Researchers at Victoria University of Wellington and Chalmers University of Technology developed a TD3-Powered Charger using a deep reinforcement learning algorithm that adapts safe voltage levels during charging based on a battery's current degradation state.The system adapts charging behavior based on a battery’s degradation state, dynamically adjusting safe voltage levels during charging rather than relying on fixed routines.
In simulation tests using a real-world battery model, the AI-driven method extended battery cycle life by roughly 23%, reaching around 703 equivalent full cycles compared with 572 under conventional charging approaches, while still achieving an 80% charge in about 24 minutes. The researchers also noted that the system was trained using consumer-grade computing hardware instead of specialized high-performance infrastructure.
For EV drivers and fleet operators, adaptive charging systems could reduce battery wear while preserving fast-charging convenience, lowering replacement costs and improving long-term vehicle efficiency. The research also reflects a broader trend toward AI-managed energy systems that optimize performance in real time based on equipment condition and usage patterns.
