Selection of chargers for 18650 lithium batteries.
18650 lithium batteries are generally divided into two types: energy type and rate type. Energy type batteries are mainly characterized by large capacity, but the discharge current is relatively small; The rate type can discharge high current and has a lower capacity; Energy batteries are used in industries such as transportation, intelligent robots, and energy storage, while rate batteries are used in industries such as electric tools and garden tools.
The specific applications of energy batteries are as follows:
1. Transportation field: Widely used in the transportation field, such as common electric bicycles, electric two wheelers, balance bikes, etc. Currently, the main market is overseas. As a transportation tool, more attention is paid to the battery cell's endurance, fast charging ability, charging temperature, and discharging temperature range. The matching battery cell models on the market include 18650-26V, 18650-29V, 18650-33V, 18650-35V, etc.
2. Intelligent robots: widely used in the field of intelligent robots, such as common automatic guided transport vehicles, food delivery robots, navigation robots, etc. The main market is in the catering industry and express transportation in major shopping malls. The battery life, float charging ability, and cycle life of the battery cells are also valued, and the matching battery cell models are 18650-26V, 18650-29V, 18650-33V, 18650-35V, etc.
3. Energy storage field: widely used in the field of energy storage, such as common portable energy storage such as outdoor power supply, home energy storage, communication energy storage, etc. Currently, the conventional charging current of battery cells on the market is between 0.2~0.5C, fast charging can even reach 1C, and discharge current is between 0.2~1C. Matching battery cell models on the market include 18650-26V, 18650-29V, 18650-33V, 18650-35V, 21700-50E, etc.
The specific applications of rate type batteries are as follows:
1. Electric tools: widely used in electric drills, angle grinders, electric wrenches, electric saws, sanding machines, etc., mainly focusing on the electrical performance of the battery cells, including their high rate discharge and fast charging capabilities; At the same time, more attention is paid to its reliability, such as high-frequency vibration, high safety, and wide temperature range. Currently, there are matching solutions for battery cells in the market, including 18650-15P, 18650-20P, 18650-25P, 21700-40P, etc.
2. Garden tools: widely used in electric drills, angle grinders, electric wrenches, electric saws, and sanding machines.
