Lithium battery pack is widely used in various fields today, how to make lithium battery pack life longer? How to use lithium battery pack more secure?
How to maintain the lithium battery pack?
The above mentioned problems need to understand, after all, lithium battery pack price is not cheap, can extend the life of lithium battery pack as far as possible, it is equivalent to save a sum of money for the enterprise.
Introduction to the principle of lithium battery pack
Lithium-ion battery pack is a kind of lithium metal or lithium alloy as the anode material, the use of non-aqueous solution of the battery, is two battery technology, the highest energy density, the best comprehensive performance of the battery, its market share since the date of birth will be increased year by day.
Lithium battery Pack Maintenance method
1 Charging aspect
Choose the appropriate charger: Select the Power matching charger, can make lithium battery pack charging more stable, not prone to accidents. But the charge: Lithium battery pack does not have memory effect, do not need to overcharge to activate the battery, do not need to overcharge to remember the maximum capacity of the battery.
While the charger for most lithium battery packs has a charge protection or this aspect of protection, it is better to develop a good charging habit in case of the longer life of the lithium battery.
2 discharge aspects In addition to not over-charging, excessive discharge is also undesirable.
Due to the need to maintain a certain amount of lithium ions in the cathode to maintain the stability of the structure, over-discharge so that more lithium ions moved out, destroying the stable structure of the anode, causing irreversible damage to the anode.
3 Operating Temperature environment Charging ambient temperature: the best charging environment for Li-ion batteries is 5-45 degrees Celsius. Although 0-5 degrees Celsius can still be charged normally, the charge current needs to be reduced relative to the (5-45 degrees Celsius environment) to maximize battery life. Charging at high temperatures or above 45 degrees Celsius can degrade battery performance and even degrade electrolyte in the battery. Low temperatures or below 0 degrees Celsius can cause internal resistance to increase, resulting in longer charging times.
In addition, under 0 degrees Celsius under the environment of charging, the battery will be in a sub-freezing condition, will cause irreversible damage to the battery. Discharge environment temperature: Lithium battery pack discharge environment temperature is generally -20℃~60℃, but generally less than 0 ℃ lithium battery performance will decline, discharge capacity will be correspondingly reduced, so the performance of lithium battery fully operating temperature, common is 0~40℃.
Some special custom-made lithium battery temperatures are different, and some can even operate in hundreds of degrees Celsius environment.
4 Storage and Maintenance
Lithium battery can be stored at a temperature of -5~ 35 ℃, the relative humidity is not greater than 75% clean, dry, ventilated environment, should avoid contact with corrosive substances, away from fire and heat source, do not place in direct sunlight.
(5) Lithium battery pack do not mix the battery with metal objects, so that metal objects touch the positive and negative polarity of the battery, resulting in a short circuit, damage to the battery or even cause danger.
(6) Lithium batteries do not tap, acupuncture, pedaling, modification, solar battery, do not put the battery in the microwave, high pressure and other environments.
(7) Use a regular matching lithium battery charger to charge the battery, do not use inferior or other types of battery charger to charge the lithium battery. The above is the lithium battery pack maintenance needs to pay attention to a few points, the use of good lithium battery pack is useful for prolonging the service life.
What we need is to maximize the life of the lithium-ion battery pack when it comes to meeting the needs of the lithium-ion battery pack.
The lithium battery itself is also a kind of consumables, no matter what approach we take to avoid its eventual loss, but we use the right method, delaying its aging.
