Patent for Sale:Technology for High Current (700A), Rapid Charging Battery Module
Primary Application of the Technology
Battery modules for electric grid storage
The Problem Solved by the Technology
How the Technology Solves the Problem
1 - Enables fast charging, 20 minute or less, of high capacity batteries that afford a 300 mile driving range. The current, level 3, rapid-charge technologies under discussion typically charge small/medium batteries in 30+ minutes, affording a 100-120 mile driving range.
2 - Provides superior thermal management for existing Lithium Ion cells. A battery manufacturer can use this technology to repackage their cells into modules that provide better thermal management, thus improving on safety and increasing the lifetime of the module.
3 - Battery modules that use this technology can be repeatedly rapid charged and discharged without exceeding thermal limits, thus enabling a driving range of over 900 miles in a single day; in contrast, existing technologies require a cooling-down or recycle time of several hours, effectively only allowing one charge per day.

Class 320: Electricity: Battery Or Capacitor Charging Or Discharging
Method or apparatus for controlled or regulated charging, discharging, or combined charging and discharging of one or more voltaic cells, batteries, or capacitors. Charging or electrically rejuvenating (e.g., depolarizing, etc.) a voltaic cell, battery, or electrical capacitor, wherein said charging or rejuvenating is accomplished by controlled addition of electrical energy into the cell, battery, or capacitor. Discharging - a voltaic cell, battery, or electrical capacitor, wherein discharging is accomplished by controlled release of electrical. A cell, battery, or capacitor structurally combined with a generator or electrical converter, whether or not electrical interconnection therebetween is recited.Subclass 112: For battery pack
