What electric wagons are there in Dezhou, Shandong Province?

There are three electric wagons in Dezhou, Shandong Province, namely, Fulu, Baoya and Reading, which are located in Dezhou Development Zone and Lingcheng Development Zone respectively.

Four-wheel electric vehicles refer to pure electric vehicles with a top speed of less than 50 kilometers per hour. Four-wheel electric vehicles include electric sightseeing bus, electric golf cart, electric patrol car, electric sanitation vehicle, electric transport vehicle, electric tractor, electric engineering vehicle and specially modified electric vehicles.

major component

The performance of a four-wheel electric vehicle is bound to be related to the quality of battery, electronic control, motor and charger.

battery

Lead-acid batteries are mostly used in four-wheel electric vehicles. Some four-wheel electric vehicles also use lithium batteries as power sources. As the only power source of electric vehicles, the quality of batteries directly affects the use of four-wheel electric vehicles.

Electrical control

Electronic control is divided into separate excitation, series excitation and permanent magnet motor speed controller according to different motors.

The main features of electronic control are:

First, it can prevent the flying car from starting. When the vehicle starts, if the controller detects that the pedal input signal is greater than 20%, it will trigger the HPD controller to prohibit the output.

Second, the operation sequence protection function (SRO) when starting the vehicle.

Thirdly, the microprocessor performs power-on self-test and continuous diagnosis during operation. If there is a fault, the controller will immediately stop the output, thus fully protecting the operator and the vehicle.

Fourth, the controller has the function of anti-sliding, which automatically detects the state of the vehicle. When it is found that the vehicle is parked (the electric door lock is closed), it will automatically perform electric braking when taxiing.

Most of the electronic controls used in four-wheel electric vehicles are imported electronic controls.

Different electronic control devices will have slightly different functions and use different environments.
