1. The internal switch element is used inside the lithium -ion battery. When the temperature of the battery rises, the resistance value rises, and the temperature stops discharge after the temperature is too high. 2. Set up a battery outlet in the structure. When the inner pressure of the battery rises to a certain extent, the pores are automatically opened to keep the internal pressure on the internal pressure imbalance of the alert and cause the battery to burst. 3. Optimize the electrolyte system. At prese

Many electric vehicle customers believe that the longer the charging time, the more battery battery. In fact, this is a misunderstanding. The charging time generally uses the charger to be extended to the green light within one hour as the best (take the Ao Koma electric vehicle as an example). Excessive time is likely to cause battery deformation, water loss and other phenomena. As a result, it is straightforward to harm the life of the battery, and even more serious problems such as short -circuit explosions will

How to connect lithium -ion battery packets and connect balanced charging 1. Diode isolation parallel charging balance method Take 6 single batteries as an example, disconnect the switch S1S5 and then connect the charging power. The diode is selected from 1N54015408, 3A rated current measured the positive pressure drop of the diode to 0.8V, and the current flowing over the diode when the forward voltage drops 0.7V is small. The maximum charging voltage of lithium iron phosphate has a maximum charging voltage

1 Application scenario of large -scale energy storage system New energy power stations, wind power or solar power stations, in order to achieve the purpose of flat -input power fluctuations, more and more power plants have begun to equip energy storage systems. Independent energy storage power stations have gradually entered people's vision with the reform of the power system, and independent energy storage power stations that live up to sell electricity have gradually appeared. Micro grids contain a s

The biggest difference between new energy vehicles and traditional cars is to use batteries as power -driven, so the technology of power lithium batteries is the core of new energy vehicles. What is the core technology of BMS? Recently, I saw a propaganda sign of a domestic company. Because of the underlying software such as the software architecture of AutoSAR, it claimed to fully master BMS software and hardware technology, reached the world's advanced level, and adopted multiple equilibrium control cap

Working principle and system composition working principle The principle of power generation of fuel power batteries is similar to the original battery or secondary battery. The hydroxide reactions and oxygen reduction reactions occur on both sides of the electrolyte septum. The electrons work through the external circuit and the reaction product is water (Figure 1). However, unlike the original battery, the reactant in the fuel power battery is not pre -stored inside the battery, but is discharged from the f

Hydrogen fuel power batteries are used in spacecraft and other high -tech applications. It is necessary to clean and efficient energy in these places. In your kitchen, about 10 minutes, you can make hydrogen fuel power batteries to experience how hydrogen and oxygen are combined and clean power. Do this fuel power battery, we want the following materials: Nickel -plated platinum silk, or pure platinum wire A popsicle stick, or a small piece of wood or plastic A 9V battery clip A 9V battery Some

The widespread use of lithium iron phosphate ion batteries, and the demand for battery capacity to continuously increase the demand for battery capacity, we need to connect multiple lithium -ion batteries in series, which leads to the increase in the total voltage of the battery. Therefore, the lithium -ion battery charging management chip is born. In order to alert lithium -ion batteries that affect the life of the battery in abnormal states such as over -charging, discharge, and over -current, the battery is usua

The advantage of lithium iron phosphate cells, the purpose of iron -lithium ion battery. The full name of lithium iron phosphate ion battery is lithium iron phosphate lithium ion battery. Because its performance is particularly suitable for power use, the word "power" is added to the name, namely lithium iron phosphate power lithium battery. Iron -lithium -ion battery capacity, high output voltage, good charging and discharge circulation performance, stable output voltage, and capable of large -current ch
