26650 battery

26650 battery refers to a battery with a single cell capacity of 26650 mAh and a voltage of 4.2V, which can be connected in series and parallel to form multiple small-capacity battery systems; lithium iron phosphate battery refers to a small cell with a single cell capacity of lithium iron phosphate batteries connected in series. capacity battery. Lithium iron phosphate charge over-discharge protection device:

1. The lithium iron phosphate battery charging protection device is suitable for all lithium-ion rechargeable batteries, including 26650, lithium iron phosphate and other non-memory lithium iron phosphate lithium-ion batteries.

Using advanced microprocessor technology, the rechargeable battery can be quickly and accurately automatically overcharged and overdischarged to ensure safe and efficient charging of the rechargeable battery. 2. The built-in current protection and short-circuit protection functions can ensure that the battery cells will not be short-circuited due to excessive current during charging, and protect the cells from being damaged, thereby prolonging the battery life. 3. Support a variety of output voltages: it can be connected to a DC power supply to supply power to other electronic devices; 4. Provide two discharge modes of overvoltage and overcurrent; 5. Provide 5V/9V/12V/24V output, suitable for charging different types of lithium batteries .

2. The device uses an ASIC to control the charging process, which can ensure battery safety during the entire charging process.

When this device is charging a lithium battery, the charging current depends on the specific conditions of the lithium battery. At the same time, when the current is too high, it will automatically cut off the power supply and give an alarm. Lithium iron phosphate battery is made of LiFePO4 (4% phosphorus content) or lithium iron phosphate (30% iron content), which has the advantages of light weight, small size, high energy density, good safety and low price. Lithium iron phosphate batteries are favored for their environmental protection and safety. Lithium iron phosphate long-life energy storage batteries can be used in wind power generation, electric vehicle power battery packs and smart grid systems and other fields.

3. This device can be used in conjunction with other various types of protective devices

(1) Battery over-discharge protection device: This device is mainly used to collect voltage and current signals during the charging process of various batteries, and compare and analyze the data of each channel to judge and prevent battery over-discharge and protect the battery pack. (2) Battery overcharge protection device: This device can detect and judge the overcharge condition of 26650/26622 batteries;

4. It can communicate with the computer through the serial port (it can realize the communication with the computer monitoring system)

A password can be set. When the user needs, the lithium battery can be programmed through the computer to realize the functions of charge and discharge control, data storage and so on. Lithium iron phosphate battery has the characteristics of high safety, long life, high current charging and long-time discharging without explosion. It is a new type of high-safety battery product and has been widely used abroad.

5. Adopt advanced industrial control computer for data collection and processing.

The design principle of the device is mainly to analyze various faults encountered by users in practical applications, so as to carry out corresponding control. The design scheme and schematic diagram of the charging protection device are shown in the table below: The charging protection device has functions such as lithium battery charge and discharge protection, voltage undervoltage protection, temperature undervoltage alarm, and current undervoltage and overdischarge alarm. Through system control, the system can work normally, and in case of abnormality, it can alarm or send fault information to relevant personnel in time. The charging protector adopts advanced microcomputer control technology, with data acquisition frequency can be customized according to needs), data processing (sampling frequency can be customized according to customer needs), result display (through LED digital display, and manual input and output data can also be queried), Functions such as data storage and report printing.
