1. An energy storage system for an electric vehicle, the energy storage system comprising a first energy storage source that includes:
an ammonia tank configured to hold ammonia;
an ammonia converter configured to receive ammonia from the ammonia tank and convert the received ammonia into hydrogen; and
a fuel cell system communicating with the ammonia converter and configured to generate output power from hydrogen that is received from the ammonia converter,
where the first energy storage source further includes a power conditioning system that communicates with the fuel cell system and regulates the output power of the fuel cell system,
wherein the energy storage system further comprises:
a second energy storage source, the second energy storage source including a battery; and
a third energy storage source, the third energy storage source including a supercapacitor, the supercapacitor being connected with the battery in parallel,
wherein the fuel cell system is configured to provide controllable electric power to the battery or the supercapacitor via the power conditioning system.
