An energy efficient and highly versatile electrically-powered air conditioning and heating system for mobile vehicles. Multiple variable-speed compressors operate in series and parallel modes giving an exceptionally wide range of operating capacity making the system suitable for combined on-highway and no-idle use in trucks. In series mode, the single-stage compressors function like a two-stage compressors for increased energy efficiency. A unique power control and storage system has multi-voltage input and output capability without the use of DC-DC or DC-AC converters. A battery management system is incorporated which is compatible with all advanced battery technologies and offers cell-level charge and discharge control.
