480kW 720kW Flexible Shared Charging Stack 600A Liquid Cooled Terminal 40kW SiC Module for Fleet Charging Hub

A charging stack that grows with the site. The 480kW / 720kW power pool converts a fixed transformer capacity into a flexible resource: 40kW SiC modules feed a shared DC bus, and the energy management system routes power to whichever vehicle needs it. Paired with 600A liquid cooled terminals and 2015 / Chaoji connectors, the station is ready for both today's vehicles and the next generation of ultra-fast models.

• 480kW to 720kW power pool: start with the transformer capacity you have and expand module by module as traffic grows.
• Up to 8 charging guns: several vehicles charge at the same time from one cabinet instead of one charger per bay.
• 600kW single gun maximum: ultra-fast top-ups deliver roughly 200km of range in about 3 minutes on capable vehicles.
• 40kW SiC modules: silicon carbide power stages reach 97 percent or higher peak efficiency and cut conversion losses at partial load.
• 40kW allocation granularity: power is released in 40kW steps, so no vehicle holds capacity it cannot use.
• Power factor 0.99 or higher: low harmonic impact on the site transformer, reducing upgrade cost.
• 600A liquid cooled terminal: sealed coolant loop keeps cable and connector temperatures low during sustained 600kW sessions.
• 2015 and Chaoji compatible: supports current GB/T vehicles and the new Chaoji ultra-fast standard in one terminal family.
• IP54 cabinet, -30°C to 85°C: handles dust, rain, heat and cold, with automatic derating at high ambient temperature.
• Flexible connectivity: RFID card, GPRS, RS485, CA and Ethernet links with OCPP 1.6 for back-office integration.
• 5M / 10M cable options: reach charge ports on trucks and buses without mechanical strain.
• Altitude 2000m and 5%-95% humidity: rated for highland sites and humid coastal conditions without condensation.

• Shared DC bus: all 40kW modules feed one bus, so capacity follows demand instead of sitting idle behind a dedicated gun.
• Dynamic dispatch: the controller assigns 40kW blocks to active sessions, prioritising vehicles with high state of charge acceptance.
• Peak management: total site draw can be capped to the transformer rating while all bays stay available.
• Expansion without downtime: additional modules or terminals are added to the same cabinet as traffic increases.

• Short circuit and overcurrent protection on every output branch.
• Earth leakage monitoring on AC input and DC output circuits.
• Emergency stop buttons at the cabinet and each terminal.
• PC flame retardant housing and insulated busbar compartment.
• Liquid cooling loop monitoring with leak, pressure and temperature alarms.
• High temperature derating and automatic shutdown to protect modules and cables.

• Fleet charging hubs and logistics depots
• Highway super charging plazas
• Bus depots and taxi ranks
• Commercial parks and large public parking facilities

Gun count, terminal type, connector mix, cabinet branding, interface language and back-office protocol can be configured per project. We support single line drawings for site approval, factory acceptance testing and commissioning guidance for CPO and fleet operators.

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.
