With so many batteries, from cell phones to EVs, that are dependent on lithium, an alternative is always welcome. Solid-state chemistries could significantly reduce the risk of overheating and fire. We’ve become dependent on lithium-ion (Li-ion) batteries to power cell phones, EVs, and everything in between. Today’s Li-ion batteries can produce low and high voltages.…
Research shows improvements for fast-charging of Li-ion batteries
Researchers at Chung-Ang University used high-concentration electrolytes to improve safety and prevent cell swelling caused by lithium plating. To achieve a greater adaption of electric vehicles, the automotive industry needs fast-charging batteries that don’t compromise energy density. Lithium plating for ultra-fast charging raises safety concerns due to high cell polarization, requiring careful attention. During fast…
Trigger alerts when Li-ion batteries get too hot
TTape from Littelfuse, set of temperature-triggered switches, raises a bit that indicate hot batteries. Li-ion batteries can get hot, which can cause failures or worse in the products they power. Thus, it’s important to monitor their temperature and act before damage occurs. You can monitor temperature with a set of thermocouples, scan them, and write…
EV battery tests involve lots of power
In a video, EE World spoke with a power-supply applications engineer about why RV batteries use such high voltages and how to test them. Batteries are perhaps the most expensive component of an electric vehicle. Typically producing 800 V to 900 V, batteries deliver the power needed move the vehicle. Of course, EV batteries need…
Low-power TCXO improves IoT battery life
The SiT5008 from SiTime goes to 60 MHz, draws 3.5 mA, and features a standby mode.
