How do you choose electric car battery?

Now electric cars have become one of the popular means of transportation on market, and electric vehicle battery is one of the most important parts. There are lead-acid battery and lithium battery sold on the market at present.

Battery voltage is 24 v, 36 v and 48 v, consumers have to choose according to oneself circumstance and personal interests. Close distance, the road is flat, can choose the battery voltage is small, lightweight car body; Distance is far, the need to bring or climbing a hill, have to choose voltage is larger, the body is relatively stable.

What's the difference between lead-acid batteries and the lithium battery? According to ms high experience, as well as of the data, the reporter is summarized what time the difference between the lithium battery and lead acid batteries, hoping to provide reference for consumers:

1, durability: lead-acid battery should generally deep discharge within 300 times, with memory, life in two years or so. And fluid in the lead-acid battery, use after period of time, if it is found that the battery hot or shorter charging time, needs to supplement liquid; Lithium batteries, strong durability of slow consumption, put more than 500 times, and there is no memory, general life in 4-5 years.

2, volume and quality aspects: general lead-acid battery is 16-30 kg weight, volume is larger; Lithium battery is in commonly 2.5-3 kg, the volume is relatively small, so light, easy to carry.

3, price, warranty period: the mainstream on the market at present is 48 v battery, if change, lead-acid battery is controlled 450 yuan, the quality assurance period for 1 year; Lithium-ion batteries are relatively expensive, need 1000 yuan, but the quality assurance period for two years.

4, driving km: the same is 48 v battery, in the case of a full charge, lead-acid battery and lithium battery electric vehicles can travel 30-40 kilometers. The motor speed depends mainly on use size.

5, battery capacity: lead-acid battery capacity is about 20; Lithium battery capacity of 8-10.

6, environmental protection, pollution existing in the production process of lead acid batteries, if improper recycling can also cause pollution; Lithium batteries were relatively green environmental protection.
