immediately after the accumulator constant pressure and flow of low battery
To activate increasing storage battery service life.
