UCR researchers find commercial fast-charging damages EV batteries, propose new internal-resistance-based technique

Green Car Congress

Herein, industry based along with our proposed internal resistance (IR) based fast charging techniques were performed on commercial Panasonic NCR 18650B cylindrical batteries. They also charged a set using a new fast-charging algorithm based on the battery’s internal resistance, which interferes with the flow of electrons.

RMIT researchers demonstrate working rechargeable proton battery

Green Car Congress

Researchers at Australia’s RMIT University have demonstrated for the first time a working rechargeable “proton battery”. The rechargeable battery is environmentally friendly, and has the potential, with further development, to store more energy than currently-available lithium ion batteries. Earlier post.)

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

The findings are published in a paper in the International Journal of Hydrogen Energy. Comprehensive analysis of various factors, including rechargeable battery and electrolyzer capacities, enables the estimation of technology levels required for low-cost hydrogen production. This approximately converts to US$1.92 to US$3.00/kg
