AI Technical Summary
Technical Problem
Existing battery management systems fail to accurately discriminate between different types of ageing in electrochemical batteries, leading to suboptimal charging management and premature battery degradation.
Method used
A battery management system that measures internal resistance at multiple frequencies to differentiate between cycling and calendar ageing, adjusting charging currents based on these measurements to extend battery life.
Benefits of technology
The system effectively discriminates between different ageing types, optimizing charging currents to prolong battery life and prevent premature disqualification.
