Abstract

The invention relates to a method for updating BMS embedded software of a shared battery. The method comprises the steps that 1, charging the battery; 2, detecting the version of the embedded softwareof the BMS; and 3, judging whether the version is the latest version or not, if so, continuing to charge, and otherwise, updating the BMS embedded software during battery charging. The BMS embedded software of a lithium battery in a two-wheeled vehicle or a three-wheeled vehicle can be updated on the premise of not increasing any hardware equipment, the scheme is simple to implement, and the hardware cost is not increased. Besides, the higher the utilization rate of the battery is, the more the charging and battery replacing times are, correspondingly, the shorter the time required for updating the BMS hidden danger software version is, and the more timely the updating is, so that the use safety of the battery is improved. Furthermore, for the user, BMS software updating is invisible, andthe user has no difference from normal battery charging and replacing in operation.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a battery-sharing BMS embedded software updating method. Background technique [0002] At present, the stability and safety of lithium batteries in two- and three-wheel electric vehicles mainly depend on the battery management system (BMS: BATTERY MANAGEMENT SYSTEM), and the measurement and control logic of BMS cannot be separated from software. Due to the limitations of human thinking, software sometimes has errors that can only be discovered after long-term use or thinking. If the hidden hidden software embedded in the BMS is not updated in time, it will affect the safety performance of lithium batteries. However, due to aging, failure, environment and other reasons, many lithium batteries are offline for a long time and cannot be connected to the background server. Therefore, the BMS software version cannot be updated in time, making them in a hidden working state for a lo...
