Abstract: A method for providing supplemental flow control of working fluid through a transport climate control circuit during a start-stop cooling operation mode is provided. The method includes closing a main liquid suction solenoid valve disposed between a condenser and an evaporator of the transport climate control circuit when the compressor is OFF. The method also includes monitoring a climate controlled space temperature within a climate controlled space. When the climate controlled space temperature is greater than or equal to a setpoint temperature, the method includes turning a compressor ON, and opening the main liquid suction solenoid valve when a suction pressure at the suction port of the compressor is less than or equal to a predetermined suction pressure threshold. When the climate controlled space temperature is less than or equal to the setpoint temperature, the method includes turning the compressor OFF, and closing the main liquid suction solenoid valve.

Abstract: A method for notifying and mitigating a suboptimal event occurring in a transport climate control system that provides climate control to a climate controlled space of a transport unit is provided. The method includes monitoring an amount of power available for powering the transport climate control system, monitoring a power demand from the transport climate control system, and accessing operational data of the transport climate control system and the transport unit. The method also includes a controller determining whether a suboptimal event is detected based on one or more of the monitored amount of power available, the monitored power demand and the accessed operational data. Also, the method includes the controller generating a notification when a suboptimal event is detected, and the controller instructing the generated notification to be displayed on a display.

Abstract: Systems and methods are provided for providing predictive energy consumption feedback for powering a transport climate control system. This can include determining whether an energy level of an energy storage source is greater than an expected energy consumption of a transport climate control system during a route, based on route parameters. The route parameters may be obtained via a human-machine interface. When the energy storage source is less than the expected energy consumption, a user is alerted. The systems and methods may further compare the energy level to an expected energy level during transit to determine if the energy level is greater or less than expected and alert the user when the energy level is less than expected.

Abstract: Methods and systems for providing feedback for a transport climate control system are disclosed. The transport climate control system provides climate control to a climate controlled space of a transport unit. The method includes determining, by a controller, a first energy level state capable of providing power to the transport climate control system. The method also includes obtaining, by the controller, status data when a predetermined triggering event occurs. The method further includes determining, by the controller, a second energy level state capable of providing power to the transport climate control system after a predetermined time interval. Also the method includes determining energy consumption data based on the first energy level state and the second energy level state. The method further includes combining the status data and the energy consumption data to obtain feedback data. The method also includes displaying, via a display device, the feedback data.

Abstract: Systems and methods are provided for providing energy consumption feedback for powering a transport climate control system using external data. This can include determining whether an energy level of an energy storage source is greater than an expected energy consumption of a transport climate control system during a route, based on route parameters and route conditions. The route conditions may be obtained from a source such as a remote server, and include data such as weather data, traffic data, or the like. The systems and methods may further compare current energy levels to an updated predictions of energy consumption during transit to determine if the energy level is sufficient to complete the route and alert the user when the energy level is insufficient to complete the route.
