System and method of controlling compressor, evaporator fan, and condenser fan speeds during a battery mode of a refrigeration system for a container of a vehicle

A system comprising:

• a mode module configured to, based on a plurality of parameters, determine whether to operate in a shore power mode, an engine mode, or a battery mode, wherein one or more batteries are charged based on received utility power while in the shore power mode, and wherein the one or more batteries, while in the engine mode, are charged based on power received from an alternator or a generator;
• and
• a battery module configured to, while operating in the battery mode,
• determine a first speed based on (i) a temperature within a temperature controlled container of a vehicle, and (ii) a state of charge of the one or more batteries, and
• run a compressor at the first speed,
• wherein, while in the battery mode, the one or more batteries are not being charged based on power from (i) a shore power source, and (ii) the alternator or the generator from which power is received during the engine mode.
