A power management method used for power distribution in a transportation refrigeration unit. The power management method includes calculating engine power according to engine operating parameters; calculating power generator real-time input power according to power generator excitation current; calculating available power based on the power generator real-time input power and the engine power; and managing power distributed to a compressor based on the available power. The present invention further relates to a power management system. The power management method and system have the advantages of simplicity, reliability, stable operation and the like, the power generator real-time input power can be calculated according to the power generator excitation current, thus more power can be provided to the compressor on the premise that the power supply to power generator loads is guaranteed, and the operating efficiency of the transportation refrigeration unit is improved.

Power managing method and system for transportation refrigeration unit

A tool assists with maintenance of a belted sheave system. The sheave system includes a belt, a support structure, and a rotational component including a housing detachably engaged to the support structure and a sheave mounted for rotation to the housing and about an axis. The tool includes a rod constructed and arranged to rigidly mount to the support structure with a centerline disposed substantially parallel to the axis. A bracket of the tool is constructed and arranged to be engaged to the housing and is in sliding contact with the rod.

Tool for use with a belted sheave system and method of use

An energy harvesting system is provided. The energy harvesting system includes a transport refrigeration unit (TRU), a remote wireless element operably disposed to respond to a characteristic of the TRU and an energy harvesting circuit. The remote wireless element includes a battery and a response element powered by the battery. The energy harvesting circuit is coupled to the battery and configured to generate electricity from TRU movements. The electricity generated from the TRU movements is provided to at least one of the remote wireless element to power operations of the remote wireless element and the battery to charge the battery.
