What is the impact of fast charging on lithium batteries
814 2023-12-20
Theoretical evidence shows that fast charging is the most destructive for lithium-ion batteries. The fast charging function is harmful to the phone battery. In fact, both fast and slow charging can damage the battery life. The main reason why fast charging affects the lifespan of mobile phone batteries is that it increases power. Charging brings more heat than slow charging, and high temperatures accelerate battery aging.
Fast charging lithium-ion batteries refer to batteries that have been charged in a short period of time, usually fully charged within 6 minutes, with a capacity of over 95% of the rated capacity. Time is life, and fast charging batteries shorten charging time, improve efficiency, and reach international advanced levels.
Requirements for fast charging lithium-ion batteries:
According to the structural characteristics of fast charging lithium-ion batteries, the maximum charging termination voltage should be 4.2V, and overcharging is not allowed. Otherwise, the battery may be scrapped due to the removal of too much lithium ions from the positive electrode.
Lithium ion batteries require high charging and discharging requirements, and can be charged using dedicated constant current and constant voltage chargers. Usually, constant current charging is switched to constant voltage charging after reaching 4.2V/kWh. When the constant voltage charging current drops to within 100mA, charging should be stopped.
Charging current (mA)=0.1~1.5 times the battery capacity (such as a 2000mAh battery, its charging current can be controlled between 200~4000mA). The conventional charging current can be selected at around 0.5 times the battery capacity, and the charging time is about 2-3 hours.
What is the impact of fast charging on lithium-ion batteries
Whether lithium-ion batteries can be charged quickly depends on the experimental data of lithium-ion battery manufacturers. Not all lithium-ion batteries can be charged quickly, otherwise it will greatly reduce the lifespan of lithium-ion batteries, and there is also a risk of fire, explosion, and other hazards. Therefore, various manufacturers will configure slow and fast charging ports based on the characteristics of lithium-ion batteries, and the charging process will be managed uniformly by the BMS system. As long as charging according to the manufacturer‘s requirements is safe.
Lithium ion batteries and lead batteries are a principle. The working principle of fast charging is to first add voltage, and then add the current current. Just like this, fast charging also uses this principle, so a large amount of current storage boards will experience overspeed reactions. This reaction generates a large amount of heat, which can damage or prematurely age the battery due to internal resistance and exceeding the limit temperature value.
