Current allocation system and method for utility vehicles

A battery management system comprising:

• a memory storing instructions;
• and
• a controller designed to execute the instructions to cause the battery management system to:
• determine at least one operating condition associated with a battery, the at least one operating condition including a total active current draw of at least two inverters connected to the battery;
• determine a threshold current draw for the at least two inverters based on the at least one operating condition;
• compute a spare current as a difference between the total active current draw and the threshold current draw;
• compute respective current allocations of the spare current for the at least two inverters based on the at least one operating condition;
• and
• output at least one command imposing current limits on the at least two inverters based on the respective current allocations.

A method comprising:

• determining at least one operating condition associated with a battery of an electric utility vehicle, the at least one operating condition including a total active current draw of at least two inverters connected to the battery;
• determining a threshold current draw for the at least two inverters based on the at least one operating condition;
• computing a spare current as a difference between the total active current draw and the threshold current draw;
• computing respective current allocations of the spare current for the at least two inverters based on the at least one operating condition;
• and
• controlling the at least two inverters to operate according to the respective current allocations.
