Using EV charging as a "shock absorber" for the grid
You've heard me complain that we don't spend enough effort on "smart charging" – the concept of varying the rate of EV charging to accommodate different conditions. So you won't be surprised that I'm very pleased that AeroVironment has integrated grid-friendly technology into its charging stations. Licensed from Pacific Northwest National Laboratory, the technology monitors grid frequency and varies its charging rate accordingly. It can even stop charging entirely if it detects the kind of rapid frequency drop that indicates a likely fault...
