Renewable Energy Expert Witnesses

Renewable Energy Technologies

Renewable energy technologies include solar-, wind-, and rechargeable battery-powered systems and contain electronics and software. When an energy generation, storage, or transfer system malfunctions the results can be deadly, especially in a high-voltage situation, as well as lead to blackouts and other adverse effects. Barr Group is in the business of designing reliable and secure embedded systems and our expert software engineers, electrical engineers, and mechanical engineers are well acquainted with the design of energy-related systems and products such as:

• Hybrid and electric vehicles (EV) and their traction battery packs
• Laptop, cell phone, implantable medical, and e-cigarette batteries
• Battery recharging algorithms and charge-sensing electronics
• Inductive charging, a.k.a. wireless charging, including Qi and PMA
• Lithium and Li-ion batteries, charging and storage safety
• Supercapacitors and ultracapacitors 
• Fuel cells, including hydrogen
• Battery chemistry and electrochemical energy storage
• Electrochemistries from alkaline to NiMH, NiCd, NiZn, and ZnBr
• Battery mass production and quality control, including factory setup
• Battery failure analysis and fire safety considerations
• Biomass thermophysical conversion technologies
• Energy generation, storage, and transfer, in general
• Wind and oceanic wave energy capture such as wind farms and turbines
• Solar photovoltaic (PV) cells, panels and systems (including in orbit/space)
• Space propulsion systems, including lunar dust extraction and utilization
• Smart grid technologies for high-voltage energy distribution networks
• Voltage Stability Monitoring & Control (VSMC) software
• Advanced Metering Infrastructure (AMI), a.k.a. "smart meters"

Barr Group's electronics and software experts are familiar with all of the technologies used in battery recharging and renewable energy systems.  This includes FPGAs and ASICs programmed in Verilog and VHDL, processors such as ARM cores programmed in assembly, C/C++, and other languages, as well as Linux and real-time operating systems like VxWorks.  And we are just as comfortable with other tools such as MATLAB and LabVIEW.
