Dual power source (APU power generation system + reliable energy storage system) can ensure the normal operation of the vehicle in hybrid mode without external charging conditions, with lower risk of failure, long cruising range and guaranteed attendance rate of over 98%. The full running rate could be over 96%. The reliability is comparable with a traditional vehicle. The finished vehicle meets various extreme environmental operation requirements of four Extremes and one steep (high temperature, high humidity, extreme cold, high altitude and steep slope). Battery capacitors are combined to store energy, and the battery has the same life as the finished vehicle.
Full running rate
Through CAE analysis, the second-generation full loading technology, and the application of high-strength steel, the strength, rigidity and collision safety performance of the finished vehicle are guaranteed to ensure that the vehicle skeleton will not fail for more than 8 years. The finished vehicle adopts lightweight design, taking the 12-meter extended-range plug-in type as an example, the finished vehicle weight is reduced by 10%. The finished vehicle is insulated and the battery compartment is completely physically separated from the passenger area to ensure passenger safety. The vehicle is intelligently insulated, intelligently fault protected, smoke alarmed, and battery fuse designed. Intelligent fire extinguishing system, five layers of protection measures. The electric drive system has an IP67 protection level.

The stepless speed regulation of pure electric drive in the whole working condition makes the driving smoothly and the ride comfortable. The stepless speed regulation pure electric drive and auxiliary system are fully electricized, thus no shifting operation is required, and driving is easy and light. Just like a subway car, the ride would be quiet and comfortable.

Compared with traditional fuel bus, the particulate matter is reduced by 90%, nitrogen oxides by 75%, and dioxide by 50%. When such a car is operated for eight years, it is equals building a 1.84km long urban road green belt.
Reduced particulate matter
Reduced nitrogen oxides
Using products of high-quality battery manufacturers, the battery life is longer. The motor can adjust the working mode according to the actual road conditions, and the motor shaft is more durable.
Working mode adjustable
The lithium battery is equipped with a small-sized, light-weight and high-efficiency dual-motor structure (ISG permanent magnet synchronous motor + TM drive motor), which has strong power; the hybrid electric power can effectively reduce the dependence on fuel and achieve zero fuel consumption of the engine.
Double motor structure
It adopts fast charge lithium battery, which brings high cruising range, large charge and discharge rate, long battery life and fast charging speed. It can be fully charged by dispatching intermittent time for 10 minutes, which perfectly meets the current situation of bus dispatching and realizes true plug-in operation.
