About the development direction of Chipu Electronics' smart balance car battery pack

We have always been concerned about the performance, appearance, accessories, and scalability of electric unicycles. But we don't know that there is a more important device in electric unicycles, that is, the battery.

The battery plays a vital role in the electric unicycle, but it is easily overlooked by most people. We have talked about how to maintain the battery of the electric unicycle before, you can go and have a look.

The battery not only ensures the driving speed of the unicycle, but also ensures its driving safety.

A lithium-ion battery pack, also called a pack, is a combination of lithium-ion cells and protection boards.

Protection boards are divided into hardware boards and smart boards. Hardware boards refer to circuit boards made with dedicated lithium-ion battery protection chips. Smart boards (also called software boards) refer to circuit boards that use general-purpose or dedicated microcontrollers to implement lithium battery management functions through software programming.

The electric unicycles we often see on the market are all equipped with protective plates. The protective plate is actually two modules separated from the main board, and there is no communication between them. The control main board of the unicycle cannot know the operating status and health of each battery, and can only simply obtain the voltage parameter. The lithium-ion battery pack composed of battery cells and smart boards is called a smart lithium-ion battery pack!

Comparison between smart version and hardware version:

shortcoming

Low application threshold

Smart Board

High price

High application threshold

With communication function

Accurately calculate remaining power

Can record cycle times and measure battery temperature

Overvoltage and undervoltage protection points can be flexibly set
