TRACTOR TRAILER REFRIGERATION UNIT
First Claim
1. In a self-contained vehicle power system, an electrical controller device for powering a transport vehicle based load, comprising:
- a propulsion vehicle source driven by a native propulsion source of the vehicle;
a passive vehicle source disposed on the vehicle and adapted for providing power independently of vehicle motion or engine state;
a vehicle based load responsive to power from the propulsion vehicle source or the passive vehicle source;
an interface to a native vehicle load, the interface for powering the native vehicle load concurrently with the vehicle based load;
a refrigeration load for maintaining an ambient temperature in a cargo payload area of the vehicle;
a storage element configured for accumulating excess power for subsequent dispersal to the vehicle based load;
the controller operative for converting between different voltage characteristics of at least the propulsion vehicle source and the refrigeration load.

Abstract
A reefer truck power unit employs a plurality of power sources including: a propulsion vehicle source driven mechanically by a diesel engine of the vehicle, and having an enhanced alternator configured for generation in excess of needs of a charging/starting system of the vehicle, in which the enhanced alternator has a pulley ratio increasing idle speed generation, and a passive vehicle source including a bank of solar panels disposed on the vehicle. The refrigeration system is configured for refrigerating a payload area of the vehicle utilizing power from the power sources, and employs a voltage converter for augmenting the power from the propulsion vehicle source for use with a native vehicle charging/starting system, and a transport load transformer for converting power from the power sources to 3 phase power for powering the refrigeration system. A bank of batteries stores power from the sources for subsequent dispersal to the refrigeration unit.
