AI Technical Summary

Technical Problem

In automotive aftermarket service scenarios, battery testing results are affected by the vehicle's static current and the surface charge effect at the end of charging, leading to inaccurate test results and affecting the reliability and accuracy of the tests.

Method used

By acquiring the vehicle's static current, disconnecting the battery from the load and allowing it to stand for a period of time, an initial test is performed. If charging is required, the battery is charged to full capacity. After standing for a period of time, another test is performed to eliminate interference from static current and surface charge effects, generating prompt information to guide maintenance personnel.

Benefits of technology

It improves the accuracy and reliability of battery testing results, reduces false positives and invalid charging, and enhances the user experience.

Abstract

The application discloses a passenger car storage battery post-sale supplement detection method, device, equipment and product, and relates to the technical field of vehicles. The method comprises the following steps: obtaining the whole vehicle static current of the passenger car; when the whole vehicle static current of the passenger car meets the requirements, after the storage battery of the passenger car is disconnected from the load and is at rest for a first preset time length, the state of the storage battery is detected for the first time by a storage battery detector, and a first detection result is obtained; when the first detection result indicates that the storage battery needs to be charged before being detected, the storage battery is charged by a charger until the storage battery is fully charged; after the storage battery is fully charged and is at rest for a second preset time length, the state of the storage battery is detected for the second time by the storage battery detector, and a second detection result is obtained; and when the second detection result indicates that the storage battery is good, a first prompt information is generated, and the first prompt information is used for prompting a post-sale maintenance personnel that the storage battery can be continuously used. The application can improve the accuracy and reliability of the detection result.
