Control system and method for battery replacement

Abstract

The invention provides a control system and method for battery change. The system for cell change comprises a quick change device, multiple position sensors arranged on a battery, a subordinate inductive sensor, a subordinate controller, a main inductive sensor, a main controller, wherein the subordinate controller is used for acquiring a battery state signal, a latching-off signal of the battery and battery position signals detected by the multiple position sensors after a vehicle is electrified and transmitting the battery state signal, the latching-off signal and the battery position signals through the subordinate inductive sensor, and the main controller is arranged on the quick change device, connected with the main inductive sensor and used for receiving the battery state signal, the latching-off signal and the battery position signals sent by the subordinate controller and controlling the quick change device to move the battery according to the battery state signal, the latching-off signal and the battery position signals so as to change the battery. The control system can quickly and automatically achieve battery change and has the advantages of high safety and reliability.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a control system and method for battery replacement. Background technique [0002] At present, the main factors affecting the commercialization of electric vehicles are short mileage and long charging time. The solutions mainly include two ways: battery fast charging technology and battery quick replacement technology. [0003] Battery fast charging technology requires high battery temperature, and fast charging generates a lot of heat, which will shorten battery life. [0004] Battery quick change technology can effectively solve battery charging maintenance and battery life problems. The use of quick-change technology refers to the use of manual or automated quick-change equipment to replace the vehicle battery, which requires high dimensional accuracy between the quick-change battery and the quick-change bracket. However, using manual battery replacement equipment may easil...

AI Technical Summary

Problems solved by technology

However, using manual battery replacement equipment may easily lead to improper assembly of the battery or damage to the quick-change bracket during the assembly process, affecting the convenience of quick battery replacement. In addition, it is necessary to ensure that the battery is powered off at low voltage and the relay is disconnected during the battery replacement process. Battery replacement or automatic battery replacement equipment without monitoring the state of the battery can easily lead to damage to the quick-change contacts during the battery replacement process, causing high-voltage safety issues
