- Description
- NASA�s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology.� License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use.��NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: A battery charge equalizer developed at NASA's Johnson Space Center provides individual cell charging in multi-cell battery strings using a minimum number of transformers.� By effectively keeping all the cells in a multi-cell string at the same charge state, this technology maximizes the battery's life and performance. Designed to augment a simple high-current charger that supplies overall battery system energy, the innovation achieves equalization without wasting energy or creating excess heat.� NASA's battery charge equalizer complements existing high voltage chargers and instrumentation systems and offers safe and low-cost management for lithium-ion (Li-ion) batteries used in electric vehicles and other next-generation renewable energy applications.� This NASA Technology is available for your company to license and develop into a commercial product.� NASA does not manufacture products for commercial sale. The innovation consists of a transformer array connected to a battery array through rectification and filtering circuits. The transformer array is connected to a drive circuit and a timing and control circuit, which enables individual battery cells or cell banks to be charged.� The timing and control circuit connects to a charge controller that uses battery instrumentation to determine which battery bank to charge.� The system is ultra lightweight because it uses much fewer than one transformer per battery cell.� For instance, 40 battery cells can be balanced with an array of just five transformers.� The innovation can charge an individual cell bank at the same time while the main battery charger is charging the high-voltage battery system. Conventional equalization techniques require complex and costly electrical circuitry to achieve cell monitoring and balancing.� Further, such techniques waste the energy from the most charged cells through a dummy resistive load (regulator), which is inefficient and generates excess heat.� In contrast, this system equalizes battery strings by selectively charging cells that need it.� The technology maintains battery state-of-charge to improve battery life and performance.� In addition, the technology provides a fail-safe operation and a novel built-in electrical isolation for the main charge circuit, further improving the safety of high-voltage Li-ion batteries. To express interest in this opportunity, please submit a license application through NASA�s Automated Technology Licensing Application System (ATLAS) by visiting https://technology.nasa.gov/patent/MSC-TOPS-35 If you have any questions, please contact NASA Johnson Space Center�s Technology Transfer Office at jsc-techtran@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information.� For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at https://technology.nasa.gov/ These responses are provided to members of NASA�s Technology Transfer Program for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities.��No follow-on procurement is expected to result from responses to this Notice.
