Abstract
The present disclosure relates to a method for operating a temperature control system for a temperature controlled goods vehicle, wherein the temperature control system comprises: a solar panel and a temperature control unit comprising: one or more temperature control components; a battery coupled to the solar cell (200) for receiving a first charging current i1 from the solar cell; an engine operative to supply a second charging current i2 to the battery; and a controller. The method comprises: at the controller: monitoring a voltage of the battery; if the voltage of the battery exceeds a first battery voltage threshold for a first predetermined amount of time: determining a first energy count value representing an amount of energy delivered by the solar panel in a predetermined time period; if the first energy count value exceeds a first energy count value threshold: determining an average current value representing an average amount of energy delivered by the solar panel in the predetermined time period; and increasing a cycle threshold value that determines when the engine is deactivated so as to stop supplying the second charging current i2 to the battery based on the average …
