Electric car lithium iron phosphate ion battery and automobile ternary lithium ion battery maintenance method. At present, the mainstream power of new energy vehicles is an electric system, and people know more clearly, restricting the development of electric systems, but the core of the core. At present, electric vehicles selling on the market are basically using lithium-ion batteries, but there are two types of lithium-ion batteries, which are ternary lithium-ion batteries and lithium iron phosphate ion batteries.
Today, Xiaobian will introduce electric car lithium iron phosphate ion batteries and automobile three-dimensional lithium-ion battery maintenance method. Maintenance method of electric car lithium iron phosphate ion battery, correctly grasp the charging time during use, should accurately grasp the charging time according to the actual situation, refer to usage frequency and mileage case, grasp the frequency. When driving normally, if the electricity scale indicates that the red light and yellow light are on, it should be charged; if only the red light is on, it should stop running, charge as soon as possible, otherwise the battery is over-discharge will seriously reduce its life.
When the power is fully charged, the run time is shorter. The charging time should not be too long, otherwise it will form over-charging, so that the battery is heated. Excessive charging, excessive discharge and insufficient prevention will shorten battery life.
Generally, the average charging time of lithium iron phosphate ion battery is about 10 hours. The charging process such as the battery temperature exceeds 65 ¡ã C, stop charging. Second, the instructions for protecting the charger generally have instructions on protecting charger.
Many users don't look at the habits of the manual. In addition to the problem, I want to find the instructions in the future, often too late, so I will first look at the instructions is very necessary. In order to reduce costs, the current charger is basically not designed with high vibration, so that the charger should not be placed in the trunk and the basket of electric bicycles.
In special cases, you must move, but also pack the charger with foam plastic, prevent the bump of vibration. Many chargers have passed through vibrations, and their internal potentiometers will drift, so that the entire parameter is drifted, resulting in abnormal charging state. In addition, it is to pay attention to the charging of the ventilation of the charger, otherwise it will not only affect the life of the charger, but also the thermal drift can affect the charging state.
This will form damage to the battery. Therefore, it is also very important to protect the charger. Third, the regular deep discharge battery regularly conducts a deep discharge is also conducive to the "activation" battery, which can slightly improve the capacity of the battery.
The general method is to periodically discharge the battery. The fully discharged method is to ride the first undervoltage protection under normal load of flat pavement. Note that we especially emphasize the first undervoltage protection.
After the first undervoltage protection, the battery will rise after a period of time, and restore to the non-output state, this time, if the battery is used, it is very harmful to the battery. After completing complete discharge, fully charge the battery. It will feel that the battery capacity is improved.
Fourth, the plug is hot 220 volts supply plug or the charger output plug is loose, and the contact surface oxidation can cause the plug to hang, the heat transfer time will cause the plug short circuit or the contact, damage the charger and battery, bring you Unnecessary loss. Therefore, when you find the above, you should clear the oxide or replace the connector in time. 5.
Even if you charge it, even if your renewal capacity is not long, you can use it 2 to 3 days, but it is recommended that you charge every day, so that the battery is in a shallow cycle, the battery life will be extended. Some early use of mobile phone users think that the battery is best to use after it is fully charged. This view is wrong.
The memory of the battery is not so strong. Always put the life of the battery is relatively large. Most chargers indicate that the light-made light indicates that the battery can be charged into the electricity of 97% to 99%.
Although only 1% to 3% of the electricity, the impact of the continuation capacity is almost neglected, but it will also form an under charge accumulation, so the battery is filled with the electric shifting, and the floating charge will be continued as much as possible, and the vulcanization of the battery is also beneficial. Sixth, it is strictly forbidden to be in a loss when it is stored in a strictly forbidden storage. The loss of the loss means that there is no timely charging after the battery is used.
The battery is placed in the loss of the loss, it is prone to sulfate, the lead crystal of sulfate is attached to the plate, which will block the ion channel, causing insufficient charging, and the battery capacity is lowered. The longer the loss time of the loss, the more the battery is damaged. Therefore, when the battery is idle, it should be added once a month, so that the battery health is better.
7. Prevent a large current discharge electric car starts, manned, uphill, try to prevent it from accelerating the acceleration, forming instantaneous current discharge. Large current discharges can result in lead crystals of sulfate, thereby damaging the physical properties of the battery pole plate.
Car three-dimensional lithium-ion battery maintenance method At present, the mainstream type of new energy vehicle lithium-ion battery is a three-dimensional ion battery and a lithium iron phosphate ion battery. Among them, the three-dimensional lithium-ion battery has a considerable part, because the ternary lithium ion battery is smaller, the ability density is higher, low temperature resistance, and the cycle performance is also better, so becoming the mainstream of the new energy passenger car. If the battery is not used for a long time, it is preferable that the amount of electricity charged from about 40% is stored at a temperature of 10 ~ 30 ¡ã C, and the electricity is supplemented every half a year; protective chip lithium ion battery to charge and discharge The current voltage has extremely strict requirements, in order to protect the battery is not damaged due to external electrical environment, the battery body will set the chip of the battery status.
This chip also has functions of recording battery capacity and correcting battery capacity. Now, even the cottage mobile phone battery does not save this key to protect the chip, otherwise the cottage mobile phone battery is not used for a long time; the memory effect is common on nickel-hydrogen charging battery. Specific performance is: If you start using a battery for a long time, the battery will be significantly declined, even if you want to be full, it is not full.
Therefore, the important way to maintain the nickel-hydride battery is that electricity must be used up before they can start charging, full of electricity is allowed to use. The memory effect of the commonly used lithium-ion battery is now small to ignore. Lithium ion batteries are used to apply lithium-ion batteries because of their large capacity, no memory effect, more and more areas.
In the energy storage market, benefited from some power lithium battery companies to start layout energy storage business, and the market demand of lithium iron phosphate ion batteries begins to amplify.
