Problems solved by technology
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. This invention proposes a management system that can identify whether the charger and the battery match to manage the charging of electric bicycles.

Embodiment 1
[0024] Such as figure 1 As shown, a battery management system suitable for electric bicycles, including power supply module, charging detection module, discharge detection module, wake-up and low power consumption working module, voltage acquisition module, current acquisition module, processor, charger and battery information The display module, power supply module, charging detection module, discharge detection module, wake-up and low power consumption working module, voltage acquisition module, current acquisition module, charger and battery information display module are all connected to the processor.
[0025] The charging detection module is connected to the positive pole of the battery and the positive pole of the charger, and is used to detect whether the charger matches the battery, and sends the detection result information to the processor; the discharge detection module is connected to the positive pole of the battery, and is used to detect whether the battery enter...
Embodiment 2
[0034] This embodiment provides a management method for an electric vehicle battery management system, including the following steps,
[0035] When the electric vehicle battery is connected to the charger, the charging module starts to work and wakes up the system first, and then detects whether the charger matches the battery through communication with the charger. If it matches, the charger is allowed to charge the battery; the working steps of the charging detection module are as follows , When the charger is charged, point D can detect a low level, indicating that the charger is involved. When the system detects that the charger is a matching charger, the charger is allowed to charge the battery by pulling up the voltage of point C.
[0036] When the electric vehicle key is turned on, the discharge detection module starts to work and wakes up the system, and the detection system enters the discharge mode; the working steps of the discharge detection module are as follows. ...

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...
