Can a programmable logic controller be used to control lithium-ion batteries?
Conclusion This paper proposed a programmable logic controller (PLC) based SOC implementation for accurate management of lithium-ion batteries. The designed PLC-based BMS enabled control and monitoring of the battery parameters (SOC, current, voltage and temperature).
How can a lithium battery pack charging system be operated autonomously?
Through the ground command, the lithium battery packs charging function can be started and terminated autonomously; the operating status (enable or disable) of each function module of the autonomous system can be controlled; the control threshold, parameters and processing coefficients of the autonomous system can be modified.
In electric vehicles, managing the battery pack alone is insufficient. The BMS must also communicate with the vehicle controller and charger. A smart battery management system is designed to enable self-protection of the battery pack while simultaneously integrating it with the charger and vehicle controller.
What is a programmable logic controller based battery management system (BMS)?
Their packs are usually equipped with accurate battery management systems (BMSs) to maintain the safe operation of the cells. To overcome the drawbacks of BMSs implemented with micro-controllers such as low reliability, low flexibility, and difficulties in troubleshooting, a programmable logic controller (PLC) based BMS is proposed in this paper.
What is a battery management system?
The battery management system is key to the safe operation of the battery system and is often equipped to track operating conditions and monitor the battery system for potential faults . Without real-time, effective fault diagnosis and prognosis methods, a small failure can lead to even serious damage to the battery system .
The autonomous system is divided into an autonomous charge and discharge management of lithium batteries module, an autonomous balanced management module, an self-overvoltage, over-temperature and over-current module, and an autonomous bus overvoltage protection module.
