NiMH cells and finished battery packs offer two important features in conjunction with each other: Good performance at low temperatures and long life at high temperatures. Panasonic, one of the world’s leading battery manufacturing companies, a variety of NiMH cells with wide temperature ranges. These cells provide new electrode development which allow for a wide […]
Range of rechargeable Li-ion batteries powers up wearables and hearables
The task of opening or starting a modern car is now the task of miniature computers, which are designed by car manufacturers to perform an increasing number of functions. These smart keys can do quite a lot more. For example, they provide information about the oil level, the distance that can still be traveled, the […]
Charging electric vehicles, Part 1: The numbers
It’s nice to envision that recharging an electric vehicle is as straightforward as filling up an internal combustion vehicle, but it’s not: there are multiple charging, power, and connector options as well as limitations. You’re driving your internal-combustion (IC) car, and the gauge indicates it’s time to get “gas” (of course, it’s actually gasoline). So […]
New from the research lab: High-energy textile lithium battery
Researchers at The Hong Kong Polytechnic University (PolyU) say they have developed a highly flexible, high-energy lithium battery for wearable electronics with a myriad of applications. PolyU’s novel lightweight Textile Lithium Battery demonstrates an energy density of more than 450 Wh/L and flexibility — with a bending radius of less than 1 mm and foldability […]
Battery self-discharge and designing for long life
Battery chemistries each have special qualities that can make certain cells impractical for varying kinds of internet-of-things applications. Sol Jacobs | Tadiran Batteries Circuit designers often find themselves in the position of trying to squeeze as much life as possible out of a battery. Today there is much discussion about boosting battery life through use […]
Extended operating range battery chargers optimized for wheelchairs
Phihong has announced its lineup of extended operating range battery chargers for power wheelchairs and mobility scooters. The complete line of products includes 2.5A, 3.5A and 8A chargers for different battery capacities. The DA80U-240A-R and the DA64U-240A-R, rated 24V/3.5A and 24V/2.5A, respectively, work with AGM batteries and come in a compact, fan-less case measuring 6.14” […]
Small lithium-ion rechargeable batteries feature high discharge/charge rates
Nichicon Corp. has developed the new Small Lithium-Ion Rechargeable Battery (SLB series) in conjunction with Toshiba Infrastructure Systems & Solutions Corp. SCiB technologies. Features The main feature of the SLB series includes: 1) A high rate of charge/discharge. The batteries are able to charge to approximately 80% in three minutes and discharge to 95% of […]
Maximizing efficiency and safety with rechargeable batteries
Some rechargeable lithium battery chemistries need more TLC than others when it comes to safety precautions. TOM BLAHA, MEMORY PROTECTION DEVICES RECHARGEABLE BATTERY TECHNOLOGY has come a long way, continually boosting performance with fewer annoying memory effects that severely limited the useful operating life of earlier generation cells. The most common rechargeable battery chemistries commercially […]
How long can a battery really last?
It pays to know how a testing regime can reveal whether specific types of lithium batteries will last as long as an application demands. SOL JACOBS, TADIRAN BATTERIES DESIGNERS MUST UNDERSTAND how their end device will consume power before they can choose a battery. Will the battery be depleted in a matter of hours, as […]
Pin-type rechargeable lithium battery targets tiny applications
