Light vehicle battery manufacturers take you to understand which is better for electric bicycle lithium battery or lead-acid battery
The manufacturer of Light vehicle battery tells you the so-called good or bad, it depends on which aspect, the technical content of lithium battery is high, and it has been called for so many years to promote lithium battery, but it is always a niche market, and lead-acid batteries are still big heads. According to some According to statistics, the market for lithium batteries does not exceed 10%.
1. Technical content
Light vehicle battery manufacturers tell you that lithium batteries are stronger than lead-acid batteries in many places. In terms of the same capacity, lithium batteries are less than 70% of lead-acid batteries in volume, and lithium batteries weigh less than 40% of lead-acid batteries, so lithium batteries The cruising range can be much longer than that of lead-acid batteries. Lithium batteries have more than 600 charge-discharge cycles and are relatively durable.
Light vehicle battery manufacturers tell you that lead-acid batteries have small capacity, large volume, and a much shorter service life than lithium batteries. The charge and discharge cycle cycle has also been reduced, and the service life is shorter. Generally, it may be broken after a little more than a year.
Second, the price
Light vehicle battery manufacturers tell you that the price of lithium batteries is about 2-3 times that of lead-acid batteries. Generally, a lead-acid battery electric vehicle costs a few hundred yuan to replace the battery, while a lithium-ion vehicle can cost thousands of yuan at every turn. This is for ordinary wages. As far as the family is concerned, it is not a small expense.
And the lithium battery has almost no recycling value. If the lead-acid battery is broken, you can replace it with a little money. In this way, although the lithium battery has a long life, it does not take much advantage compared to the recycling of the lead-acid battery. NS.
The light vehicle battery manufacturer tells you that although the lithium battery has a large capacity, it is a little bit disturbed and may be broken. Therefore, a reasonable battery management system is required, and there are requirements for temperature and vibration. Light vehicle battery manufacturers tell you that if the design is not good, or the quality of the battery is defective, or improper use, it may cause fire and explosion. For ordinary people, it is indeed a scare thing. Moreover, the lithium battery cannot be discharged at a high current, that is, the instantaneous output current cannot be that large, so the power advantage is not necessarily obvious.
In contrast, in the use of lead-acid batteries, it seems that many people have no major problems in series and parallel connection. If the capacity drops, just add some water or repair them, and they will be refreshed again, and there is no need to worry about fire and explosion. (Of course there may be problems with overcharging)
The lead-acid battery is broken, just buy the battery and replace it, at most it is not far away. The management system of each lithium battery is different. If it is broken, it is really difficult for you to repair it. This thing is dangerous, so you often need to send it back to the manufacturer for repair or replacement. Not to mention the cost of travel, just delay time, it is still a trouble. Things up.
Light vehicle battery manufacturers tell you that ordinary people will choose products from the cost-effectiveness. Lithium batteries are not good enough for lead-acid batteries. This is the reality after considering various factors. Look at those low-speed electric vehicles equipped with lead-acid batteries. They are also very prosperous. The formal so-called new energy vehicles do not sell well without them. This is also the reason.
However, after the launch, the market is completely changed from the supply side. The Light vehicle battery manufacturer tells you that only small size and light weight can be used on the streets, so lithium batteries should usher in a new stage of development.
