Description

technical field [0001] The invention relates to the technical field of automobile power management, in particular to an automobile power management controller. Background technique [0002] At present, automobiles are developing towards multi-functionality, comfort, luxury and reliability, and the power of generators configured is multiplied. Even for commercial transport trucks, the power of the generator has doubled on average in a few years to install more electronic and electrical components, such as eddy current retarders for auxiliary braking, air conditioners, refrigerators for domestic use, etc. . Electronic management components of automobiles, such as electronically controlled fuel injection systems, put forward higher quality requirements for power supplies. Since the battery equipped with the car is of a starting type structure, it mainly fulfills the requirements of starting the engine. In terms of matching the generator and the battery, it is required that th...

Problems solved by technology

[0003] However, the power generation capacity of existing automobile generators and battery capacity have not increased synchronously (limited by volume, weight, and cost), thus breaking the matching balance between generators and batteries, and the power generation capacity of generators reaches the charging current of batteries The battery is in the high current charging mode for a long time, instead of using the "constant current charging" method to switch to the "constant voltage charging" mode after the voltage rises to the rated voltage, resulting in the battery being in the overcurrent charging state for a long time. Early damage, frequent replacement of batteries increases environmental lead pollution
