Description

Technical Field

[0001] The utility model relates to the technical field of energy high voltage, in particular to a new energy high voltage for a 48V system of a motorhome. Background Art

[0002] The high-voltage system of new energy vehicles is the core component of electric vehicles, mainly involving key components such as battery packs, motors, and electronic controls. These components together constitute a complete electric drive system that provides power for the vehicle and ensures its safe and reliable operation. The operating voltage of the high-voltage system is generally above 200V, which is much higher than the 12V voltage of traditional vehicles. Its main purpose is to use power electronics technology to achieve energy conversion and distribution to drive the vehicle. The 48V system of an RV is usually a low-voltage system used for some auxiliary equipment and some electric drive systems. The new energy high-voltage system generally refers to the high-voltage battery system in electric vehicles or hybrid vehicles, such as 400V or higher systems, which are used to drive major power components such as electric motors.

[0003] During the design process of the RV rear area, many electrical equipment and energy storage devices, such as lead-acid batteries or lithium batteries, will be installed. In the past, energy storage devices could only use AC mains power to charge the battery pack through an on-board charger, and the charging speed was slow and inefficient. At present, new energy charging piles have been put into use in various places. Designing a new energy fast charging device for the RV 48V system can give full play to existing public resources and improve the convenience of RV travel.

[0004] There are multiple heat sinks inside the new energy high voltage. If the heat sink is blocked by dust, dirt or other substances, it will hinder the air flow and cause the heat to not be effectively dissipated, which will increase the temperature of the hardware and affect the performance and stability of the equipment.
