Vehicle Control System is the key technology to new energy vehicles smooth operation. In 2014, Higer new energy vehicles sell 2,115 units of which the stability and energy efficiency has been widely proved and recognized by the market and customers. Higer new energy Vehicle Control System is unquestionably credited with the impressive performance of the sales of Higer new energy buses.
A set of new energy vehicle control system mainly comprised of the generator, motor controller, power battery and management system etc, among which the Vehicle Control Unit (referred to as VCU) is the core component, functionally equivalent of "brain", in charge of the vehicle to perform different tasks in different states during operation. By the end of Feb. 2015 2, Higer new energy VCU has been granted 18 state authorized patents, including 6 invention patents. At the same time, the enterprise standard on hybrid vehicle control unit based and electric vehicle control unit has been declared as the local standard of Jiangsu Province.
According to data collected form operation, fuel gas costs per 100 km of Higer plug-in hybrid electric bus is 154.7 yuan which is the lowest among six counterparts, which is the same situation when charging which is 147 yuan. At the same time, the during trial operation, some manufacturers are temporary adjustment of the electric control system to improve performance, some were stopped because of fault, only Higer buses delivered most stable performance. According to the investigation of trial operation on the drives, Hagrid plug-in bus is more stable, faster and convenient to operation, ranking the first among the six counterparts.
