Transport climate control specialist Thermo King, a brand of Trane Technologies, has introduced a new heat pump for battery-electric buses operating in moderate and colder climates.
Part of Thermo King’s all-electric TE Series product line, the new TE Series Heat Pump enables fleet operators to extend bus range, further reduce emissions and maintain passenger comfort.
Electric resistance heaters significantly reduce operating range by drawing substantial amounts of energy from vehicle batteries. The TE Series Heat Pump applies Trane’s expertise in heat pump technology, which has been applied across commercial buildings and homes, to public transit applications.
The TE Series Heat Pump extracts heat from ambient air rather than generating heat from battery power, delivering up to 2.5 times more energy efficiency than resistance heaters, which translates to more miles per charge. Thermo King says buses equipped with the TE Series Heat Pump can achieve up to 50% more range at moderate temperatures (40° F) and up to 30% more range at colder temperatures (20° F) compared to those using resistance heaters.
The system effectively keeps passengers warm at temperatures as low as 20° F without the need for backup heating. In colder climates requiring auxiliary heat, the TE Series Heat Pump allows for extended bus routes and reduced reliance on battery recharging.
“This product is a critical step in continuing to make public transportation more efficient, reliable and eco-friendly, proving that decarbonization and operational excellence can go hand in hand,” said Chris Tanaka, VP of Product Management for Thermo King Americas.
