Lithium battery charging temperature range

Hello everyone, I am the intelligent customer service representative of Time Fortune Network, I will answer the above questions for you. The charging voltage range of 12V lithium battery is 12.6V for 3 cells and 16.8V for 4 cells. Lithium batteries usually have protective plates, so the charging voltages are also different. For a single load (without protective plates), each cell is 3:7 V, or 4.2 V when connected in series, the voltage is superimposed by analogy.

Lithium batteries are batteries that use lithium metal or lithium alloy as the anode material and use a non-aqueous electrolyte solution. The difference between lithium batteries and lithium-ion batteries is that the former is a primary battery and the latter is a rechargeable battery. Since the chemical properties of lithium metal are trActive, processing, storage and use of lithium metal have very high environmental requirements, so lithium batteries have not been used for a long time. With the development of microelectronic technology in the late 20th century, the number of miniaturized devices has increased day by day, placing high demands on power supplies. Lithium batteries then entered a phase of large-scale practical use. Since Apple launched smartphones, then tablets, in 2007, the world has entered the era of intelligence. The strong demand for smartphones and tablets has rapidly promoted the sales of digital lithium batteries, among which mobile phone lithium batteries account for the largest sales volume.

Is it normal for the ternary lithium battery to be charged at 50 degrees?

It will be damaged

These typeses of charging lithium batteries Very harmful method for the battery

Type 1: Using the charger indiscriminately

When When charging lithium batteries, it should be limited to charging limiting current and voltage, otherwise overcurrent and overheating will occur, which will not only damage the battery, but also pose certain safety risks.

To put it simply, don't mix chargers. For example, if an electric car has a voltage of 60V, then when using a charger, do not use one 48V and one 48V. a 72V charger. Use as many chargers as possible. 60V voltage charger and try to choose the original charger that came with the original car. This will help protect the battery and prevent "lithium dendrites" from forming in the battery due to overcharging.

Type 2: Less than zero load

The optimal charging and using temperature of lithium batteries is 25℃, the lower the temperature will affect the charging and discharging of the battery. Many car owners know that when the temperature is low, the storage capacity of the battery deteriorates, affecting its service life, and it is easy to overcharge and damage the battery.

Although the life of lithium batteries at low temperatures is not as serious as that of lead-acid batteries, if the lithium batteries are charged in a lower environment to zero, the damage caused is not only to the battery, but also to the battery life. Not satisfied with the fact that it is so simple, it will worsen the formation of "lithium dendrites" and cause irreversible damage to the battery. Therefore, many lithium battery engineers point out. that this methode loading should be avoided.

Lithium battery operating temperature

Ternary lithium battery charging temperature50 degrees is normal. Conventional lithium-ion battery operating temperature: -20°C~60°C, but generally when the temperature is below 0°C, the performance of the lithium-ion battery will decrease and the discharge capacity will decrease accordingly. The operating temperature of lithium-ion battery at full performance is generally 0-40°C. The temperatures of lithium-ion batteries required by particular environments vary, and some can even operate normally in environments hundreds of degrees Celsius.

First of all, the optimal operating temperature of lithium batteries is between 20℃ and 25℃. In this temperature range, lithium batteries perform best, and the capacity and life ofbattery life can be maximized. When the temperature exceeds 25°C, the battery capacity decreases and the chemical reaction inside the battery accelerates, reducing its lifespan. When the temperature is lower than 20°C, the battery output power will decrease, and the diffusion rate of battery active materials will also slow down, affecting the battery performance.

In addition, I would also like to remind you that under extreme temperature conditions, such as high temperature (over 60°C) or low temperature (less than -20°C), the Performance and safety of lithium batteries will be seriously affected. In a high temperature environment, the electrolyte will become unstable, which may cause dangerous situations such as overheating and battery explosion; in a low temperature environment, the reaction speed of the battery will be greatly reduced,which can lead to a sharp decrease in battery capacity. Therefore, try to avoid using lithium batteries in extreme temperatures to avoid safety risks.

I hope the information above is helpful to you! If you have any further questions, please continue to ask.
