Now, electric vehicles have become one of the most popular means of transportation in the market, and lithium battery is one of the most important components.
At present, the electric vehicle batteries sold on the market are lead-acid batteries and lithium batteries.
The battery voltage has 24 volts, 36 volts and 48 volts, consumers have to choose according to their own situation and personal preferences. If the driving distance is close, the road surface is flat, you can choose the battery voltage is small, and the electric vehicle body is light. 24v lithium ion battery is a good choice.The driving distance is long, and you need to take people or climb the slope, you have to choose the voltage is larger, and the electric vehicle body is also relatively stable.
So what’s the difference between a lead-acid battery and a lithium battery?
According to battery energy experts summed up several differences between lithium batteries and lead-acid batteries, hoping to provide a reference for consumers:
1, durability: lead-acid battery generally deep charge and discharge less than 300 times, have memory, life is about two years.
And there is liquid in the lead-acid battery, after consumption for a period of time, if you find that the battery is hot or the charging time is shorter, you need to replenish the liquid: the lithium battery has strong durability, slow consumption, charge and discharge more than 500 times, and no memory, and the general life is 4-5 years.
2. Volume and quality: generally speaking, the weight of lead-acid battery is 16Mui 30kg, and its volume is large.
Lithium batteries are generally 2.5-3 kg, and their size is relatively small, so they are light to ride and easy to carry.
3, price, warranty period: at present, the mainstream battery on the market is 48V, if replaced, the lead-acid battery is about 450yuan, the warranty period is one year: the lithium battery is relatively expensive, it needs about 1000 yuan, but the warranty period is two years.
4. Driving kilometers: the same 48-volt battery, when fully charged, lead-acid battery and.
Electric cars with lithium batteries can travel 30-40 kilometers.
The speed mainly depends on the size of the motor used.
5. Battery capacity: lead-acid battery capacity is about 20 An and lithium battery capacity is 8-10 A.
6. Life and safety: lithium batteries are also lead-acid batteries. Relatively speaking, the frequency of use of lithium batteries is far higher than that of lead-acid batteries, and the quality and safety of lithium application pools is also guaranteed.
7. Environmental protection: lead-acid batteries are polluted in the production process, which may also cause pollution if they are not recycled properly: lithium batteries are relatively green.
Maintenance skills of lithium battery for electric vehicles: it is forbidden to lose power during storage.
Lithium batteries are afraid of overcharging and even more afraid of overdischarge.
However, lithium batteries have no memory effect and can be charged whenever they are used.
Do not charge until the electricity is completely used up, so it is easy to overdischarge and hurt the battery; do not discharge with large current, in places with a large slope, it is best to use pedal power to avoid battery power.
