300kW Heavy-Duty DC Fast Charger | Outdoor Fleet & Bus/Truck EV Solution

Introducing CMX Battery 300kW Heavy-Duty DC Fast Charger

Most fleet operators don’t struggle with “charging speed on paper.” The real challenges are vehicles waiting too long to charge, different connector standards across fleets, chargers failing in outdoor environments, and no visibility when something goes wrong.

This charger is designed to reduce those operational risks—not by chasing theoretical peak numbers, but by delivering what actually matters for fleets: uptime, compatibility, and predictable performance.

It supports both current 400V and next-generation 800V vehicles across a wide 150–1000VDC range, with up to 300kW output. One unit can accommodate CCS1, CCS2, GB/T, and optional CHAdeMO, so mixed fleets don’t require separate infrastructure.

Rated IP55 for outdoor use, it operates reliably from -40°C to 75°C. OCPP 1.6 with remote monitoring gives you real-time visibility into status, usage, and fault alerts. The floor-mounted, bottom-cable-entry design simplifies depot installation.

This is not a universal solution for every scenario. It is a reliable, configurable system built specifically for fleet charging environments—where operational continuity matters more than specs on paper.

Key Advantages

High Power Charging (Up to 300kW)

• Output power: up to 300kW
• Voltage range: 150–1000VDC

What this means in practice:

Charging performance depends on the vehicle battery and BMS. Typically used to add energy during operational windows such as loading, driver breaks, or depot stops.

Multi-Standard Compatibility

CCS1 / CCS2
GB/T
CHAdeMO 2.0 (optional)

The 300KW Heavy-duty DC fast charging staion can support mixed fleets, reducing the need for separate charging infrastructure.

Outdoor Deployment (IP55)

Protection rating: IP55
Operating temperature: -40°C to 75°C

Suitable for outdoor installation in most environments
(Note: output may derate under extreme temperatures, which is normal for high-power systems.)

What You Should Know Before Buying

• Charging speed depends on vehicle type — battery voltage, capacity, and state of charge affect time.
• High-power chargers need proper site power — ensure your depot or station can handle 300kW loads.
• Extreme temperatures may affect output — standard behavior for all EV chargers.
• Fleet-specific setup is essential — configure based on vehicle mix, daily mileage, and operational windows.
• Remote monitoring & OCPP improve efficiency — track usage, prevent faults, and optimize charging schedules.
• Future-proof your fleet — choose multi-standard, high-voltage-compatible chargers to avoid costly upgrades.
