What is controller of electric car, how to choose when buying?
Choice of electric cars:First, the choice of brand, after-sales service credibilityThe brand is a symbol of quality, different brands of the quality level is uneven, consumers must choose the authority of the Department, and proven reliable quality, low repair rate, good customer service service, high reputation of the brand.
Electric vehicle controller is used to control the electric motor to start, run, stop, speed, as well as the core and other electronic devices electric vehicle control device, it is like a car's brain, is an important part of electric vehicle. Electric vehicles currently includes two electric bicycles, motorcycles, electric tricycle, electric tricycle, electric vehicle with four wheels, car batteries, electric vehicle controller because of different models and different performance and features.
Optional configuration: the four major components of electric vehicle are: motor, battery, controller, charger.1, in the drive way, should consider synthetically, choose the small loss, low energy consumption, high efficiency of the way; the motor is divided into three kinds: high speed brush motor, brush low-speed motor, brushless motor. High speed motor, high efficiency, large power, good climbing ability, suitable for long distance travel. Brush speed motor of low efficiency, large power consumption, mileage is shorter, the motor is suitable for flat pavement, the rider is light, riding climbing can help consumers. The brushless motor needs current commutation, the controller is easy to burn, and the reliability is transferred from the motor to the controller. High speed is nearly twice the price of low speed motor.2, battery according to voltage is divided into: 36V, 48V, 64V, etc., according to the capacity is divided into: 10Ah, 12Ah, 14Ah, 20Ah, etc., according to the type is divided into: lead-acid, nickel hydrogen, lithium batteries. Battery is a combination of voltage and capacity, some cars with 36V12Ah, some cars with 48V12Ah or 20Ah, and some cars with 64v20Ah, between them in capacity, mileage, price is very different. Buy electric bicycles must be clear: as a means of commuting, do not ask too high.
