Description

Technical Field

[0001] This utility model relates to a power supply maintainer for maintaining vehicle system power supply when replacing vehicle batteries, belonging to the field of automobile repair and maintenance. Background Technology

[0002] In the field of automotive repair and maintenance, replacing a vehicle battery is a routine and necessary operation. However, during the process of removing the old battery and installing the new one, the vehicle's power system experiences a power outage. This power loss can lead to the loss of data stored in the vehicle's computer (ECU), audio system, clock, and other electronic devices, as well as the reset or reinitialization of personalized settings, causing inconvenience to users and, in severe cases, even affecting the normal operation of certain vehicle functions.

[0003] Currently, there are two main technical solutions to address the aforementioned issues. The first is to use a specialized car jump starter. These devices typically have built-in high-capacity batteries, are bulky and expensive, and are primarily designed for engine starting, making them too cumbersome and uneconomical for situations where only power to onboard electronic devices is needed. The second is to jump-start the vehicle using a battery from another vehicle. This operation is complex, poses safety hazards such as short circuits and reverse connections, and requires a high level of expertise from the operator. Neither of these solutions provides a safe, portable, and easy-to-operate solution specifically designed to provide continuous power to onboard electronic devices while the battery is being replaced.

[0004] Therefore, there is an urgent need in this field for a specialized device that is highly targeted, simple in structure, low in cost, and safe to operate. This device should be able to provide temporary, stable power to the vehicle's electrical system during battery replacement using readily available external power sources (such as common portable power banks), thereby ensuring that data from onboard electronic devices is not lost, greatly simplifying the operation process, and reducing operational risks.
