Many sites have limited availab le power. A typical 4-charger installation can reserve up to 20% of a dist ribution substation's capacity (often 5–15 MW total). Once installed\, v ariable charging loads\, driven by vehicle curves and utilization patterns \, ultimately underutilize the reserved grid capacity. Expensive utility u pgrades are frequently required to accommodate these loads. Electric Era's closed-loop\, real-time control system uses battery storage to shave peak s\, enabling charging rates to actually and easily exceed the site's physi cal grid connection capacity without impacting utility service or tripping breakers. The presentation includes a case study demonstrating advanced v oltage regulation through volt-var optimization\, where the battery system stabilizes a weak local grid by compensating for voltage changes during c harging and load rejection events\, enhancing overall grid reliability and accelerating deployment of high-power EV infrastructure.\nBio: Hasitha "S ith" Dharmasiri is the Vice President of Software at Electric Era Technolo gies\, a Seattle-based innovator in battery-backed DC fast charging infras tructure.
