Description

technical field [0001] The invention relates to the technical field of electric vehicle power systems, in particular to a multi-load high-voltage DC modular system for pure electric vehicles. Background technique [0002] The trend of vehicle electrification has brought new demands and challenges to high-voltage integrated components, especially in the field of combining commercial vehicles and electric vehicles. The market is small, highly differentiated, and the technology is immature. [0003] Existing product features: [0004] a. Modular power management system for low-voltage components, including a central controller to detect and control a series of power management modules that control low-voltage loads. These modules or the interfaces between modules do not have the performance of high-voltage systems, such as: high-voltage interlock, electromagnetic shielding, ground fault detection, load pre-charging, etc. Satisfying these properties requires completely differe...
