Access status update (March 28, 2026): BYD confirmed its Flash Charger is open to all EVs meeting national standards [C — Dongchedi, March 9, 2026]. The access barrier is resolved. This gap now concerns charging speed, not access.
What remains DATA NOT AVAILABLE: the power a non-BYD vehicle actually receives at a BYD Flash Charger. Before current flows, the charger and the vehicle battery management system negotiate a firmware handshake. BYD co-designed both sides of that handshake for its own vehicles. For non-BYD vehicles, the power ceiling produced by that negotiation has never been published by BYD or any independent testing organization.
Scope: applies to all non-BYD EVs. Four physical mechanisms may reduce delivered power: firmware negotiation ceiling, vehicle thermal management conservatism, state-of-charge behavior above 80%, and any operator software tier policy.
Closest available analogy: Tesla Supercharger V3 opened to non-Tesla vehicles in Europe in 2024. Independent measurements showed non-Tesla vehicles receiving 160–200 kW against a 250 kW peak — a 20 to 40 percent power discount [V — multiple independent EU measurements, 2024].
