1. A tow vehicle comprising:
a vehicle body;
a turntable lifting unit coupled to the vehicle body and configured to engage with an aircraft nose landing gear;
a modular high-current battery management system comprising:
at least one removable battery pack module housed within the vehicle body, the at least one removable battery pack module comprising:
a battery frame housing a plurality of lithium iron phosphate (LiFePO4) batteries;
a controller configured to monitor and control the plurality of batteries;
a high-current DC power relay for managing current flow;
at least one supercapacitor configured to manage rapid changes in current flow; and
at least one semiconductor device configured to regulate voltage and current levels;
wherein the modular high-current battery management system is capable of providing a peak current output of at least 1000 amperes; and
a drive system powered by the modular high-current battery management system and configured to move the tow vehicle.
