What is a Battery Control Unit (BCU)?
Since battery cells require a proper working and storage temperature, voltage range, and current range for lifecycle and safety, it is important to monitor and protect the battery cell at the rack level. battery control unit (BCU) is a controller designed to be installed in the rack to manage racks or single pack energy.
What does a battery MCU do?
The MCU responsible for actually charging the battery must be able to quickly adjust and adapt in real time to the battery’s changing properties, like oxidation on the terminals or cell voltages. During charging, the MCU must be able to respond quickly to overvoltage conditions; otherwise, the battery may overheat and catch on fire.
Which PCB is placed inside battery module connected with CMU?
Flexible PCB placed inside battery module connected with CMU. Fig. 8. Battery System Architecture. The metal tabs are used to weld on the cell connecting bus bars for sensing the cell voltages. These will avoid all the wires inside the battery module making it more rigid.
How does a CMU control a battery?
These CMU will communicate with the Master Controller Unit (MCU) to control the battery operations in its safe operating area over isolated Serial Peripheral Interface (isoSPI) communications reducing the bulky low-voltage wiring harnesses and further reducing the weight and complexity. 1. Introduction
Are MCUs required in a battery management system (BMS)?
Depending on the level of modularization within the battery, there could even be communications required within the BMS itself. The most important criteria for MCUs within the BMS is functional safety capability. Security is also becoming increasingly important, as networking levels continue to increase.
