Electric bicycle battery management system and method based on block chain

Abstract

The invention belongs to the technical field of battery management, and particularly relates to an electric bicycle battery management system and method based on a block chain. The system comprises anelectric quantity detection device, a vehicle-mounted data memory, a vehicle-mounted 5G communication module and a battery management system server, the electric quantity detection device is arrangedin a lithium battery and is connected with the lithium battery, the input end of the vehicle-mounted data memory is connected with the electric quantity detection device, data transmission is carriedout between the output end of the vehicle-mounted data memory and the vehicle-mounted 5G communication module, and data transmission is carried out between the vehicle-mounted 5G communication moduleand the battery management system server. The electric bicycle battery management system and method have the beneficial effects that the electric quantity of an electric bicycle can be collected, displayed and recorded, data are recorded into the block chain for subsequent tracing and cannot be tampered, real-time electric quantity data are fed back to a bicycle owner and a battery management platform in a non-delay mode, and the optimal charging time and place can be recommended.

Description

technical field [0001] The invention belongs to the technical field of battery management, and in particular relates to a block chain-based electric bicycle battery management system and management method. Background technique [0002] As a convenient means of transportation, electric bicycles have become the most widely used means of transportation due to their low price, high speed and low noise. The battery is the power source of electric bicycles. Due to its high energy density and no pollution to the environment, lithium batteries are used more and more widely. However, the chemical nature of the lithium battery is active. To use the lithium battery safely, it is necessary to monitor and control the working status of the lithium battery to prevent the lithium battery from overcharging, overdischarging, overheating, short circuit, etc., otherwise the service life of the lithium battery will be severely shortened. Even lead to safety accidents. Currently on the market f...

Problems solved by technology

[0004] Both of these two patents realize real-time monitoring of battery power usage status, but using ordinary data memory storage, on the one hand, people can read and write these power data, which is not traceable and is not tied to the identity of the car owner. Once the battery is stolen, it is not conducive to solving the case, or when conducting second-hand transactions, the merchant conceals the real usage of the battery from the customer, and cannot guarantee the safety and reliability of the transaction; on the other hand, although the power is displayed, there is a delay in the display, and the power record is inaccurate. The user cannot accurately judge the charging time, and it is easy to cause overcharging or insufficient charging, which will have a negative impact on the battery.
