During winter testing in northern China, these buses achieved stable heating performance even at -25°C, with a coefficient of performance (COP) exceeding 2.5—significantly higher than conventional PTC heaters. This not only extended the driving range by an average of 12% but also reduced charging frequency, directly lowering total cost of ownership for operators. Additionally, the system supports dual-mode operation: cooling via R744 carbon dioxide refrigerant (a zero-GWP solution) and heating through transcritical heat pump cycles, making it ideal for eco-conscious transit agencies. The success of this pilot led to a follow-up contract worth $28 million, securing long-term supply agreements for 2,000 buses. Moreover, the system’s ability to recover waste heat from battery packs and motors further enhances overall energy utilization, aligning with global decarbonization goals. These results underscore Newbase’s leadership in delivering sustainable, high-efficiency thermal management solutions tailored for modern urban transit fleets.
