Is the lithium-ion battery available for power tools? How to use and maintain the battery of cordless power tools?

What is the demand for lithium-ion batteries for power tools? How to use lithium-ion batteries for power tools. In recent years, with the continuous advancement of lithium battery technology and the gradual decrease in cost, the application of lithium-ion batteries in the field of power tools has increased. The cordlessness and portability of power tools have made lithium-ion batteries better in the field of power tools. The market has maintained a steady rise. The use of lithium-ion batteries in power tools has grown from 3 strings to 8-10 strings, and the number of applications has doubled. Therefore, there is a huge potential for the rise of the power tool lithium battery market in the future.

What is the demand for lithium-ion batteries for power tools?

Generally, lithium-ion batteries for power tools use 18650 cells or 21700 cells, which are connected in series and parallel with each control and protection circuit to form lithium-ion battery packs with different voltages and different capacities. Whether it is 18650 or 21700, you can find different manufacturers. According to different explanations, the common battery packs are 10.8V, 14.4V, 18V, and the capacity is relatively objective, which refers to the continuous discharge time with a certain intensity of current , Generally expressed in Ah or mAh.

At present, the power tool market is mainly divided into handheld tools, garden tools and other tools. The entire market requires power tools to ensure stability and safety, have greater power and torque, less noise, and have smart electronic tool telemetry. The technology of power tools is also gradually changing. Engines have higher torque and power, and are more efficient. Motor drive, longer battery life, compact and small size, fail-safe design, IoT telemetry, fail-safe design.

With the promotion of market demand and the support of some countries, the compound increase rate of the total installed capacity of global and Chinese power tools from 2011 to 2018 reached 44% and 41%, respectively, which exceeded the growth rate of power tool production. In 2018, the global power tool lithium The demand for ion batteries is 7.26GWh. It is estimated that the growth rate of installed capacity will fluctuate at around 10% in the next few years, and it will stabilize by 2025.

Although the level of lithium-ionization of power tools in my country has continued to improve in the past five years, it has only reached 23% by the end of 2019. Compared with the total scale of 260 million power tools, there is still a lot of room for substitution. With the accelerated popularization of lithium batteries for power tools, the expansion and investment of lithium-ion batteries for power tools will become more frequent in the future. It is predicted that in 2023, the domestic power tool lithium-ionization rate will rise from 23% in 2019 to 55%, and the output will reach 151 million units, which will give rise to the demand for lithium-ion batteries to reach 7.5GWh.

How to use lithium-ion batteries for power tools
① Regularly clean the air inlet, outlet, dust cover, etc. of the machine to prevent dust and foreign objects from clogging and affecting heat dissipation;
②It is necessary to use the charger specified by the manufacturer to charge the battery. A charger suitable for a certain type of battery may cause a fire when charging another type of battery;
③After working for a period of time with the lithium ion battery of the power tool, let the machine run without load for a while, use the rotation of the rotor blades of the fuselage to drive the air circulation inside the machine, and quickly cool the machine;
④If improper use of power tools lithium batteries may cause liquids to flow out, please prevent these liquids. In case of contact, rinse immediately with water, and seek medical attention if the liquid enters your eyes. The escaping liquid may cause skin irritation or cause burning.

Regarding the lithium-ion batteries used in power tools, there are still some misunderstandings in the market. You may think that the power lithium battery technology for automobiles is a higher, precise and cutting-edge technology. In fact, the lithium-ion batteries used in power tools must meet the requirements of extreme high and low temperature. Use in the environment, and must adapt to strong vibration, fast charge and release, and the protection design is relatively simple, these requirements are not lower than the power lithium battery for vehicles, so it is actually very challenging to make high-performance, high-rate batteries. of.

Although lithium-ion batteries have broad prospects in the power tool market, they are superior to power lithium batteries in terms of price, profit, and remittance speed, but the international power tool giants are very picky about the choice of lithium-ion battery companies, not only in terms of output. With a certain scale, it must have mature production technology in terms of R&D and technical strength. Therefore, for companies that want to transform into the power tool lithium-ion battery market, it is difficult to enter the supply chain system of the international power tool giants without technical reserves.

With the development trend of miniaturization and convenience of electric tools, lithium-ion batteries are more and more widely used in electric tools. In general, before 2025, the application of lithium-ion batteries in power tools will rise rapidly. Whoever can occupy this market segment first will be able to survive the accelerated reshuffle of power lithium battery companies.
