LITHIUM-ION BATTERY
Advantage
1. Advantages of lithium battery compared with lead-acid battery.
(1) Lithium batteries have many inherent advantages that lead-acid batteries do not have, such as small size and light weight, because lithium batteries are portable and have high capacity density. With the same weight and volume, the installed energy is many times that of lead-acid batteries.
(2) Strong power, longer mileage, the same car, same configuration, the performance of the car when installing lithium battery is significantly improved compared with that of the car when installing lead-acid battery, such as acceleration performance, climbing performance are obviously better than lead-acid battery.
(3) The battery is recycled more times and has a longer service life, which is also a key point emphasized in the new national standard for batteries. Generally, the cycle times of ternary lithium batteries are about 1000 times. According to the general usage of our current electric vehicles, lithium batteries can be used for at least 4 years, and the most important thing is that they can be recycled, which will maximize energy utilization!
2. Safety characteristics of lithium-ion batteries.
(1) Short circuit: no fire, no explosion.
(2) Overcharge: no fire, no explosion.
(3) Hot box test: no fire, no explosion (constant temperature of 150℃ for 10min).
(4) Acupuncture: no explosion (use a Ф3mm nail to penetrate the battery).
(5) Plate impact: no fire, no explosion (10kg heavy object hits the battery from a height of 1M).
(6) Incineration: no explosion (gas flame grill battery).
3. Multiple protection mechanisms for lithium batteries.
(1) Automatic shut-off protection of diaphragm at 135℃.
Adopt international advanced Celgard2300PE-PP-PE three-layer composite membrane. When the temperature of the battery reaches 120℃, PE membrane pores on both sides of the composite membrane are closed, the internal resistance of the battery increases, and the internal temperature of the battery slows down. When the temperature of the battery reaches 135℃, PP membrane pores are closed, the internal circuit of the battery is broken, and the battery is no longer heated, thus ensuring the safety and reliability of the battery.
(2) Adding additives into the electro-hydraulic system
When the battery is overcharged and the battery voltage is higher than 4.2v, the electro-hydraulic additive polymerizes with other substances in the electro-hydraulic, which greatly increases the internal resistance of the battery, forms a large open circuit inside the battery, and the battery no longer warms up.
(3) Composite structure of battery cover.
The battery cover adopts a notch explosion-proof structure. When the battery is heated up, part of the gas generated during the internal activation of the battery expands, and the internal pressure of the battery increases, and the pressure reaches a certain degree, and the notch cracks and deflates.
(4) Various environmental abuse tests.
Carry out various abuse tests, such as external short circuit, overcharge, acupuncture, flat impact, incineration, etc., to investigate the safety performance of the battery. At the same time, temperature shock test and vibration, drop, impact and other mechanical properties tests were carried out to investigate the performance of the battery in the actual use environment.
Maintenance precautions
1. Prevent excessive discharge and charging.
Over-discharge and over-charge are actually things that many users will encounter. For example, sometimes they may forget to charge and sometimes forget to unplug the power supply, resulting in long charging time or long service time, which will cause certain damage to the battery of electric vehicles. Over-charging will cause the active substances in the battery plate to fall off, which will shorten the life of the battery. At the same time, over-charging may cause the electrolyte to dry up and the heat to run out of control, which will eventually lead to the deformation of the battery shell.
2. Prevent overcharge
If the battery of electric vehicle is overcharged, it will cause a large amount of gas to wash the battery plate, and this behavior will cause the active substances to fall off, which will eventually shorten the service life of the battery. In addition, overcharge of electric vehicle battery will also lead to the acceleration of water loss, affecting the decomposition of electrolyte, leading to the temperature rise of battery, and even spontaneous combustion, which is very important. According to the survey data, about 20% of the batteries of non-brand electric vehicles will spontaneously ignite after being used for a period of time, especially when overcharged in high temperature weather. Some of them are only deformed in their shells, but they also have great potential safety hazards.
3. Prevent misuse of different chargers.
Use regular and matched lithium battery chargers to charge batteries, and do not use inferior or other types of battery chargers to charge lithium batteries.
4. Avoid charging in high temperature environments.
The temperature of the battery itself is very high in the process of charging and discharging. If you choose to charge in a high temperature environment, it is easy to cause the battery to charge and shorten the service life of the battery.
5. Don't place it without electricity.
Lithium batteries are strictly forbidden to be in power deficit during storage. Power-deficient state means that the battery is not charged in time after use. When the battery is stored in power-deficient state, sulfation easily occurs, and lead sulfate crystals adhere to the polar plate, blocking the ion channel, resulting in insufficient charging and decreased battery capacity. The longer the idle time in power-deficient state, the more serious the battery damage. Therefore, if the battery is not used for a long time, it is best to charge about 40% of the battery and store it at 10~30℃, and recharge it once every two months, so as to keep the battery in good health.
