HHV is the abbreviation for hydraulic hybrid vehicle, which means hybrid electric vehicle in Chinese
Hybrid electric vehicle refers to a vehicle whose vehicle drive system is composed of two or more single drive systems that can operate at the same time, and the driving power of the vehicle is provided separately or jointly by a single drive system according to the actual vehicle driving state.
The characteristics of hybrid electric vehicle such as energy saving and low emission have attracted great attention in the automotive industry and become a focus of automotive research and development. The hybrid power device not only plays the advantages of long continuous working time of the engine, good power performance, but also plays the advantages of no pollution and low noise of the motor, the two \"fight side by side\
hhv unit stands for inductive unit Henry. Henry is the International System of units derived unit of inductance, symbolized by H, this unit is named after the American physicist Joseph Henry, inductance is a property of the closed loop, is a physical quantity. When the current passes through the coil, a magnetic field induction is formed in the coil, and the induced magnetic field will generate an induced current to resist the current through the coil.
In electromagnetism, the amount of electricity passing through any cross section of the conductor in unit time is called current intensity, referred to as current, the current symbol is I, the unit is amperes (A), referred to as \"ampere\".
