Lithium Batteries in Power Tools

Power tools are various general-purpose construction tools that rely on electric power to drive, and generally rely on hand-held operation by workers. They are widely used in construction and decoration, light industry manufacturing and other fields. Compared with purely human hand tools, power tools use electricity to greatly increase the torque, speed, impact and so on of the tools, greatly improving work efficiency. There are many types of electrical tools. The most used types are electric drills, angle grinders, electric wrenches, electric saws and sanding machines. In a broad sense, garden tools, including weeding machines, are also a large category of power tools.

Lithium batteries are an important component of power tools. Compared with the previous nickel-cadmium nickel-metal hydride batteries, lithium batteries can well meet the market trend of miniaturization, lightweight and high efficiency of power tools due to their environmental friendliness, lighter weight, greater capacity, efficiency and better cycle life. Therefore, lithium battery tools occupy the dominant position in the cordless power tool market. However, due to the particularity of lithium batteries, the safety of charging and discharging, as well as the consistency between individual batteries, must be considered in practical applications to prevent the deterioration of battery characteristics. Therefore, the whole machine system of power tools is required to monitor and reliably protect the battery pack to ensure that the whole machine can be used safely.

Certain norms must be followed during the use of power tools. This is not only related to the maintenance of power tools, but also to the personal safety of users. Therefore, when using power tools, we must pay more attention to the workplace, electric safety, personal safety, and power tool maintenance and maintenance. The following are the precautions for the use of power tools and maintenance issues.

1. Workplace
  · Please keep the work area clean and well lit. Chaotic and dim work areas may cause accidents.
  · Please do not use power tools in environments where there is a risk of explosion, such as environments with combustible liquids, gases or dust. Sparks from power tools may ignite dust and gas.

2. Electric safety
  · The power socket must match the power plug of the power tool. Under no circumstances can the power plug be modified.
  · Please avoid physical contact with grounded surfaces, such as pipes, heating, stoves, and refrigerators. If your body is grounded, it will increase the risk of electric shock.
  · Keep the equipment away from rain and humid environments. Water entering the water of power tools will increase the risk of electric shock.
  · Please do not move the power cord for other purposes, such as when lifting, suspending tools, or pulling the plug out of the socket. Keep the power cord away from heat sources, oil stains, sharp edges, or tool parts in motion. Damaged or entangled power cords can increase the risk of electric shock.
  · When you use power tools outdoors, please use an extended power cord that is allowed to be used outdoors. The use of an extended power cord suitable for outdoor use can reduce the risk of electric shock.

3. Personal safety
  · Please stay awake, focus on work, and operate power tools rationally.
Please do not use power tools when you are tired or under the influence of drugs, alcohol, or drugs. The instantaneous distraction of attention when using power tools can cause serious injury.
  · Please wear personal protective equipment and always wear a protective eye mask.
According to the form and characteristics of power tools, bring personal protective equipment, such as dust masks, non-slip safety shoes, safety caps or noise protection earmuffs, which can reduce the risk of injury.
  · Please avoid turning on the device unintentionally.
Before inserting the plug into the socket, make sure that the switch is set in the “off” position. When moving or handling power tools, if you put your finger on the switch, or when the switch is in the open position, plug the power tool into the power supply, it may cause an accident.
  · Please remove and remove the adjusting screwdriver or wrench before turning on the power tool.
Tools or wrenches that come into contact with rotating equipment parts may cause life-threatening injuries.
  · Please don't overestimate yourself.
Please always take care to stand safely and maintain your balance. This ensures that you can better control the power tools in the event of an accident.
  · Please wear appropriate clothes.
Don't wear clothes and accessories that are too wide. Please keep your hair, clothes, and gloves away from working parts. Sagging clothes, accessories or long hair may be involved in moving parts.
  · Correct connection
If the purchased equipment includes a vacuum or dust collection system, please connect and use these equipment correctly. The use of these equipment can reduce the danger caused by dust.
