About the interpretation of lithium battery charger design scheme

Source: 2020 - 03 - 25 clicks loathsome: lithium ion battery has high energy weight ratio and volume ratio, no memory effect, can be repeated charging, long service life, are cheaper. Lithium battery widely used in bypass machine model, fixed wing and helicopters, stable discharge, wide working temperature; Allow larger charging current, charging speed, low self-discharge, long storage life; Has the advantages of high energy, energy storage density. The following is 11. 1 v li-ion battery charger design scheme. 11. 1 v lithium battery widely used in the bypass machine model, fixed wing and helicopters, stable discharge, wide working temperature; Allowing large current charging, charging speed, only 1 ~ 2 hours full of; No memory effect; Low self-discharge rate, long storage life; High energy, energy storage; High output voltage ( A single additional voltage is commonly 3 of lithium battery. 6 v, and a single nimh batteries and nickel-cadmium battery voltage is only 1. 2V) Wait for an advantage. When lithium batteries to prevent excessive charging, if the voltage is above voltage charging or charging current is greater than the rated current, will damage the lithium battery, may make the scrap. In the case of charging excessive, excess energy lithium battery temperature, electrolyte can decompose to produce gas, make the internal pressure increases, the risk of spontaneous combustion or broken. When using lithium batteries and to prevent excessive discharge, excessive discharge will leads to the deterioration of the battery characteristics and durability, charging less often.
