As global demand for energy storage solutions surges, it has become important to outline key strategies for optimising battery performance and extending operational lifespan. A critical focus is correct charging methods to achieve these objectives.

Warren Lazarus, Project Manager of Freedom Won, shared these valuable insights at the Africa Solar Industry Association’s fourth Energy Storage Solutions e-conference earlier this month.

“Utilising chargers specifically designed for the battery’s chemistry and voltage can prevent overcharging or deep discharging, which can both degrade battery health over time,” said Lazarus.

“Operating and storing batteries within recommended temperature ranges are essential to prevent performance degradation. Exposure to extreme heat or cold should be avoided to maintain battery efficiency.”

Minimising high discharge rates is a strategy to reduce stress on the battery and extend its lifespan, Lazarus added. Additionally, proper storage practices are important. He said keeping batteries clean, inspecting them regularly for physical damage or corrosion and ensuring proper ventilation for heat dissipation are vital.

Lazarus also highlighted the importance of implementing a robust battery management system (BMS) for lithium-ion batteries. A BMS offers various functionalities, including cell balancing, overcharge and over-discharge protection, temperature monitoring and control, state-of-charge and state-of-health monitoring, efficient charging algorithms, communication interfaces and fault detection and diagnostics.

Moreover, Lazarus advised adjusting device settings to reduce power consumption, upgrading firmware and software regularly and choosing the right battery for specific applications to ensure optimal performance.

“Regular recalibration by fully charging the battery, ideally weekly, helps maintain balanced cells and prolongs battery lifespan,” he said.
