Early Warning for Li-Pos

Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

Nobody wants an airplane fire.  You’re way up in the air, can’t pull over to the curb, and have limited means of quelling the flames.  The most energy-dense batteries, based on lithium chemistries, are subject to failure from physical and electrical abuse.  Most cells run through their promised cycle life without giving a hint of trouble, but sometimes fate or mischance leads to disaster. Battery alternatives with lower risk usually possess lower energy and/or power density, crucial to use in aircraft, since weight is usually a primary consideration in vehicle design. Lithium fires are quite often spectacular, probably a consideration that prompts Dale Kramer to recharge his 100 pounds of cells in his fireplace – with the flue wide open.  …
