The hazards of fast charging on car batteries

How much do you know about the hazards of fast charging to car batteries? The vehicle energy supplement of fast charging methods must be able to solve the above problems at present, the charging time of the vehicle, reducing anxiety and anxiety in the life journey, charging fast charging, long-term use of fast charging electric Car charging piles will reduce battery life. Of course, in electric vehicles, the principle of fast charging is to store direct current (dc) directly in the battery. Generally, a single charge is used. The output voltage basically reaches a voltage of about 300 to 400v, and some even reaches 50 to 100 kilowatts. Voltage. Long-term fast charging of the battery will cause the battery to overheat, and the battery will decay very quickly under long-term high temperature. In fact, in simple terms, in addition to these, the impact of fast-charging lithium batteries on vehicles also includes special battery cycle life values, because the battery itself is through electrochemical reactions and electrical equipment, and poor charging chemical reactions occur, and at the same time, the battery will be charged instantly. Input in a larger current, the repeated use of fast charging will reduce the recovery of the battery and reduce the charge and discharge cycle of the battery. Fast charging is very high for the quality of the battery. The high current and battery reaction conditions are too harsh and severe. If you are far from the equilibrium state, there will be greater loss of battery life, and the safety factor will be greatly reduced, so don't make it as small as possible. Secondly, in terms of the internal structure of the battery, the impact of the battery is also relatively large. First, fast charging will react with the electrode data and electrolyte inside the battery. Other side reaction temperatures will be accompanied by some, such as the decomposition of the electrolyte and the deposition on the electrode. To a certain extent, the battery capacity will gradually decrease. Although in theory fast charging is harmful to the battery, in order to reduce the damage to the battery, the charging pile , Bring some DC charging piles with active protection function. The BMS system in the car will protect the power lithium-ion battery and prevent overheating. If the fast charging pile is used to charge the electric vehicle for a long time, it will reduce the battery life to a certain extent.
