With domestic trend of energy conservation and remission reduction, development of new-energy bus is on the road of the development pattern mentioned at the first. Since technology of plug-in hybrid electric bus gets developed and mature, plug-in hybrid electric bus begins to replace hybrid bus by its excellent performance.
Higer Plug-in ISG coaxial direct-drive multiple-serial system consists of motor and engine to directly drive driving wheels of the vehicle without any transmission for power delivery and torque change. Thus, loss of power caused by transmission would be decreased and drive efficiency would be enhanced. While started, the vehicle would be supplied with power by motor. The maximum speed would reach 30km/h, which could completely show advantage of motor in high torque and avoid the low efficiency of engine in low revolving speed. Only out of limited range of speed, engine can drive vehicles and remain the most efficient revolving speed range. Plug-in structure makes the vehicle run over 30km while fully charged. Therefore, this bus can have the best energy conservation even in continuing low-speed condition of urban traffic.
What’s more, Higer ISG direct-drive multiple-serial system can supply auxiliary power by dual-motor united drive when vehicle is in full-load and sudden speed up. Then, hybrid electric bus can achieve effect of high-power engine by its small-power engine, without any large-displacement engine. Meanwhile, power and energy efficiency can be ensured, which is totally different from the original BSG multiple-serial system bus.
Major systems of Higer new-energy bus are approved by reliable test of 1 million kilometers. By now there are over 3,000 buses in the market and approved by 3-year use. Warranty of Higer new-energy bus lasts for 3 years or 150,000 kilometers. And warranties of Higer capacitance and battery are respectively 8 years and 4 years.
