Lithium battery industry has developed rapidly in recent years, the popularity of the last decade than a sea change, with the promulgation of the new national standards for electric vehicle industry standards, thus also guiding the lithium battery for electric vehicles to a new direction, lithium battery energy density is high, good performance. Light weight, more favorable cruise course extension, the same weight and volume of electric vehicles with lithium batteries and lead-acid batteries compared to the former range is already more than three times the latter, more and more people equipped with lithium batteries for electric vehicles. So how to maintain the lithium battery for electric vehicles? What do you need to pay attention to when using them?
Electric car lithium battery daily maintenance and maintenance of the main attention matters.
(1) When the red undervoltage of the meter lights up, or the battery cell display has been lower than one-third, indicating that the battery has been in addition to the state of lack of power, this should be timely to charge the battery. At this time should pay attention to avoid continuing to ride, excessive use of the battery will cause great damage to the battery, and in serious cases may also lead to lithium battery scrap.
(2) electric car riding process, should avoid rapid acceleration, slow acceleration is not only safe, but also to avoid the lithium battery how much current change. Excessive current changes will accelerate the line aging, shortening the life of the vehicle and lithium batteries. And may break down some breakdown components lead to lithium battery or vehicle control circuit failure.
(3) When the electric vehicle is not used for a long time, the lithium battery should be charged to 30-50% power when possible, and disconnect the battery from the electric vehicle. And every 3 months to check the battery power, such as the discovery of over-discharge, timely replenishment of the electric vehicle lithium battery power. Also need to avoid storing the lithium battery full. After full of lithium battery electric ion activity is high, storage will make the battery passivation damage battery.
(4) electric car lithium battery charging, because in the air circulation dry environment, need to avoid close to the source of fire.
(5) Electric car lithium battery can generally be used in -20 - 60 degrees, but if you need to charge the lithium battery, you need to be in the ambient temperature of 0 degrees or more.
(6) Do not short-circuit the positive and negative ends of the electric car lithium battery to avoid danger.
(7) Use the special charger provided by the manufacturer for charging.
(8)The electric car lithium battery is a special battery, please do not use it for other purposes, otherwise it may lead to damage to the battery or the corresponding equipment.
(9) The fire or explosion hazard should use carbon tetrachloride and other fire extinguishing equipment.
(10) Please do not disassemble the lithium battery of the electric vehicle by yourself.
(11) The battery is a consumable, when the electric car lithium battery failure, do not force to use or charge the electric car lithium battery operation. The abnormal lithium battery has certain danger.
(12) Lithium battery should be avoided to be exposed to the sun.
Daily use, we should all pay attention to the electric car lithium battery power, to avoid causing the electric car over-discharge, charging, the lithium battery charger technology is now very mature, full of automatic disconnection, so when the lithium battery is full can be disconnected, this and the old lead-acid batteries are very different. In order to make the electric car lithium battery more stable and longer life, please be sure to carry out the correct maintenance of the electric car and lithium battery in the manufacturer's guidance.
