Battery
Don’t put batteries in the crumple zone,
says automotive expert
Some of the most pressing problems associated with powering electric vehicles have more to do with where batteries sit in the chassis than how much juice they provide. So says Bob Galyen, CTO of lithium-ion battery maker Contemporary Amperex Technology Ltd. (CATL) and President of Business Development Amperex Technology Limited in China. Galyen also chairs […]
Lithium charger development kit includes preloaded charge profiles
Delta-Q Technologies, a leader in battery charging solutions for electric drive vehicles and industrial equipment, today announced the debut of its lithium integration kit to battery companies, original equipment manufacturers (OEMs), and battery management system (BMS) manufacturers at The Battery Show in Novi, Michigan. With the goal of supporting lithium powertrain system development, Delta-Q’s lithium […]
Nickel metal hydride battery withstands high temperatures
A high-temperature, long life type Nickel Metal Hydride battery (BK1100FHU, with a Ambient discharge range of -40° C to 85° C) is said to be suitable for applications requiring high capacity and a wide range of temperatures. Samples are anticipated to be available December 2016. Developed by Panasonic, the battery targets uses in a variety […]

Battery-charging considerations for low-power applications
By Tahar Allag The wearable and personal-electronics industries are booming. Devices in this market vary wildly by application and use. These multifunction devices are designed to help people in their daily activities and make their lives comfortable. They can be found in different shapes, colors, sizes, and safety measures. They may differ significantly from each […]
Lithium Nickel Manganese Cobalt Oxide
batteries help solar plane circle the globe
Ultra-high-energy Lithium Nickel Manganese Cobalt (NMC) Oxide battery technology is being credited with helping the Solar Impulse 2 plane complete its trip around the world using only solar power. The Solar Impulse 2 uses four 38.5 kW-hr NMC battery packs with 150 A-hr cells, totaling 154 kW-hr of energy storage. The batteries are made by […]
Rechargeable Coin Cell Batteries bring super-high power density
RJD Series batteries are different in design from other lithium-ion coin-cell batteries. A new encapsulation technology significantly increases storage capacity by completely utilizing the space within the cell case. High power density is a significant benefit in IoT wearable applications. Not only has the energy density per cell been improved, the failure rate is superior […]
Fuel cell power gains momentum
by Leland Teschler, Executive Editor Hydrogen fuel cells have numerous advantages over the best battery technology for running planes and even heavy duty vehicles. Batteries grab headlines these days, but it increasingly looks as though the power source likely to have the most impact on vehicle technology in the future will be the hydrogen fuel […]
Large electric vehicles responsible for as much
greenhouse gas as some conventional cars
At least for now, some electric vehicles (EVs) may generate about as much greenhouse gas (GHG) as some internal combustion engine vehicles (ICEVs) when judged over their entire cradle-to-grave life. So say researchers from Norway’s Industrial Ecology Programme and Dept. of Energy and Process Engineering, and the Norwegian University of Science and Technology. Writing in […]
