High-efficiency, variable-speed refrigerant compressor engineered specifically for advanced Battery Thermal Management Systems (BTMS) in electric buses, commercial vehicles, and large-scale energy storage applications.

The 10kW Electric Compressor serves as a core actuator in direct-cooling or heat pump-based thermal architectures, enabling precise temperature control of lithium-ion battery packs. This is critical for maximizing performance, safety, and service life under diverse operating conditions.

Unlike conventional fixed-speed compressors used in passenger cars, this 10kW unit is optimized for the higher thermal loads and extended duty cycles typical of heavy-duty electric mobility. It supports both cooling and heating modes when integrated into reversible heat pump circuits, making it a versatile solution for year-round battery climate control in extreme ambient environments ranging from -30°C to +50°C.

Developed in alignment with automotive-grade reliability standards, the NEWBASE 10kW compressor combines robust mechanical design, intelligent electronics, and low-GWP refrigerant compatibility to meet the evolving demands of zero-emission transportation.

Equipped with a brushless DC (BLDC) or permanent magnet synchronous motor (PMSM), the compressor delivers continuous cooling capacity of up to 10 kW at nominal conditions. Its speed is electronically controlled via PWM or CAN bus signals, allowing real-time modulation of refrigerant mass flow to match instantaneous battery heat loads.

Variable-speed compressors can reduce energy consumption in BTMS by 20-35% compared to on/off cycling systems, extending vehicle range and reducing auxiliary load on the traction battery.

The 10kW compressor is designed for integration into:

• Direct refrigerant cooling loops with cold plates in direct contact with battery cells
• Reversible heat pump systems that recover waste heat to warm batteries during cold starts

This dual-mode capability supports integrated thermal management to improve winter efficiency in electric buses by up to 40%.

Built for the harsh environment of commercial EVs, the compressor features:

• Hermetic or semi-hermetic housing with reinforced mounting points
• Oil management system compatible with POE or PAG lubricants
• Vibration tolerance exceeding 5g RMS (10-500 Hz)
• IP67-rated electrical enclosure for the inverter and connectors

These attributes ensure reliable operation over 15,000+ hours of service life, even under frequent start-stop cycles and road-induced shocks.

The compressor is validated for use with environmentally compliant refrigerants, including:

• R134a (current standard)
• R1234yf (GWP < 1)
• R744 (CO₂) - available in high-pressure variant for future-ready systems

The onboard variable-frequency drive (VFD) includes:

• Overcurrent, overvoltage, and overtemperature protection
• Stall detection and soft-start functionality
• CAN 2.0B / J1939 communication for integration with BMS and vehicle thermal controllers
• Compliance with ISO 26262 ASIL B for functional safety

The 10kW compressor is deployed in:

• Electric city buses with 200-400 kWh battery packs requiring active cooling
• Battery swap stations needing rapid thermal stabilization
• Commercial delivery vans and trucks operating in hot climates
• Stationary energy storage systems (ESS) requiring industrial-grade thermal control

When paired with NEWBASE's electronic expansion valve, stainless steel plate heat exchanger, and high-voltage PT sensors, the compressor forms a complete, high-efficiency thermal loop capable of maintaining battery temperatures within ±2°C of target setpoints.

The transition to low-GWP refrigerants and energy-efficient compressors is accelerating across the transport sector. The 10kW compressor supports this shift by offering drop-in compatibility with next-generation refrigerants while minimizing parasitic energy loss—a key factor in achieving regulatory compliance for CO₂ emissions from heavy-duty vehicles.
