Battery management system and method suitable for electric bicycle

Abstract

The invention relates to the technical field of battery charging and discharging management, in particular to a battery management system management method suitable for an electric bicycle. A batterymanagement system suitable for an electric bicycle comprises a power supply module, a charging module, a discharging detection module, an awakening and low-power-consumption working module, a voltageacquisition module, a current acquisition module, a charger communication module, an instrument communication module and a processor connected with all the modules. The charging detection module is connected with a battery and a charger; the discharging detection module is connected with the positive pole of the battery; the awakening and low-power-consumption working module is connected with thebattery, the charger and the discharging detection module; the voltage acquisition module acquires the voltage of a battery in a battery pack; the current acquisition module collects charging and discharging current of the battery; the charger communication module communicates with the charger; and the instrument communication module communicates with an instrument to display the related information of the battery. According to the invention, the special charger matched with the battery can be identified, and economic loss caused by misuse of the charger by a user is effectively avoided.

Description

technical field

[0001] The invention relates to the technical field of battery charge and discharge management, in particular to a battery management system and management method suitable for electric bicycles. Background technique

[0002] There are a large number of electric bicycles in our country. Whether it is a city or a rural area, almost every household has electric bicycles. Electric bicycles have high travel efficiency, and there is no need to worry about traffic congestion. The electric bicycle needs to charge the battery before use. When the original charger of the electric bicycle is damaged or lost, most users now basically buy a charger and charge it, and use a charger that does not match the battery for a long time. When charging the battery, it is easy to damage the battery, and it will cause safety hazards and economic losses. Existing electric bicycles are generally not equipped with a battery management system. The present invention proposes a management...
