【Abstract】High voltage components of new energy vehicles are the main components of new energy vehicles which are different from traditional vehicles. They play an important role in the operation of new energy vehicles. The communication between high voltage components is also based on CAN bus system. Taking Geely EV450 as an example，this paper analyzes the breakdown of CAN bus between new energy high-voltage components，and provides some reference for the maintenance of new energy vehicles.
