[Industry Transformation] Ruishu’s 3 MW flash‑charging technology puts an end to the chaos of battery‑swapping! Ultra‑fast charging for electric heavy trucks ushers in an era where charging speeds rival those of gasoline and diesel.

In 2025, sales of new‑energy heavy trucks surged 195.2% year over year, yet the charging‑infrastructure market has fallen into a paradoxical cycle: more than 40% of battery‑swap‑equipped heavy trucks are forced to retrofit charging ports—“abandoning swapping in favor of charging”—due to a shortage of swap stations and soaring costs. With each swap station requiring an investment of 5 million yuan and needing to serve at least 60 vehicles to break even, the high entry barrier deters small and medium‑sized fleets; meanwhile, inconsistent battery standards make it difficult to find compatible batteries, rendering the efficiency advantages of the battery‑swap model little more than empty rhetoric.

Just as the industry is mired in confusion, Ruisu Intelligent’s self-developed all-liquid-cooled 3 MW ultra-fast charging system Its sudden emergence has completely rewritten the industry landscape: 20 Charges to in minutes 80% Battery life and endurance are sufficient. 6 Hours of continuous operation can directly bring the energy replenishment of electric heavy-duty trucks up to the “fuel‑electricity parity” level, marking the official entry of construction‑site heavy trucks into the era of… The Megawatt Ultra-Charging Era ！
