960kW 1440kW Power Pool Charging Stack 12 Guns 600kW Single Gun Output for Highway Super Charging Plaza

One power pool, twelve bays. The 960kW / 1440kW stack pools all 40kW SiC modules behind a shared DC bus and distributes them across up to 12 liquid cooled terminals, so a busy plaza keeps every bay live without installing a dedicated charger per parking space. A typical layout shares 960kW across 11 parking bays, lifting site utilisation while holding the grid connection within its limit.

• 960kW and 1440kW power pools: high capacity cabinets sized for plazas and depots with continuous traffic.
• Up to 12 charging guns: one cabinet serves a whole row of bays, cutting civil works and cable runs.
• 600kW single gun output: ultra fast charging adds roughly 200km of range in about 3 minutes on capable vehicles.
• 40kW SiC modules: 97 percent or higher peak efficiency with lower heat loss at partial load.
• 40kW granularity: capacity is dispatched in 40kW blocks to match each vehicle's acceptance curve.
• Power factor 0.99 or higher: keeps harmonic distortion low and avoids transformer upgrades.
• 600A liquid cooled terminals: sustained high current sessions without cable overheating or derating.
• 2015 and Chaoji standards: serves today's GB/T fleet and future ultra fast models from the same terminal.
• Power pool sharing design: 11 bays can share 960kW, so installed capacity tracks real demand instead of bay count.
• IP54 and -30°C to 85°C: outdoor operation with automatic derating in extreme heat.
• Full connectivity: RFID, GPRS, RS485, CA and Ethernet with OCPP 1.6 for CPO platforms.
• 5M / 10M cable, 2000m altitude, 5%-95% humidity: suited to highland and coastal sites.

• Capacity follows vehicles: an idle bay releases its share to a bus or truck that can accept more power.
• Typical plaza layout: 960kW shared across 11 parking bays, with a 1440kW configuration for larger sites.
• 40kW blocks: each session receives multiples of 40kW, matching module output exactly and avoiding conversion waste.
• Queue smoothing: short high power sessions run alongside longer low power sessions without starving either.
• Transformer protection: site load can be capped below the connection rating while all bays remain operational.

• Short circuit and overcurrent protection per output branch.
• Earth leakage monitoring with DC residual current detection.
• Emergency stop at cabinet and every terminal.
• PC flame retardant shell and segregated busbar compartment.
• Liquid cooling circuit monitoring with leak and pressure alarms.
• Overtemperature derating, surge protection and door interlocks.

• Highway super charging plazas and rest areas
• Fleet hubs, logistics parks and distribution centres
• Bus depots, taxi ranks and ride-hailing stations
• Large commercial parks and public parking facilities

Gun count, bay layout, terminal type, connector mix, payment integration, cabinet branding and interface language can be tailored to each project. We provide site sizing support, single line diagrams for approval, factory acceptance testing and commissioning guidance for CPO, utility and fleet customers.

Mckee has built EV charging systems since 2011, from AC wall boxes and portable plugs to 60-360kW DC fast chargers and flexible shared charging stacks up to 1440kW. Products are CE and TUV certified, and OEM/ODM projects are supported with customized branding, connector configuration, terminal types and communication options.

Share your site layout, transformer capacity and expected daily sessions, and our engineering team will size the stack, gun count and liquid cooled terminal configuration for you within 24 hours.
