Researchers at Penn State have developed a fast charging technique to charge a battery in in electric vehicle in just ten minutes. By Nick Flaherty @ www.eenewspower.com The fast charging technique uses a self-heating battery design to provide faster charging at 60ºC, while cooling the rest of the system to make sure that the battery doesn’t […]

In one of our previous articles, we built a DIY air quality monitor which was based on measuring the amount of Hydrocarbon concentration in the air using the BME680 VOC Whisker. While things work quite well using that method, there are several other parameters and air constituents which also have the same devastating effect and may be present in the air,

Long battery-life and Low power consumption are usually top on the list of requirements for most hardware devices these days, as the weariness of having to constantly charge a device continues to have significant effect on customers’ choice. Asides from consumer applications, another reason fueling this demand is the growth in the deployment of IoT

The new battery is scheduled for mass production in September 2020, with potential applications primarily in automotive and industrial IoT devices. NGK INSULATORS, LTD. (hereinafter “NGK”) has successfully raised the maximum operating temperature of its coin-type “EnerCera Coin” (part of the “EnerCera®” series) battery up to 105 degrees Celsius. Sample shipments are currently underway, with mass
Lithium-ion batteries are flammable and the price of the raw material is increasing. Scientists and engineers have been trying to find out a safe yet efficient alternative to the Lithium-ion technology. The researchers of Empa and ETH Zürich have discovered promising approaches as to how we might produce powerful batteries out of waste graphite and

There are two things that you don’t want to do with any rechargeable battery on a routine basis: Overcharge it. Overdischarge it. While the above are true for lead-acid batteries, they are particularly true of Lithium-Ion chemistries, but for different reasons. With Lead-acid batteries: Lead-acid batteries – particularly the “flooded cell” types (e.g. those to

Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the battery. A suitable test current of approximately 250 mA gives you a more reasonable test. You can use a 6Ω resistive load at
Circuit provides constant-current load for testing batteries Continue Reading
Researchers at Cambridge University have just achieved a spectacular breakthrough in electronics design. They have developed new ultralow power transistors that could function for months or even years without a battery. These transistors look for energy from the environment around, thus reducing the amount of power used. Dr Sungsik Lee, one of the researchers at
