This abstract first appeared for US patent application 17984605 titled 'SYSTEM AND METHOD ESTIMATING TEMPERATURE OF A DIRECT CURRENT BUS BAR AND DIRECT CURRENT CONNECTOR IN A POWER INVERTER AND PROVIDING CONTROL BASED UPON THE TEMPERATURE

==Simplified Explanation==

The patent application describes a system that includes a battery providing electrical energy in direct current, a drive unit utilizing electrical energy in alternating current to provide output torque, and a power inverter transforming the electrical energy from DC to AC for the drive unit. A computerized controller monitors the environmental temperature of the inverter and the current flow of the electrical energy, determining the estimated temperature of the bus bar and the inverter's available capability based on this information. The controller then compares the capability to a threshold value and controls the drive unit accordingly.
