Introduction to L9963 BMS controller

Hello, readers welcome to new post. We will discuss Introduction to L9963 BMS controller. This module is designed by STMicroelectronics that is bettery management technique useful for increasing the reliable operation and operating duration safety of electric vehicles.

It was created to fulfill the major demands of electric vehicles like volts accuracy to operate long time internal and high battery life. In this post, we will discuss its working features and some other points. So let’s get started Introduction to L9963 BMS controller

Table of Contents

The L9963 is a lithium-ion battery used in electric vehicles for energy storage and is known as a monitoring and protection board.

It has about fourteen stacked battery cels that fulfill the volts demands of forty wight volts and a larger volts system.
Every cell volt can be found with a high level of accuracy with the current for onboard charging measuring.
It has the ability to monitor the seven NTC and uses the SPi protocol for data transfer.
Numeroru modules can be arranged in a chang-like arrangement and make communication to single processors through the use of transformer-isolated interfacing that results in high speed less EMI and larger distances data transmission.
It has features of passive balancing in case of normal and low power mode.
Its balancing can be eliminated on the base of inner timer interrupt.
It has 9 general purpose input and output pinouts for the regulation of outer devices.
