Patent ID: 11821661

Abstract:
A transport refrigeration unit (TRU) system is provided. The TRU system includes a TRU and an energy storage device (ESD). The TRU includes components (32) configured to control an environment in a compartment interior and a TRU controller (31) configured to control the components (32) in accordance with initial control settings and to monitor energy usage by the components (32) being controlled in accordance with the initial control settings. The ESD (40) includes an ESD controller (42) receptive of data reflective of the monitored energy usage by the components (32) from the TRU controller (31) and configured to determine whether the energy usage is above a threshold. In an event the energy usage is above the threshold, the ESD controller (42) is further configured to identify operational changes for one or more of the components (32) to reduce the energy usage and override the initial control settings of the one or more of the components (32) with new control settings.
