BATTERY SAFETY @ PWRJoule
Safety is Priority Number One
Battery safety is the primary driver at PWRJoule. Safety is managed through multiple layers of design including both hardware and software protections. Safety and thermal management are a major part of design and testing. Our magnetic flow battery chemistries are water-based and non-flammable. Our battery systems contain multiple layers of safety at the cell, module, battery and system levels. These levels of control also ensure optimal battery performance to maximize total life cycle cost. This is accomplished using a proprietary battery management system (BMS) developed specifically for PWRJoule magnetic flow battery technology.
Avoid Lithium Battery Hazards
Batteries present both electrical and chemical hazards. Standard lithium-ion batteries are not suitable for large-scale applications such as electrical utility grid energy storage. There have many battery fires and safety recalls with lithium batteries. The batteries must be significantly scaled up in size to support large installations. As a result, the safety issues and potentially devastating safety effects from incidents also scales up accordingly.
Fault Tolerant Technology
A particular problem with lithium batteries is that they are subject to thermal runaway and cell-to-cell propagation of thermal runaway. An internal short-circuit or fire can start in just one cell and quickly engulf the entire battery. This has been observed many times in commercial applications like electric vehicles. PWRJoule technology is not subject to thermal runaway and faults will not propagate through the entire battery system.
THE TEAM
Bret Raymis - CEO, Co-Founder and Executive Board Member
Bret has a vast array of experience in developing new technologies and business. Bret's foundation started in the US Army as an Avionics technician working on UH-1H helicopters. As a vet, Bret was hired by Bell Laboratories in Allentown, PA. to start his career in electronics.
Bret has extensive background in business. His entrepreneurial spirit started out by mowing neighborhood yards as a teenager. Bret was a primary founder to a startup Solar Power Technologies in Austin, TX that raised over $25M. Bret has held director seats on multiple boards. He recently served on the finest and oldest environmental nonprofit organization I Love a Clean San Diego.
Bret can adapt to almost any environment. Bret is willing to help wherever necessary to move the company in a positive direction.
Bret has also developed a multitude of flows for physical design. Bret's design flows included many technologies and software tools. Bret stream lines the process into an efficient technique and then teaches for peers.
Bret is well versed in highly technical and complex engineering of integrated semiconductors circuits. Bret has worked on some of the most profitable products in the world. Many of his circuit designs have grossed over $500M. They include the first audio and sound chips for Apple and Commodore Computers. Bret's layouts have been on Qualcomm's very successful Snapdragon 800 series processors for mobile phones. Bret has lead teams for over 50 integrated circuit chips in his career.
Bret has been CEO and board member of PWRJOULE LLC for almost 3 years. During his lead, the company has bootstrapped the company from technology readiness level 1, (TRL), to current TRL 3. PWRJOULE has two provisional patents for our magnetic particle flow battery. PWRJOULE has a team of excellent engineers poised to step up to full time positions upon major funding due to equity.
William “Bill” Nunnally - VP of Engineering, Co-Founder and board member
Bill has been a leader in the field of electronics. Bill has held many prestigious positions such as staff member position at Los Alamos, a professor of electrical engineering role at UT, a director at UT for Applied Physical Electronics Research Center, a faculty member at Lawrence Livermore National Laboratory, a professor of electrical engineering at University of Missouri, and consultant for numerous high-tech companies.
Just prior to PWRJOULE, Bill was primary Chief Scientist at Applied Physical Electronics for 11 years creating high power electro-magnetics, high power antennas, pulsed power systems, high power lasers and laser applications, optics and integrated optics, magnetic pulse compression and magnetic switches, pulse transformers, spark gap (oil, water, gas and multi-channel gas)switches , HV (tens of kV) photo-conductive switches, electro-magnetic (coil, rail, and hybrid) launchers, GHz transient diagnostics and Lithium Ion Micro Particle Fuel Cells.
Bill is the primary technology officer behind the magnetic particle flow battery, MPFB. It has been Bill’s idea for many years to create a MPFB that would be safer, longer lasting and less expensive type battery than current lithium technology.
Bill has tirelessly devoted thousands of hours on experiments in his garages to take the IP from TRL1 to TRL3. Bill has supported PWRJOULE in funding and as a board member for more than 3 years.
