A cybersecurity expert successfully hacked a BYD Shark hybrid ute, gaining remote control of non-critical functions like lights and wipers with minimal security protections. The demonstration highlights concerns about Chinese EV manufacturers' surveillance and control capabilities, particularly given China's national security laws that could compel data sharing with authorities.
Chinese battery maker Sunwoda unveiled a new 15C LFP battery technology that charges from 10-97% state of charge in 9 minutes at room temperature, adding 100 km of range per minute. The system achieves these ultra-fast charging speeds through advanced thermal management and maintains a 10-year or 300,000 km warranty without limiting ultrafast charging cycles. Sunwoda also introduced a broader energy ecosystem integrating solar power, battery storage, and charging infrastructure for partnerships with energy companies.
EV charging involves unavoidable losses as electricity is transmitted and converted from grid AC to battery DC. Testing shows AC Level 1/2 chargers typically lose 14–20 percent of electricity to heat, conversion, and thermal management, while DC fast chargers lose approximately 10 percent. Using dedicated wall-mounted chargers significantly reduces losses compared to household outlets.
Porsche has launched wireless inductive charging for its Cayenne Electric SUV, allowing drivers to charge by parking over a ground pad rather than connecting cables. The system offers up to 11 kW charging power with 90% efficiency and includes safety features like motion sensors and foreign object detection. The technology is available for order in Germany and other European markets.
Cornell University researchers developed Direct Electrode-to-Electrode Regeneration (DEER), a chemical recycling technique that restores end-of-life lithium-ion batteries to 95% capacity by removing accumulated solid electrolyte interphase layers, offering a more efficient alternative to traditional battery recycling methods that destroy battery components.
