A refrigeration system having a refrigeration unit () for providing temperature conditioned air to a temperature controlled space, an engine () and an electric generation device () driven by the engine, is provided with a battery system () for supplying electric power. A method of operating the transport refrigeration includes, during a high cooling demand mode, operating the engine () to drive the electric generation device () for supplying electric power and simultaneously employing the battery system () for supplying electric power to jointly power the plurality of power demand loads () of the refrigerant unit.

Transport refrigeration system and method for operating

A power supply system for a transport refrigeration system includes an engine coupled to a compressor of a refrigeration unit for direct drive powering the compressor and a generator arranged to also be direct driven by the engine for generating electric power. The generator and the compressor are mounted to a common drive shaft driven by the engine, and the generator may be integrated with the compressor. The power supply system may further include an alternator arranged to be belt driven by the engine for generating DC electric power. A battery pack may be provided for storing and supplying additional DC power. During peak load demand on the refrigeration unit, the engine may be operated with the generator switched off to directly drive the compressor and direct current may be drawn from the battery pack to drive the condenser/gas cooler and evaporator fans.
