EV charging & V2H debate
EV charging debate surfaced: a new platform’s claim of 10→80% in 29 minutes drew criticism versus BYD’s blade battery chemistry, and discussion emphasized V2H (vehicle‑to‑home) tech and high‑power onboard chargers (10–11 kW AC) as key differentiators for home backup use discussion discussion discussion. Bottom line: battery chemistry and bidirectional charging capability matter more than headline fast‑charge numbers for V2H value.
BYD unveiled its Super e‑Platform on March 17, 2025, touting flash‑charging architecture capable of up to 1,000 kW peak power and naming the Han L and Tang L as the first models to use it. byd.com Industry analysts and outlets warned those megawatt‑class numbers depend on new public chargers, connector and grid upgrades, and so real‑world deployments lag the lab and stage demos. bloomberg.com Home‑backup discussion in the thread centered on AC bidirectional setups that rely on a vehicle’s onboard charger; Enphase’s IQ Bidirectional lists up to 11.5 kW of AC bidirectional power for V2H/V2G use. enphase.com Wallbox’s Quasar 2 similarly markets V2H backup and energy‑management features for residential installs. wallbox.com Participants pointed to battery chemistry and bidirectional capability as the practical differentiators: BYD says its long‑form LFP “Blade” cells accept higher C‑rates to enable flash charging, while V2H backup runtimes are effectively capped by onboard/AC conversion and typically fall in the ~9–11.5 kW range (Tesla’s Powershare lists about 11.5 kW). evchargingstations.com
