It is dynamic, change the vehicle of speed with control electric current size.Electric energy is the basis that electric car is capable of normally travel, therefore battery electric quantity
Monitoring is particularly important for electric car, but is constrained to the factors such as volume, cost, and electric car can run into not yet unavoidably
Arrive at the situation of but not enough power supply.
State Intellectual Property Office of the People's Republic of China disclosed entitled " the low electricity of electric car on 03 13rd, 2013
The patent document of amount prompting charging device "（Publication number：CN202798069U）, it is comprising one to export an auditory tone cues
The speaker unit of signal, luminescence unit to export a light cue signal, one to detect the E-Gas
Whether the detector of clean state, and a control unit are in, when detector predicts the E-Gas or electric car of electric car
Electro-motor rotating speed be in clean state after a period of time, control unit can the repeated detection power-supply unit electricity
Amount, and then average electricity is calculated, when low battery is judged as, speaker unit and luminescence unit can be controlled to export prompting respectively
Signal, reminds driver to be charged as early as possible, and the control unit can also limit the power output of the electro-motor of electric car, borrow
To protect power-supply unit.But when electric car is on the way travelled, this scheme can not point out periphery to whether there is charging station,
Driver can not obtain the information that can be charged in time.
The content of the invention
The electric car that the present invention mainly solves present in prior art timely must can not be deposited when on the way travelling to periphery
