In the absence of rapid advances in battery technology, making a fuss about charging technology is the only option. The startup company Qnovo is developing a way to provide mobile phone charging efficiency through a combination of hardware and software.
The fast charging technology developed by Qnovo will simultaneously improve the charging speed from both hardware and software aspects. When the battery power is lower, the charging speed is faster. So how fast is this fast charging technology?
For example, if you only have 20 minutes of charging time, the general charging method can only charge about 20%, and Qnovo's charging technology will allow your phone to reach 50% of the power (for different types of mobile phones and different size batteries will Differences). The following figure shows the test results of Qnovo:
Qnovo's technology uses a "group" approach to charging. It is different from the "constant-current and constant-voltage" method used in standard lithium-ion batteries. This charging method will slow down the charging rate until your battery is fully charged when your phone battery is charged.
Qnovo said that their charging technology is different from the standard lithium-iron battery using constant current and constant voltage charging. The traditional constant current and constant voltage charging method is to protect the battery and prolong the battery life. When the voltage is too low, the charging IC will be smaller first. The current goes to charge, when the voltage resumes, will begin to charge normally, Qnovo thinks this kind of fear that damages the charging way of the battery is the main reason that causes the charge to be too slow.
Let's take a look at Qnovo's method, which is to check the battery's response while charging to adjust the charging speed and repeat the process. The specific method is to first charge a small amount of electricity, pause for a moment to see how the battery reacts, and then recharge Into more battery power. If a normal 5V adapter can talk for 1.5 hours in 15 minutes, then the same charging time can be extended to more than 3 hours with Qnovo, and it can also delay battery aging.
Some people are worried that the battery will be damaged, Qnovo said to ensure the safety of charging, users can not just install their software, but also must be embedded in Qnovo's chip, so as to avoid damage to the battery.
At present, there are already many companies that want to cooperate with Qnovo, but Qnovo does not specifically disclose which vendors are there.
A salt lick is a deposit of mineral salts used by animals to supplement their nutrition, ensuring that they get enough minerals in their diets. A wide assortment of animals, primarily herbivores, use salt licks to get essential nutrients like calcium, magnesium, sodium, and zinc. When a saltlick appears, animals may travel to reach it, so the salt lick becomes a sort of rally point where lots of wildlife can be observed.
Farmers have historically provided salt licks for their cattle, horses, and other herbivores to encourage healthy Growth and development. Typically a salt lick in the form of a block is used in these circumstances, and the block may be mounted on a platform so that domesticated animals do not consume dirt from the ground along with the necessary salt. Salt blocks for farm animals can also be treated with medications, which may be convenient when someone needs to medicate shy animals, or a large group of animals.
