Health-conscious Fast Charging Strategies and Battery Management Systems for Electrified Autonomous Transportation
Enhancing the calendar life and safety of Lithium-ion battery packs has been the topic of much interest when it comes to transportation electrification. In this framework, the role of on-board active cell voltage balancing of Li-ion batteries will be highlighted in this talk. This is a very important topic in the context of battery energy storage cost and life/state-of-charge, SOC/state-of-health, SOH monitoring. This talk will also introduce a first-of-its-kind closed-loop cell charge (voltage) balancing and extreme fast charging technique. The technique uses instantaneous cell voltage and/or temperature rise (ΔT) as a control parameter.
