System for assuring safe operation of batteries

System for assuring safe operation of batteries

A system for assuring safe use of a battery pack includes a display unit and a state of health (SoH) monitor connected to the battery pack, the SoH monitor. The SoH monitor a) instructs the SoH monitor to measure terminal voltage of the battery pack at a beginning of a current flow cycle; b) instruc...

description A system for assuring safe use of a battery pack includes a display unit and a state of health (SoH) monitor connected to the battery pack, the SoH monitor. The SoH monitor a) instructs the SoH monitor to measure terminal voltage of the battery pack at a beginning of a current flow cycle; b) instructs the SoH monitor to measure terminal voltage of the battery pack after completion of the current flow cycle; c) instructs the SoH monitor to successively re-measure terminal voltage of the battery pack after completion of the current flow cycle until one of the successively re-measured terminal voltages is equal to a previous one of the re-measured terminal voltage; d) instructs the SoH monitor to determine and record ampere-hours (Ah) passing through the battery pack during the time period between steps a) and c); e) instructs the SoH monitor to determine SoH of the battery pack as a function of a quotient of a difference between terminal voltages determined in steps a) and c) divided by the Ah determined in ste
