1. A method for regulating an energy storage device comprising at least one electrochemical cell comprising a negative electrode, positive electrode and an electrolyte between said negative and positive electrodes, the method comprising:
(a) measuring, with the aid of a temperature sensor in thermal communication with said electrochemical cell, an operating temperature of the electrochemical cell, wherein at least one of said negative electrode, positive electrode and electrolyte are in a liquid state at said operating temperature; (b) calculating, with the aid of a battery management system, an impedance of a current flow path leading through said electrochemical cell using a correspondence between impedance and temperature stored in a memory location of said battery management system; and (c) calculating, with the aid of said battery management system, a state of charge of said electrochemical cell using said impedance calculated in (b) and a current measured through said electrochemical cell. |
