Main considerations for daily maintenance and maintenance of lithium batteries for electric vehicles

The lithium battery industry has developed rapidly in recent years, and its popularity has changed drastically compared with the previous 10 years. With the promulgation of the new national standard for the electric vehicle industry standard, it has also led the lithium battery for electric vehicles to a new direction. High density and good performance. Lightweight, it is more conducive to the extension of the cruising course. Compared with the lead-acid battery for electric vehicles of the same weight and size, the former has more than three times the cruising range of the latter. More and more people are equipped with electric vehicles. Lithium battery. So how should the lithium battery of electric vehicles be maintained? What should I pay attention to when using? The main points for attention in the daily maintenance and maintenance of lithium batteries for electric vehicles: (1) When the red undervoltage of the meter lights up, or the battery cell display has fallen below one third, it means that the battery has been removed from the state of lack of power, and this should be done in time Charge the battery. At this time, attention should be paid to avoid continuing to ride. Excessive use of the battery will cause great damage to the battery, and in severe cases, it may also cause the lithium battery to be scrapped. (2) In the process of riding an electric bicycle, you should avoid rapid acceleration. Slow acceleration is not only safe, but also avoids the large current changes of the lithium battery. Excessive current changes will accelerate line aging and shorten the life of vehicles and lithium batteries. And it may puncture some broken components and cause the lithium battery or the vehicle control circuit to malfunction. (3) When the electric vehicle is not used for a long time, the lithium battery should be charged to 30-50% when possible, and the connection between the battery and the electric vehicle should be disconnected. And check the battery power every 3 months, if over-discharge is found, replenish the power of the lithium battery of the electric vehicle in time. In addition, avoid storing the lithium battery fully. The fully charged lithium battery has high ion activity, and storage will passivate the battery and damage the battery. (4) When charging the lithium battery of an electric vehicle, it is necessary to avoid close to the fire source because it is carried out in an air-circulating and dry environment. (5) Lithium batteries for electric vehicles can generally be used in an environment of -20-60 degrees, but if the lithium battery needs to be charged, the ambient temperature must be above 0 degrees. (6) Do not short-circuit the positive and negative terminals of the lithium battery of electric vehicles to avoid danger. (7) Use the special charger provided by the manufacturer for charging. (8) Lithium batteries for electric vehicles are dedicated batteries, please do not use them for other purposes, otherwise it may cause damage to the battery or the corresponding equipment. (9) When there is a fire or explosion hazard, fire extinguishing equipment such as carbon tetrachloride should be used. (10) Do not disassemble the lithium battery of electric vehicles by yourself. (11) The battery is a consumable. When the lithium battery of an electric vehicle fails, it is not mandatory to use or charge the lithium battery of the electric vehicle. Abnormal lithium batteries are dangerous. (12) Avoid exposure of lithium batteries to sunlight. In daily use, we should pay attention to the power of the lithium battery of electric vehicles to avoid excessive discharge of electric vehicles. In terms of charging, the technology of lithium battery chargers is now very mature and automatically disconnects when the lithium battery is fully charged. Disconnect, this is very different from the old lead-acid battery. In order to make the lithium battery of electric vehicles more stable and have a longer life, please be sure to properly maintain the electric vehicles and lithium batteries under the manufacturer's instructions.
