Huawei raises liquid-cooled charging to 800 A and cuts grid connection requirement to 50 kW with new DC ESS solution

Huawei Digital Power unveiled an 800-ampere liquid-cooled DC charging dispenser and a new DC ESS+Charger Solution at Power2Drive Europe 2026, held at Messe München from 23 to 25 June 2026, targeting charging operators who cannot secure adequate grid capacity upgrades^[1].

What changed from last year

The headline hardware step is a jump in dispenser current. Liquid-cooled DC dispensers now reach 800 A, and boost DC dispensers reach 600 A^[1] - up from 500 A per connector on the equivalent 2025 product. The dispenser supports a 150-1,000 V voltage range and keeps noise below 55 dB through full liquid cooling^[1].

The system delivers up to 720 kW of total power and can add 200 km of range in five minutes^[1]. The solution has received prime-level safety certification from TÜV^[1].

A megawatt charger has also launched in China and is undergoing field testing ahead of introduction to Europe^[1].

The grid-constraint argument

The DC ESS+Charger architecture is Huawei's answer to a specific commercial problem: charging operators in Europe who want to deploy ultra-fast charging but face slow or expensive grid connection upgrades. The DC ESS+Charger Solution builds on Huawei's earlier AC ESS+Charger offering and is explicitly positioned for Europe's ageing grid infrastructure^[1].

The claimed advantages of the DC-coupled architecture over AC-coupled alternatives are:

• Grid connection requirement of just 50 kW, eliminating the need for capacity-expansion applications^[1]
• A DC bus connected directly to the DC BESS resolves energy export issues entirely^[1]
• One fewer power conversion stage lifts ESS round-trip efficiency to 92.1%^[1]
• No power distribution construction required, cutting site build time from months to weeks^[1]

Two deployment scenarios

Huawei has structured the solution around two site types:

• New construction (residential communities, gas stations): operates within sub-240 kVA grid capacity, pairing 240-720 kW power units with a 1C DC ESS. Huawei claims this cuts payback by 1.5 years versus the industry average^[1].
• Reconstruction: reusing existing 240 kVA capacity and cabling with a DC ESS can expand a site from four to 12 parking spots, each capable of delivering up to 600 kW^[1].

A power-sharing matrix and intelligent power scheduling allow flexible configuration across dispensers, which Huawei says improves station turnover for charging point operators^[1].

Ecosystem positioning

Huawei is presenting the solution as more than hardware. The FusionCharge offering integrates PV, ESS, and charging into a single architecture, with the DC bus enabling on-grid or off-grid operation depending on site conditions^[1]. Huawei Digital Power has deployed charging networks across more than 60 countries and regions.

The modular design is intended to allow operators to upgrade from fast to ultra-fast charging without secondary capital investment - power units, dispensers, and ESS can all be swapped independently^[1].

What to watch: whether European charging point operators adopt the DC-coupled ESS architecture at scale, or whether grid upgrade timelines improve enough to reduce the commercial case for behind-the-meter storage at charging sites. Huawei's megawatt charger timeline for Europe will also be a marker of how quickly the company expects high-voltage EV adoption to accelerate on the continent.
