What is BMS?
BMS is the abbreviation of BATTERY MANAGEMENT SYSTEM. It is a module specially used for lithium battery operation and management, and the object is lithium battery.
For general end users, they may not know that there is such a thing as BMS in the products they are using. For example, for electric vehicles, 100% of users know that there are batteries on electric vehicles because the batteries provide energy, but maybe only 1% of users know that there is a lithium battery protection board BMS.
The reason why BMS has such a low sense of existence is entirely because it cannot directly communicate with users, nor does it frequently interact with users. Even if some data is generated occasionally, these data are also transmitted through some dashboards. For users to observe, when they see the red light on the dashboard, they will say: "Well, the car seems to be broken, the quality is really bad."
Although BMS has a low sense of existence, its meaning is not inferior to the instrument, and it can even be said to be more important than the instrument, because it can detect whether the energy system of the car is broken. Only with the BMS system, the user It is possible to know whether this car is good or bad without taking risks.
If there is an embedded engineer in the industry who wants to buy an electric car and choose between an electric car without a display instrument and a BMS board, then he will definitely not dare to choose the latter, because if the electric car does not have an instrument, then the user The experience will be extremely poor, but if the electric car does not have a BMS... it is not so much an electric car as it is a bomb that may be activated at any time.
