What happened

UNSW researchers developed a prototype that assesses lithium-ion battery health by applying short electrical pulses to individual cells and evaluating their responses through statistical models.^S1 The laboratory process estimates battery condition in under three minutes per cell and achieved more than 90% accuracy, according to the researchers.^S1 The team said the method is 95.5% faster and more than 80% cheaper than existing testing approaches, while targeting a price below AUD 25.^S1

Current testing of used batteries generally requires a full charge-and-discharge cycle lasting about 10 hours, costing about AUD 120 per EV battery pack.^S1 The researchers said prolonged high-stress cycling can cause overheating and fire when damaged batteries are tested.^S1 The prototype supports lithium iron phosphate, nickel cobalt aluminum, and nickel manganese cobalt chemistries and is designed to interface with management systems used by recyclers and energy storage operators.^S1

UNSW and Malaysia-based DY New Energy are working on an AUD 1.3 million project intended to evaluate more than 500 batteries under real-world conditions.^S1 Before pilots at recycling facilities and second-life storage systems, the partners plan to develop a machine-learning decision engine for classifying retired batteries for reuse or recycling.^S1 An iBMS module will subsequently deliver those recommendations to battery systems for real-time monitoring and decision support.^S1
