The Bottleneck of Electric Heavy-Duty Truck Adoption – Charging Time
In 2025, China’s new energy heavy-duty truck market surged, with annual sales reaching 231,000 units – a 182% increase year-on-year, pushing the electrification penetration rate from 13.6% to 28.9%. However, conventional charging takes 1–2 hours, far from the refueling experience of diesel trucks. This gap has become the main obstacle to large-scale commercial vehicle electrification.
MW Charging Technology: Key Power Supply Requirements
MW-class ultra-fast charging is the answer. National policies and industry standards are accelerating – China’s MW charging standard is expected to be finalized in 2026. Leading solutions now offer 1.44 MW and 2400A steady-state output, cutting charging time for heavy trucks from 1–2 hours to around 15 minutes. For charging infrastructure operators, the AC/DC power supply for MW charging stations must meet several demanding requirements: high power density and efficient cooling (liquid cooling preferred), high reliability in harsh environments (dust, humidity, salt spray), and support for multiple inputs (grid + solar PV + storage) to optimize energy costs.
From Confined Sites to Long-Haul Logistics – The Market Shift
As MW charging technology matures, electric heavy trucks are moving from confined applications (mining, ports) to long-haul logistics. For fleet operators and charge point operators, early deployment of MW-class charging infrastructure is not just a policy response – it is a strategic move to capture the fast-growing commercial EV charging market.
