How to maintain lithium iron batteries? Electric car lithium battery maintenance methods. Today, the main lithium battery products on the market are lithium iron phosphate and ternary lithium batteries. Lithium industry is the general trend; lithium battery will gradually become the mainstream of the electric vehicle battery market under years of technical accumulation. Today, Cunningham Electric shares with you the knowledge of how lithium batteries should be maintained.
How to maintain lithium iron battery?

1. Don't overcharge and over discharge lithium iron batteries. When not in use, keep the power at about 50%, the voltage is about 3.2V. Do not be too low.
2. When charging and discharging also to the lithium battery charger current and the current load of the appliance within the prescribed range, too high a current load is likely to cause a short circuit inside the lithium battery, thus destroying the internal structure of the lithium battery, causing safety hazards in the circuit.
3. The application of lithium iron phosphate battery temperature range is relatively wide, outdoor in the winter in the north, can still be used, but the capacity will be reduced by a lot, and then back to room temperature conditions, the lithium battery capacity can be restored. Lithium batteries are extremely sensitive to temperature, try to avoid long-term use below zero degrees, which may have a great impact on battery life and harm.
4. Lithium iron batteries should be stored in a cool, monotonous, safe environment, it can be stored in a clean, monotonous, ventilated environment with a temperature of -5 to 35 ℃ and a relative humidity of not more than 75%. Note that the storage of batteries in a hotter environment will not prevent the formation of corresponding damage to the quality of the battery.
5. Lithium battery storage process should prevent metal objects into the battery box, which may cause battery leakage, heat, smoke, fire and burst.
6. In order to protect the lithium battery from damage due to external electrical environment disorders, the battery body will be set up inside the management of the battery status chip. This chip also has the function of recording battery capacity and correcting battery capacity.
Electric car lithium battery maintenance methods
●Electric car lithium battery should pay attention to the charging method. Try not to charge the battery in low temperature conditions, and the same goes for high temperature. When the temperature exceeds 30℃, charging needs to increase the current input.
●Charge after each ride until the electric car lithium battery pack is not discharged, but avoid deep discharge (more than 90% of capacity) before charging, which will damage the lithium battery.
●Because the lithium battery has the characteristic of no memory, the battery pack should be charged regularly after each ride or every day in time.
● Master the correct way to charge the lithium battery of the electric car. Connect the charger to the battery pack first, and then connect the charger power plug to 220V AC power. This connection order can avoid electric sparks when plugging and unplugging the charging plug.
● Use a special lithium charger (do not use a lead-acid battery charger directly), and match the lithium battery model exactly. The charger current is too large to break the lithium battery protection system and cause a short circuit, thus causing a safety accident to the lithium battery.
The state of power loss refers to the electric car lithium battery is not charged in time after use, resulting in insufficient charging and a decrease in battery capacity. The longer the battery is idle, the more serious the battery damage will be. When the battery is idle, it should be charged once a month, which can prolong the service life of the battery.
The above is the maintenance method of electric car lithium battery, choose a reliable electric car lithium battery is the most critical. The quality of electric car lithium battery directly affects the travel experience of consumers.
