Now there are not a few electric vehicles bought privately modified, of which the most modified part is the electric vehicle battery. Change lead-acid batteries into lithium batteries, or lithium batteries into lead-acid batteries are available. Many say that battery modification is bad, no good. In this case, many owners will not rush to modify the battery. So what are the main benefits? We take lead-acid to lithium batteries as an example!

What are the advantages and disadvantages of battery modification? Let me be clear with you today.

First, greatly enhance the number of battery cycles and mileage

In terms of performance, the energy density of lithium batteries is higher, the volume is smaller, the same battery compartment, the capacity of lithium batteries can be 3-4 times that of lead-acid batteries, which also means that the mileage can be increased by 3-4 times. The original can run 100 kilometers, now stuffed with lithium batteries, can run 300-400 kilometers. At the same time, its cycle life from about 500 times can now be increased to 800-1500 times.

Second, reduce charging to avoid battery anxiety

In particular, friends who do flash send especially like lithium batteries, because lithium batteries have a long life, and they can run 1-2 days without charging on a single charge. If it is a lead-acid battery, it needs to be charged 2-3 times a day, which greatly reduces the efficiency of distribution. Therefore, the delivery boy prefers to change the lead acid into lithium batteries.

Of course, electric vehicle battery modification also has a certain risk, mainly for policy and safety, there are two main!

First, electric vehicle lead-acid to lithium battery, there is a certain risk of deflagration

First of all, lithium batteries and lead-acid batteries charge and discharge power is different, can not use the same charger for charging, lithium batteries in the case of high-power charging is prone to deflagration. Therefore, when the lead acid is changed to lithium, if there is no overcurrent protection for the electric vehicle, then the risk of deflagration of the lithium battery due to overcharge overheating is relatively large.

The hub motor of an electric vehicle is both a motor, and it is also a generator. When the hub of an electric vehicle is downhill and braking, release the accelerator, the hub motor can automatically generate electricity and reverse charge the battery, but the current is unstable. In the absence of protective measures, the lead-acid battery after a large current impact, at most scrapped, but will not deflagration. But the same cannot be said for lithium batteries.

Second, electric vehicle lead-acid lithium battery is a serious modification behavior

We all know that every electric two-wheeled vehicle is to pass the certification of the Ministry of Industry and Information Technology catalog, generally have 3C logo, certificate has indicated the type of battery. If the user secretly modifies, so that the type of battery, battery model changes, then it is a modification of the behavior. In Zhejiang Province, users can be fined 300 to 500 yuan. And you have to impound your vehicle.

In SUMMARY:

The modification of electric vehicle batteries is like a tightrope walk, which is a highly dangerous behavior. Although people are not satisfied with the speed and endurance of existing electric bicycles. However, we can choose the original lithium battery model for distribution, and can meet their own distribution needs under the premise of ensuring safety, why not? Guys, what do you think about that? Welcome to the comment section!
