High-Efficiency 20kW Liquid-Cooled OBC Solution for Electric Loaders

A leading heavy equipment OEM was developing a next-generation electric wheel loader designed for intensive earthmoving and mining operations. Transitioning to a 614V/230Ah high-voltage battery architecture, the manufacturer required a charging solution that could survive the most punishing industrial environments while delivering rapid, reliable power.

• Extreme Durability: Equipment operates in environments with heavy dust, mud, and continuous mechanical shock.
• High-Voltage Requirements: Precise charging management for large-scale 614V LFP battery systems.
• Thermal Stress: Sustained high-power charging (20kW) in outdoor temperatures ranging from -10°C to +55°C.
• Mission-Critical Uptime: Any charging failure leads to costly job-site downtime.

CTS provided an Industrial-Grade 20kW Liquid-Cooled On-Board Charger (OBC), engineered specifically for the duty cycles of construction and mining machinery.

• Core Configuration: 20kW High-Power OBC Unit.
• Ruggedized Enclosure: IP67-rated aluminum alloy housing with enhanced vibration and shock resistance (compliant with heavy-duty machinery standards).
• Advanced Thermal Management: Active Liquid Cooling ensures the power electronics maintain peak efficiency even during 24/7 multi-shift operations.
• Smart Integration: High-speed CAN communication for seamless interaction with the vehicle’s high-voltage BMS and industrial control systems.

• Maximized Operational Uptime: Rapid 20kW charging significantly shortens recharge windows between shifts, keeping the fleet moving.
• Zero-Maintenance Reliability: The IP67 liquid-cooled design eliminates failures caused by dust ingestion or overheating, reducing the Total Cost of Ownership (TCO).
• Future-Proof Electrification: The 614V compatibility ensures the charging system stays ahead of the industry’s shift toward higher voltage architectures.
• Safety First: Integrated protection against over-voltage, short-circuits, and thermal runaway ensures operator and equipment safety.
