  "textContent": "A power system for a transport refrigeration unit (200) of a vehicle, and a method of powering a transport refrigeration unit (200) of a vehicle are described. [0002] The power system for a transport refrigeration unit (200) of a vehicle comprises: a battery unit (280) configured to supply electrical power to a refrigeration system of the transport refrigeration unit (200); a generator (240) configured to charge the battery unit (280); an engine (250) configured to drive the generator (240); and a control system (220). The control system (220) is configured to: receive or determine a vehicle route from a current location of the vehicle to a destination of the vehicle; predict how a power level of the battery unit (280) will change on the vehicle route; and control an operational state of the engine (250) based on the vehicle route and the predicted power level. In this way, fuel may be preserved, by operating the engine only when required, and hence the cost of transporting refrigerated goods may be reduced.",
