The Verge Chinese Station reported on October 5

What do you say about Google's new Chromecast Ultra? The new Chromecast Ultra looks like a small disc that can directly transfer streaming media files played by smartphones from the Internet to the TV. Simply put, Chromecast Ultra is just a new Chromecast, and there's not much difference.

Ultra in Chromecast Ultra said that it supports 4K and HDR at the same time, so the cost is also higher, reaching 69 US dollars (about 460 yuan), which is twice as many. However, there are very few content sources for the current 4K video. It is believed that as the content becomes more and more abundant in the future, the price may further decrease.

At the press conference, I did not have the opportunity to use Chromecast Ultra to play a video experience, but according to Google, Chromecast Ultra played 1.8 times faster than before and has better support for Wi-Fi networks.

Like previous generation Chromecasts, Chromecast Ultra still uses microUSB, not the latest USB-C interface. At the same time, the user can choose to directly power the TV or use the AC power supply. Chromecast Ultra is very smart and can use the Ethernet adapter to increase the bandwidth to handle 4K signals in the event of poor Wi-Fi signal.

However, in appearance, this “round and fat” Chromecast Ultra still does not seem to change much. (Author: Dieter Bohn compilation: Human)

Battery And Battery Packs

Battery is the energy source of AGV car, and also relates to the service life of AGV car.Common battery types for AGV vehicles include nickel-cadmium battery, nickel-metal hydride battery, lithium battery and lead-acid battery, which have the following characteristics:

1. Nickel Cadmium Battery

The nickel-cadmium battery used in AGV car has large internal resistance and can be used for large current discharge.

2. Nimh battery

It offers higher capacity at the same price as nickel-cadmium batteries, less pronounced memory effects, and lower environmental pollution.

3. Lithium battery

"Lithium battery" is a kind of battery with lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. Because lithium battery has the characteristics of high energy density, high voltage and stable operation, it is widely used.

4, lead acid battery

The electrodes are mainly made of lead and its oxides, and the electrolyte is a kind of battery with sulfuric acid solution.Lead-acid battery has the advantages of good invertibility, stable voltage characteristics, long service life, wide application range, abundant raw materials, renewable use and low cost.
