A new all-electric air-conditioning (AC) system has been engineered by Germany-based automotive supplier Eberspaecher for hybrid and battery-electric driven buses in the Asia-Pacific region.

Market forecasts indicate that by 2030, 40% of the bus fleet in India will consist of battery-electric vehicles. In this context, the Indian market is considered a pioneer of a global trend: the electrification of public transport with a focus on large cities. To meet the requirements of the market, Eberspaecher developed the AC135 AE platform as an all-electric AC system for hybrid and battery-electric driven buses for customers inSource: EberspaecherSource: Eberspaecher India, the Middle East and Asia.

This thermal management system for large and mid-size buses includes an integrated inverter, battery thermal management and customer-specific software. The energy efficient product platform of the AC135 AE is available in different versions providing heating and cooling performance levels from 30 kW to 40 kW. An optimized condenser and improved heat exchanger design translates into significant reduction of weight, refrigerant (up to 15%), power and fuel consumption as well as an increased efficiency of the AC system.

As with previous product generation, all performance variants are equipped with the same interface for an easier on-roof installation and reduced roof structure variances. Five product variants with different heating and cooling performance levels allow the use in all regions of the world: The AC353-545, for example, is suited for areas with hot and tropical climates.
