Hydro-Québec and Sony forming JV to develop large-scale Li-ion energy storage system for power grids

Green Car Congress

Hydro-Québec and Sony Corporation will establish a joint venture to research and develop a large-scale energy storage system for power grids. Furthermore, the energy storage system for such power supplies must be highly safe and reliable due to the need for an efficient and stable source of high capacity power.

Siemens Exploring Charging at Up to 300 kW for EVs; 6 Minutes for an EV Recharge

Green Car Congress

The long-term goal is to achieve up to 300 kW of charging capacity—enabling a quick recharge in roughly 6 minutes. The development engineers are also investigating how the constant switching on and off of the batteries affects the power grid; the harmonics this generates could knock the grid out of sync.

Will Supercapacitors Come to AI's Rescue?

Cars That Think

These coordinated spikes can strain the power grid, and the issue is promising to get worse rather than better in the near future. AI workloads sometimes use power in short bursts, causing the power grid to see a wildly oscillating load (blue). This becomes particularly important when transitioning to renewables.
