METHOD FOR CALIBRATING A PLURALITY OF CURRENT SENSORS, BATTERY SYSTEM: abstract simplified (18186317)

• This abstract for appeared for patent application number 18186317 Titled 'METHOD FOR CALIBRATING A PLURALITY OF CURRENT SENSORS, BATTERY SYSTEM'

Simplified Explanation

The abstract describes a method for calibrating multiple current sensors that are connected in series. The method involves determining the temperature difference between the sensors, measuring temperature and current values of each sensor at different temperatures and currents, calculating averaged current values for two sensors based on the measured values, calculating a current regression area for each sensor based on temperature and current deviations, and calculating a TCR (temperature coefficient of resistance) regression curve or area for each sensor based on the intersection and deviation of the current regression areas and the temperature difference between the sensors.

Original Abstract Submitted

A method for calibrating a plurality of current sensors connected in series. The method include determining a temperature difference between the current sensors; sensing temperature values and current values of the respective current sensors at different temperatures and currents; calculating averaged current values of two current sensors based on the current measured values sensed by the respective current sensors; calculating a current regression area for the respective current sensors through measurement points that are dependent on the temperature of the respective current sensors and the deviation of the current values sensed by the respective current sensors relative to one another; and calculating a TCR regression curve or a TCR regression area for the respective current sensors based on a deviation and an intersection curve of the respective current regression areas relative to one another and/or relative to an averaged current regression area and a temperature difference between the current sensors.
