Scope

This part of IEC 62864 applies to series hybrid systems (electrically connected) with onboard energy storage (hereinafter referred as hybrid system). A hybrid system has two (or more) power sources including energy storage system (ESS) on board to achieve the following features by combining converter and motors and performing energy management control: ? improving energy and fuel efficiency@ improving acceleration characteristics@ increasing running distance and uninterrupted running in the event of the loss of the primary power source (PPS)@ by using an ESS in addition to the primary power source under conditions where the power and capacity of the power source including regenerative power are limited@ thus alleviating those limitations; ? reducing fuel consumption@ reducing emissions (e.g. CO2@ NOx@ PM@ etc.); ? reducing environmental impact (e.g. visible obstruction@ noise@ etc.). By extension@ systems that have only onboard ESS@ without other PPSs@ is also considered in this standard. This standard intends to specify the following basic requirements@ characteristics@ functions and test methods for hybrid systems: ? energy management to control the power flow among primary power source@ energy storage system and power converters; ? energy consumption@ energy efficiency and regenerated energy; ? vehicle characteristics achieved by energy storage system; ? test methods of combined test; and ? test methods of completed vehicles based on factory (stationary) and field (running) tests. NOTE Converter in this standard means combined equipment consisting of one or more converters (e.g. rectifier@ inverter@ chopper@ etc.). The interfaces between the following power sources are covered: ? external electric power supply system; ? onboard ESSs (including pure onboard energy storage); ? fuel cell@ diesel electric generator; and ? other power sources. As for the combination of inverters and motors@ this standard applies to asynchronous motors or synchronous motors that are powered via voltage-source inverters. Power source systems and combination of inverters and motors are not limited to the listed above@ but this standard can also be applied to future systems. This part of IEC 62864 covers electrically connected systems (series hybrid)@ and not systems that mechanically transmit the driving force (parallel hybrid).
