METHOD AND APPARATUS FOR REGULATING THE HYDRATE FORMATION TEMPERATURE IN A METAL-HALOGEN BATTERY

摘要

Temperature control mechanism takes the form of discrete electronic circuit or programmed digital computer for accurately regulating the temperature of a hydrate forming solution in a metal halogen battery during charge. The electronic circuit and/or digital computer senses the actual solution temperature, by measuring the temperature of coolant circuit in thermal communication therewith. The actual temperature is compared with a set point temperature based on curve fitting algorithm for approximating the hydrate formation temperature which changes during charge. For sufficiently large differences between actual and set point temperatures, an electrical impulse is applied to servo driven mixing value to selectively increase or decrease flow of chilled coolant to the coolant circuit.
