Recently, researchers from Tianjin University ranked some of the most commonly used battery chemicals according to the parameters required for power grid energy storage.In batteries, different chemical components have different advantages and disadvantages, which makes them more or less suitable for...

After 2012, one kind of material began to receive attention, that is MXene material. This is a kind of metal carbide and metal nitride material with two-dimensional layered structure, and its shape is similar to the potato chips with overlapping chips. This material can be widely used in the fields...

In recent years, with the development of electronic technology, 5G technology and artificial intelligence, global electronic products tend to develop in the direction of intelligence, thinness, wireless interconnection, entertainment, etc. Products represented by TWS (true wireless Bluetooth) earpho...

With the rapid development of the Internet of Things smart city and other markets, a large number of industries have begun to use primary lithium batteries as power solutions for terminal equipment. At the same time, everyone will have questions about whether the battery capacity is sufficient. Xiao...

AFE (analog front end), which is an analog front end in Chinese, refers specifically to the battery sampling chip in BMS, which is used to collect cell voltage and temperature.Before writing this, I thought about it for a long time. There are too many places to write about AFE. A small place can be...

The previous AFE started and wrote another article with the heat.The most important reason we use the sampling chip is its high accuracy, but we should also use it carefully, because every link on the whole sampling circuit may cause sampling accuracy deviation, such as the resistance on the samplin...

The NTC in temperature sampling was introduced earlier. In fact, there is nothing about the design of temperature sampling circuit. I am ready to write it again; In the second part, I want to change the topic, otherwise it will be boring. I want to introduce the whole picture of BMS, first the whole...

The temperature sampling circuit of the cell is almost the same. The external NTC resistance is measured by ADC, and the resistance value is converted into the temperature value, so as to obtain an analog quantity close to the real temperature of the cell. In fact, many people think that BMS hardwar...

This time, change another topic, less rational, more emotional, or it's really boring and can't be written down.Sometimes when I brag or listen to others, I often hear the word IP67, which gives me a very strong feeling. But I don't know what IP67 is anymore. So take this opportunity to...
