What kind of battery is best for electric vehicles?

Hubei "Shengbaolong" brand.

The secret of electric car purchase.

Tip 1: Learn more Before buying an electric car, learn more about electric vehicles from the Internet, newspapers or friends, and often see, hear, and praise the brand with good quality. Recommended Sources:

Electric Vehicle Business Network", "Chengdu **" electric vehicle column every Friday, etc.

Secret 2: Look at the brand Consumers should choose brands that have been in business for a long time, have a low repair rate, and have a good reputation. However, it should be noted that some of the brands that are well-known in the field of bicycles and motorcycles have average or even poor quality electric vehicles.

Tip 3: Choose a merchant with a certain scale and a long operating time to ensure that your after-sales service is guaranteed. Recommended brands: United Power Car Mass Sales, Shenda Automobile Dealership, Chengxin Automobile Industry, People's Shopping Mall, etc.

Secret 4: Heavy service electric car three points quality seven points service, good quality but after-sales brand, let you be as troubled. Since the current electric vehicle parts are not yet universal, the maintenance can not reach the socialization, so the purchase of electric bicycles must pay attention to ask whether the brand has a special maintenance service department in the region, how many after-sales service points.

Secret five: choose the model luxury type is fully functional, but the highest level is high, and the repair rate is high; The ordinary type has a concise structure, economical and practical, and has a low repair rate. The repair rate of simple electric vehicles on the market is much lower than that of luxury models.

Secret 6: Check accessories The same style of electric vehicles use different brands of accessories, ** the difference is very large, consumers should not be influenced by the style and ** when buying, to ask more about what accessories to use. Recommended Accessories Brands:

New Ocean, Minsida's motors; Pat Turn; Zhengxin tires, Songzheng controller; batteries for Panasonic, Jinchao, Jinma, and Qingba; Tiancheng, Chuanqi's chargers, etc.

Tip 7: Check the appearance Defective appearance not only affects the appearance, but also leads to shortened service life and increased after-sales costs in the future. Such as:

Whether there are defects in the welding and surface of the frame and fork, whether all parts are made well, whether the double supports are strong, whether the plastic parts are defective, etc.

Tip 8: Test the car Some cars will have imperfections in the assembly, pay more attention to whether the brakes are flexible when testing; Whether the sound of the motor is normal, whether the lights and instruments are normal, etc.

Tip 9: Ask the date of the electric vehicle battery will be damaged quickly if it is left uncharged for a long time, and the closer the factory date of the electric vehicle battery, the better.

Tip 10: Good custody After buying an electric vehicle, you should collect and keep the accessories, invoices, chargers, certificates, manuals, and three-pack cards that come with the car. Some manufacturers have established a user filing system, please follow the instructions for the record, in order to enjoy after-sales service.

Generally speaking, there are several types of batteries to suit different uses and occasions.

It depends on what kind of battery you use, and now the commonly used electric vehicle batteries on the market are lead-acid batteries and lithium batteries.

In terms of service life, lithium batteries have a longer service life than lead-acid batteries.

Lead-acid battery: generally within 400 times of deep charge and deep discharge, the life span is about three years.

Lithium battery: The average life is about 4 years, which is about one year higher than the life of lead-acid battery, and it is charged and discharged more than 500 times. Of course, if the battery you buy is a relatively poor battery, or if you don't pay attention to the maintenance of the battery in daily use, you will only be able to run more than 10 kilometers after more than a year.

Compared with lithium batteries, the defects of lead-acid batteries are obvious, that is, they are bulky, inconvenient to use, the battery capacity is limited, and the life is relatively short.

However, lead-acid battery batteries also have irreplaceable advantages of lithium batteries, which is why lead-acid batteries are still the mainstream shortage.

Advantages of lead-acid batteries:

1. Good safety performance. Lead-acid batteries are easy to feed, let you fall and hit the keys, repair it a little, and you can continue to use it.

2. Cheap. Lead-acid battery** is about 1 3 of lithium-ion batteries, which shows that its ** is very low.

3. Reversible repair. Lead-acid batteries can be used strongly, after the use of bad can go to the electric car store to trade in the new, make up the difference in price can be replaced with a new set of batteries, the loss is minimized, is a big benefit for the user. The lead in the battery can also be reused, reducing the pollution of the Huanshenliang Debate Environment.

At present, there are three main types of electric vehicle batteries commonly used on the market: lead-acid batteries, nickel-metal hydride batteries and lithium batteries.

1.Lead-acid batteries: This type of battery is inexpensive, but it is heavier and has a relatively short lifespan, usually only lasting 2-3 years. However, due to its cheapness, it can be used as a battery for entry-level electric vehicles.

2.NiMH battery: Compared with lead-acid batteries, NiMH batteries have a longer lifespan, high charging efficiency, small size, light weight, and environmental protection, but ** is relatively high.

3.Lithium battery: Lithium battery is currently the most commonly used type of battery in the electric vehicle industry, with good performance, long life, small size, light weight, short charging time, but relatively high.

Overall, if you have a good budget, it is better to choose a lithium battery because it is lighter, lasts longer, charges faster, and is relatively environmentally friendly. If you have a limited budget, you can choose NiMH batteries or portable lead-acid batteries.

Electric vehicles, I personally think, are more durable with lithium batteries.

The better brands of electric vehicle batteries are Xingheng Lithium Battery, Nandu Battery, Kangyang Battery, Jingqiu Battery, and Tianneng.
