The saying goes: "Hot is three volts, cold in three nine. "Sanli Day is between the summer heat and the summer, the temperature is the highest in the year, and the days is hot. So what is the maintenance and operational skills of lithium-ion batteries in summer? 1.

How do you have a high temperature in summer? Power tools usually bring a set of "electronic control systems", which is equivalent to the brain of the power tool. Take the US Waiguqi power tool as an example, its electronic control system officially referred to as "USA Smart Red Union System". Its uses include, but are not limited to, monitoring the temperature of single-cell cells, controlling battery charging / discharging, supply overload protection, coordination machine and battery / charger .

* Discharge Overheal Battery Discharge When the battery temperature is too high, long When the time is overloaded, the system determines that the battery is overheating, and then cut off the charging and discharge protection switch of the circuit. The machine cannot be continuously used, and it needs to be allowed to cool; when the battery temperature falls back to the operating temperature range, the system is released, the battery and tools can be put into enter Normal use. * Restrictions on the charging of overheat cells, high temperature lithium-ion batteries, not only damage to the battery, shorten battery life, and even brings safety hazards.

The smart red couplet system is limited to the temperature of the US Waft Battery: When the battery temperature is at 5 ¡ã C -40 ¡ã C, the charger (automatic) starts working; the battery temperature does not surround this temperature, the charger red light flashes quickly. Waiting for charging. 2, control the quality of the temperature rise, the specifications of the battery cell, the structural design of the battery pack, the performance of electronic components .

These are the tight factors that determine the temperature rise speed, excellent "own conditions" cooperate with certain operational skills, Can better reduce battery heat. * After working for a while, let the machine empty operation, using the rotation of the fuselage rotor blade, drive the circulation of the machine's internal air, fast cooling for the machine * Regular cleaning machine into the exhaust, exhaust, dust cover, etc. Foreign body blocked, affecting heat dissipation * Reduce friction resistance to add or replace the appropriate amount of grease 3 for the machine mechanical transmission part, how to respond to the lithium ion battery accidental water? Summer precipitation is rich in the whole year, and the outdoor work weather is uncertain, and the processor should take into account this during design and processing, and it is still as an example of the US Wafi Ban.
