New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. Specifically, after 345 charge/discharge cycles at high current, this acidic reaction mechanism retained 82.8%

Improve EV charging ROI and customer experience by choosing the right fast chargers

Charged EVs

Some charging operators assume they need the highest-power DC chargers available, but it makes more sense to choose the right power levels for the use case of each specific charging site. Charged : When we started covering Tritium in 2011, the company was making a controller people used to build custom EVs.
