We have always been concerned about the performance, appearance accessories, and scalability of electric unicycles. But I don’t know that the electric wheel has a more important device, that is, the battery.
The battery plays a vital role in the electric unicycle, but it is easy to be ignored by most people. We have talked about how to maintain the electric unicycle battery and so on. You can go and take a look.
The battery not only guarantees the driving speed of the wheelbarrow, but also guarantees driving safety.
Lithium-ion battery packs, also known as packs, are composed of lithium-ion batteries and protective plates.
The protection board is divided into hardware board and smart board. The hardware board refers to a circuit board made with a dedicated lithium-ion battery protection chip. Smart board (also called software board) refers to a circuit board that uses general-purpose or special-purpose single-chip microcomputers to realize lithium battery management functions through software programming.
The electric unicycles that we often see on the market are all plate guards. The protective plate is actually two modules separated from the main board, and there is no communication between them. The control board of the wheelbarrow cannot know the operating status and health status of each battery, and can only simply obtain the voltage parameter. The lithium-ion battery pack composed of batteries and smart boards is called a smart lithium-ion battery pack!
Big comparison between smart version and hardware version:
Data communication is not possible
No power calculation function
No software logging function
Overvoltage and undervoltage protection points cannot be adjusted
The overcurrent protection value is only one level
Low application threshold
High application threshold
With communication function
Accurately calculate the remaining power
It can record the number of cycles and measure the battery temperature
Overvoltage and undervoltage protection points can be flexibly set
Multi-level overcurrent protection
