Description

Technical Field

[0001] This utility model relates to the field of parking power supply technology, specifically a parking power supply device with voltage and current control functions. Background Technology

[0002] With the increasing demand from scenarios such as self-driving tours and outdoor operations, the market demand for parking power supplies, as emergency power supply devices after vehicles are turned off, continues to grow. Currently, the industry's parking power supply products generally focus on "increasing energy storage capacity" as the main research and development direction, meeting users' needs for longer driving range by increasing the battery pack capacity. Their structural design and manufacturing process are mostly based on the standards of traditional stationary energy storage equipment. However, in actual applications, the voltage and current requirements of parking power supplies are even higher than those of power battery scenarios. This situation directly leads to problems such as the devices being unreliable and having a high failure rate. Even worse, insufficient compatibility can cause safety hazards such as overheating and fire, making it difficult to meet the safety and reliability requirements in actual applications.
