Lithium electricity will lead the trend. Lead-acid batteries will be replaced by lithium ion batteries. Electric vehicle lead-acid battery can be changed to a lithium ion battery, it is simple and convenient.

The lithium-ion battery pack of various specifications can be bought online, as long as the voltage can be directly replaced by lead-acid batteries. In general, simply replace the charger into a supporting lithium-ion battery charger. But there is a little attention, that is the controller problem.

There is a controller that is specifically combined with lithium electrical use, and the controller for changing lithium ion battery after changing lithium is better. In fact, the lithium battery controller is the same as the principle of lead-acid battery controller, and the hardware is also the same, and only the undermetallization value is different. Lithium-specific controller is lower than lead-acid batteries.

Battery utilization is higher. Battery can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metal-state lithium, and can be charged.

The fifth generation of the rechargeable battery is born in 1996, its safety, specific capacity, self-discharge rate and performance ratio are better than lithium-ion batteries. Due to its own high-tech requirements, only a few countries are producing this lithium metal battery. Advantages of lead-acid battery advantages: cheap price, while bringing recyclable and reuse attributes, after using bad, you can go to the electric motor store to replace the new battery, reduce the difference, minimize the loss, Is a small benefit.

I can continue to use the fight against fighting. Even if you break it, you can continue to use it. Disadvantages: The volume and weight of the lead-acid battery are very large.

The weight is generally at 16-30kg, followed by the lead-acid battery, deeply charged in 400, memory, service life is about 2 years (most) In the case of 1.5 years). And the lead-acid battery contains a liquid, and the battery is consumed for a period of time.

Advantages of advantages of lithium ion battery: small size, light weight, comparison of lead-acid batteries, lithium-ion batteries, is 2/3 of lead-acid battery volume, weight is about 1/3 of the weight of the lead-acid battery. The same volume of lithium-ion battery is more than the capacity of lead-acid batteries, and the reduction in weight makes the electric vehicle endurance capacity increases about 10%. In terms of charge and discharge, the durability of lithium-ion battery is stronger than lead-acid battery, and the lithium-ion battery can continue to charge for 48 hours without the cracking of the battery expansion leakage.

The capacity is maintained at 95% or more. And under special chargers, fast charge and discharge can be performed. Deep charging is more than 500 times, and there is still no memory, the general life is basically around 4 to 5 years.

Disadvantages: The high production cost of the lithium-ion battery is high, and the production equipment is about 40% of the production cost, and the price is probably three times the lead-acid battery. And the recovery value of the lithium-ion battery is not high, and the domestic recovery environment is also more chaotic. Most lithium-ion batteries can only be thrown, or find a place to bury.

Inferior lithium-ion batteries, the sealing conditions in electric vehicles are not very good, easy to damp, causing adverse contacts, etc. After introducing the battery structure and advantages and disadvantages of the lead-acid battery and lithium-ion battery, the author will calculate the cost of replacement, see that the investment cost of the lead-acid battery is high, or the cost of investment in lithium-ion batteries is high. We conducted 8 electric vehicle cross-evaluation activities in August 2017, in which the turtle turtle of the green source was 21.

49km / h, the battery capacity was 60V20AH, and its battery capacity was a common 60V20AH. Motor power is 800W. Next we are based on the battery capacity and motor power of this car.

Lead-acid battery life: According to the relevant information, 2015 Beijing office commuter distance one way is around 19km, and in 2017, this data is only a lot. Take the author as an example, my top and trip to and from the commuteth is about 50km. If I ride a 60V20ah, the motor power is 800W, the motor vehicle is commuted, the speed is kept at 30km / h, then I can Consumption of a cycle charge and discharge.

According to the 21st workdays of one month, add the long-term riding time of the weekend and holidays, and the circulation of the electric car is about 300 times in the year, and we introduce the lead-acid battery. The service life is charged and discharged from 400 cycles, so in such a high-frequency cycle, a lead-acid battery life is up to a year and a half. Lithium-ion battery life: Lithium-ion battery usually we have contacted, as an example, a mobile phone is in use for 1-2 years, it is not as good as before, but few people will consider replacement within two years.
