How can a 10BASE-T1S battery management system improve voltage monitoring?

Higher voltage monitoring could be achieved by stacking more modules while using 10Base-T1S Bus for isolated communication. This battery management solution offers state-of-charge determination using coulomb-counting and passive cell-balancing. It also comes with GUI support showing battery level and balancing.

Why is a battery management system important?

This translates into making the battery packs lower cost with higher energy densities. Every single watt-hour stored and retrieved from the cells is critical to extend the driving range. The main function of a battery management system (BMS) is to monitor cell voltages, pack voltages and pack current.

Can pac1954 monitor multiple stacks of battery modules?

This reference design demonstrates the monitoring of multiple stacks of battery modules. Each battery module is capable of monitoring up to 8 series 18650 Li-Ion batteries using the PAC1954. Higher voltage monitoring could be achieved by stacking more modules while using 10Base-T1S Bus for isolated communication.

What is a battery management unit (BMS)?

Figure 1 presents a typical BMS architecture containing a battery management unit (BMU), cell supervisor unit (CMU) and a battery junction box (BJB). A BMU typically has a microcontroller (MCU), which manages all of the functions within the battery pack.
