The heat exchanger is a three-medium heat exchanger with phase change material (PCM) stored in the external fin tubes. It allows the refrigerant flowing inside the internal fin tubes and the air to
Output Current Estimation and Control in Primary Side LCC Secondary Side Series Compensated Wireless
Wireless charging of electric vehicles require the ability to control the output current in the power transfer system, but that is often not possible as the availability of signals from the secondary side to the primary side is difficult and not always feasible.
Lean-burn natural gas (NG) engines are a preferred choice for the hard-to-electrify sectors for higher efficiency and lower NOx emissions, but methane slip can be a challenge.
This invention utilizes a salt and an amine containing small molecule or polymer for the synthesis of a bulky anionic salt or containing single-ion conducting polymer electrolyte for the use in Li-ion and beyond Li-ion batteries.
The incorporation of low embodied carbon building materials in the enclosure is increasing the fuel load for fire, increasing the demand for fire/flame retardants.
This invention presents a multiport converter (MPC) based power supply to charge the 12 V and 24 V auxiliary batteries in heavy duty (HD) fuel cell (FC) electric vehicle (EV) power train.
Next generation batteries for electric vehicles (EVs) and other manufacturing needs require solid-state batteries made with high-performance solid electrolytes. These thin films are critical components but are difficult to manufacture to meet performance standards.
Electrolysis is common in the production of clean hydrogen used to produce other chemicals such as ammonia, based on heavy use of precious metals, not mined domestically. Typical electrolyzer components prone to degradation and are not suited for long-term durability.
An ORNL invention proposes using 3D printing to make conductors with space-filling thin-wall cross sections. Space-filling thin-wall profiles will maximize the conductor volume while restricting the path for eddy currents induction.
Technologies are described that are directed to cost-effective and safe deployment of propane as a refrigerant for heat pump water heaters.
