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...

The disconnection detection function is described above. This time, the equalization function is also one of the main functions of BMS.The concept of cell balance is believed to be familiar to everyone. The main reason is that the current cell consistency is not good enough. It needs to be improved...

After the introduction of AC charging, we will continue to introduce the DC charging interface today. Compared with AC charging, DC charging is more pure. There is only one charging mode and one connection mode without so many categories.The definition of vehicle DC charging interface is shown in th...

The Argonne National Laboratory of the United States Department of Energy announced three days ago that scientists have developed a new cathode coating using oxidation chemical vapor deposition technology, which can help solve several potential problems of lithium-ion batteries.The new cathode coati...

Lithium-ion battery has inherent advantages in the application of the Internet of Things. Its high voltage platform, large capacity and long storage life are widely used in various industries of the Internet of Things. Low-current application scenarios usually use lithium sub-energy batteries, while...

The 18650 lithium-ion battery is one of the most common lithium-ion batteries on the market at present. What are the key points about the PACK process of the 18650 lithium-ion battery? Let's take a look.The 18650 lithium battery pack process is mainly formulated according to the structure of the...

TWAICE, a Munich based start-up, is developing "predictive analysis" software for battery management of electric vehicles and other devices.An analysis software will be used to analyze the "health condition" of the battery to extend the battery lifeThis round of financing was led...
