Temperature Controlled Battery Pack Bath Tub (Bpbt), And A Method Of Protecting A Large Battery Pack From Thermal Stresses

Abstract: Temperature controlled Battery Pack; a Method of protecting a large battery pack from thermal stresses; all weather Battery module; an apparatus and method for charging a battery pack, and decoupling the charging voltage from the battery pack voltage; an apparatus and method for discharging the hybrid battery modules, and extending the range of the battery pack; Battery pack controller - safety and reliability of battery pack. A method of providing flood protection to a large battery pack. A method of cooling the battery pack in extreme hot temperatures. A method of heating the battery pack in extreme cold temperatures. A method of repurposing the battery module (BM) Charging and balancing circuit is one of the key components of the battery pack. The invention constitutes an apparatus of Energy discharging split circuit installed within each BM, and an energy management algorithm installed in the battery pack controller. The energy discharging circuit mixes the current output of batteries and capacitors within each BM, as per the instructions from the battery pack controller algorithm. The algorithm takes the SoH and SoC of the batteries in the weakest BMs into account to calculate the mix of current from batteries and capacitors, and selectively instructs each BM. A method for discharging the battery BMs, and extending the range of the battery pack. Battery pack controller is the Master controller of the battery pack.
