Series hybrid electric vehicles can combine low-carbon
engines such as gas engine and methanol engine with electric drive to
effectively reduce carbon emissions, which is an important development
direction for road trucks. Series hybrid mainly consists of generation system,
battery and drive system, which jointly power supply with the battery to meet
the power consumption requirements during vehicle operation. Seeking the
optimal power distribution between battery and generation system is crucial for
hybrid energy conservation. For a gas-electric hybrid
truck, a new hybrid power control method was proposed by fully utilizing the
efficiency difference between battery and generation system and combining the
load characteristics of road, which could effectively improve the efficiency of
power supply system. Compared with rule-based control
method, the economy improved by 10.6%.
