Thermo King, a brand of Trane Technologies, has introduced the TE Series Heat Pump, a new addition to its all-electric, high-efficiency TE Series for battery-electric buses. Designed for use in moderate and colder climates, the system aims to reduce emissions and extend bus operating range without compromising passenger comfort.
Traditional electric resistance heaters in battery-electric buses can draw substantial energy from vehicle batteries, reducing range. Thermo King’s TE Series Heat Pump leverages Trane Technologies’ heat pump expertise to extract heat from ambient air, improving energy efficiency and reducing battery drain. According to the company, this technology can deliver up to 2.5 times the efficiency of conventional electric resistance heaters.
The system enables buses to achieve up to 50% more range at moderate temperatures (around 4°C / 40°F) and up to 30% more range at colder temperatures (around -6°C / 20°F) compared to vehicles using traditional resistance heaters. It also operates effectively at approximately -6°C (20°F) without requiring backup heating.
The TE Series Heat Pump incorporates automated control strategies for heating, auxiliary heating and defrost functions, reducing driver input and ensuring consistent passenger comfort. It is compatible with existing TE Series systems, minimizing additional training for fleet operators and technicians.
“This product is a critical step in continuing to make public transportation more efficient, reliable and eco-friendly,” said Chris Tanaka, vice president of product management for Thermo King Americas. “By applying heat pump expertise, we are equipping fleet operators with innovative solutions that extend beyond emissions reduction alone.”
