Scope
QC/T 837-2010 is the English-translated version of 混合动力电动汽车类型.
QC/T 837-2010 is the Chinese automotive industry standard that sorts hybrid electric vehicles into types and defines each one.
Vehicles are classified by powertrain structure, such as the series hybrid, by hybrid degree, where for example a micro hybrid relies on the engine as main power source and its motor peak power is under 10% of total power, and by external charging capability, separating off-vehicle chargeable designs.
A further division covers driving mode selection, with and without a manual switch between engine, pure electric and hybrid modes, and other groupings may follow the rechargeable energy storage system, fuel type, structure or use.
It relies on the vehicle definitions of GB/T 19596 and applies to all hybrid electric vehicles. Issued on 22 November 2010, it has applied since 1 March 2011.

1 In this standard, it refers to the peak power of the driving motor.
4.2 By hybrid degree
4.2.2.1 Micro hybrid electric vehicle
The hybrid electric vehicle using the engine as the main power source AND the motor as an auxiliary power, which has the braking energy recovery function.
The ratio of motor peak power to total power is less than 10%.
4.3 By external charging capacity
4.3.1 Off-vehicle chargeable hybrid electric vehicle
A hybrid electric vehicle designed to take electrical energy from off-board devices under normal use.
4.4 By choice of driving mode
4.4.1 Hybrid electric vehicle with selection switch
