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
