A study of almost 5,000 EVs revealed modern high-voltage batteries can go for years and years with minimal degradation. The degradation rate has decreased by almost a quarter compared to 2019. “Batteries in the latest EV models will comfortably outlast the usable life of the vehicle and will likely not need to be replaced.” That’s … Continue reading “EV Batteries Can Outlast A Vehicle’s Lifetime With Minimal Degradation, Study Finds”

Engineers at Southwest Research Institute (SwRI) have identified cybersecurity vulnerabilities in DC fast charging EVSE. In a laboratory, the SwRI team exploited vulnerabilities in the power line communication (PLC) layer that transmits smart-grid data between vehicles and charging equipment, gaining access to network keys and digital addresses on both the charger and the vehicle. The … Continue reading “SwRI finds cybersecurity risks in EV fast charging equipment”

Lithium iron phosphate (LFP) batteries are cheaper to produce and more stable than traditional nickel-based chemistries. A new study from a Tesla-funded lab found that LFP batteries degrade faster when fully charged. Repeated charging at a higher state of charge increases negative reactions within a pack. Electric vehicles powered by lithium iron phosphate (LFP) batteries … Continue reading “LFP Battery Health Degrades At Full Charge, Study Finds”
