Description

technical field [0001] The invention relates to the technical field of electronic energy detection, in particular to an electronic energy detection system and method. Background technique [0002] At present, in order to save energy and reduce emissions, the concept of new energy sources for vehicles has emerged, and the concepts of fuel cell vehicles, hybrid / weak hybrid vehicles, hydrogen energy vehicles and solar vehicles have emerged from this. Among them, the weak hybrid vehicle is to support low-speed coasting, stop and turn off the engine, use the coasting energy to store energy when the brakes are lightly stepped on, and assist the engine to do work together when the accelerator is heavy. Its core technology is the "forced start / stop" technology. [0003] The electronic energy detection system in the prior art cannot realize accurate measurement of battery voltage, current and temperature, and thus cannot accurately monitor various states of the battery, such as state...
