AC variable frequency electric vehicle refers to a kind of electric vehicle that uses the vehicle power supply as the power and uses the AC variable frequency motor to drive the wheels. The AC variable frequency electric vehicle adopts the AC variable frequency motor as the driver, which has stable performance, strong anti-overload capability, no burning of the motor, and strong climbing power. The characteristics of smooth start, fast acceleration and low noise during driving make passengers feel more comfortable.

characteristic

1. AC electric vehicles use large-capacity lead-acid sealed batteries as energy storage devices, with good storage and power supply performance, energy utilization rate as high as 92%, stable power supply, short charging time, long vehicle mileage, and no maintenance during use. , No need to add acid and water, the battery has a long service life, generally can be used for three years.

2. The frequency conversion controller adopts the DSP control chip imported from the United States, which is equivalent to microcomputer control, with stable performance and frequency control of electric energy, which is currently the leading technology in China. Low maintenance cost.

3. The AC variable frequency motor is used as the driver, with stable performance, strong anti-overload capability, no burning of the motor, and strong climbing power. When driving, it has a smooth start, fast acceleration and low noise, making passengers feel more comfortable.

Advantage

1. Large torque (strong overload capacity, especially at low speed and large load, it can better meet the climbing and acceleration performance of electric vehicles).

2. Wide speed regulation (higher working speed than DC motors, more in line with the speed performance requirements of electric vehicles) electric vehicles.

3. High efficiency and high density (smaller size, lighter weight and higher efficiency compared with DC motors).

4. Fully enclosed aluminum alloy shell (improves heat dissipation performance and protection level).

5. Compact, small and lightweight (meet the strict requirements of electric vehicles for installation space).

6. Maintenance-free and long service life (basically synchronizing with the service life of the vehicle).
