4.2v is the charging bound voltage of lithium-ion batteries, 3.7v is the discharge maintenance voltage. On mobile phones, when the battery is discharged to 3.6-3.7v, the phone will prompt that the battery is weak and needs to be charged and turned off. However, the discharge maintenance voltage of the battery maintenance board is only 2.75-3.0v.
The power consumption of household appliances in standby mode is very small, so the discharge current is also very small, and some do not have a heating phenomenon. However, when household appliances are working, according to the principle of parallel current circuits, the equivalent load resistance of their batteries is small, and they discharge with high current during operation.
When a battery discharges a portion of its electricity, its internal resistance increases. However, the current required for the operation of household appliances cannot be reduced. Therefore, a relatively large portion of energy is consumed on the internal resistance of the battery, causing it to heat up. At the same time, some batteries discharge faster, and the utilization time of the battery is quickly shortened.
Moderate heating of the battery for a long time can lead to an increase in the temperature of internal components, affecting the abnormal operation of the components;
Long term heating of the battery will increase its own heat. If it is sealed (such as se, which is not sealed and is directly installed into the battery), the battery will cause the internal air to expand violently, causing the battery to rise like an external object, and significantly causing the battery to expand;
Long term moderate heating of batteries can accelerate the aging process of the product itself and shorten its lifespan;
