Lithium battery packs and lead-acid batteries are the two most popular batteries to be compared. In the past, lead-acid batteries dominated the market, but now lithium batteries are being packaged a little bit of phagocytosis. Lithium battery packs is the pace of the times development, selected and accepted by the majority of customers. .
Today we are going to discuss a question: who will go farther in the same capacity lithium battery pack and lead-acid battery?
It is understood that the internal resistance of lithium battery pack is slightly larger, and the discharge curve is stable, and the velocity difference between front and back is even.
Lead-acid batteries have a small resistance and a quick start, but they struggle with the drop in voltage. The lithium-ion battery pack will be slightly longer if the two batteries fight from the discharge curve and the journey.
For example, the determination to slow down the discharge of lead-acid batteries can also add some mileage, instantaneous high-voltage banishment, because the electrolyte in the plate vacancy is rapidly diluted, and more than 90% of the solution outside the plate hole lead sulfide molecules can not spread to the plate vacancy. Thus, the specific resistance of the solution in the plate hole is added, and the terminal voltage is lower than that of the lead-acid battery. Other lithium batteries with different capacities only need 1/5-1/10 of the lead-acid battery, so the lithium battery pack must be farther than the lead-acid battery mileage!
Let's compare the lithium battery pack and the lead-acid battery in detail.
1. Lead-acid batteries are low-cost, robust and mature receiving and receiving system, low internal resistance, low requirements for working premises, no need to protect the circuit, almost maintenance-free, is based on lead-acid batteries rather than lithium batteries in adverse circumstances, such as car startup batteries, field generator startup batteries, today's on Popular electric vehicle batteries, UPS power batteries and so on.. But there are also low specific capacity, quality, volume are fighting, charging this battle is low, the future with the growth of lithium batteries, lead-acid batteries is bound to be narrower and narrower.
2. The benefits of lithium-ion battery packs must have been experienced by all, notebooks, mobile phones and various digital products, and now standard lithium-ion battery packs! So far, no battery can span lithium-ion battery packs in terms of capacity and charge times, especially ternary lithium-ion batteries, although BYD lithium-iron phosphate batteries are safer. But the capacity gap still leaves only one part of the Enron problem behind.
Battery handling units are also gradually improving. Battery care, balance and heat handling are getting better and better. Of course, you don't have to think that the popular lithium batteries for electric vehicles have heat handling.. No, only the ones on the electric vehicles, the balance of the popular lithium batteries. Thank you for your better quality.
Also, let's know something about the use of lithium battery pack:
(1) we should also pay attention to the fact that it does not discharge too much during the use of lithium batteries.
Second, be careful not to mix with the lead-acid charger.
(3) Not professional personnel do not remove and repair lithium battery packs, other special attention should be paid to some varieties of lithium batteries in the absence of care in the case of low current use voltage will suddenly fade, that is, recharge can not be saved;
Don't idle or charge for a long time. This is the same as lead-acid batteries. After a long time, the batteries will be discarded.
_Temperature should be appropriate, lithium battery pack charge temperature is 0 ~45, lithium battery discharge temperature is - 20 ~60.
_In a clean, dry, ventilated environment, should avoid contact with corrosive substances, away from fire and heat sources.
Choose the same capacity lithium battery pack and lead-acid battery, lithium battery pack mileage farther is inevitable.
