Figure 1 presents a typical battery management system architecture containing a battery management unit (BMU), a 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.

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.
Enter Battery Box: a local energy storage solution that helps manage the timing differences between intermittent energy generation and electricity usage.
There are no active electronics inside the junction box, and all measurements in the battery junction box are taken in the battery management unit. The battery terminal box is connected to the analog-to-digital converter (ADC) terminal by cable. Figure 1b shows the smart battery junction box.
The BMU usually contains a microcontroller (MCU) that manages all the functions in the battery pack. A traditional battery junction box is a relay box or switch box with a power contactor that connects the entire battery pack to a load inverter, motor, or battery charger. Figure 1a shows a traditional BMS.
