Pure electric system of logistics vehicle

The pure electric logistics vehicle system developed by Wanrun, can adapt to the complex road conditions of various major cities, all kinds of climate conditions. The self-producing system includes the driving motor, the pure electric vehicle controller, the three in one controller (driving motor controller, high voltage distribution box, DCDC).

（1）Advantages of direct drive without driving shaft:

1. Suitable for Mini van & Mini truck.

2. High speed ratio of rear axle and low cost of power assembly.

3. Large batch in production and sales, mature and reliable.

4. The motor with small size and light weight.

（2）Advantages of direct drive with driving shaft:

1. Stable and reliable electric control system.

2. The system with high efficiency in cooling and strong overload capacity. It can meet the overload operation condition of the vehicle.

3. Adopts permanent magnet synchronous motor (PMSM), integrate the auxiliary parts controller, convenient for installation and arrangement, high in efficiency, small in vibration and low in noise.

（3）The scheme with DAT transmission

Advantages

1. Effectively solves the problem of vehicle that its’driving mileage at high speed is much lower than that of medium speed.

2. Reducing the work of lithium battery in high power discharge condition.

3. Improve vehicle dynamic performance.
