Nowadays, there are many brands of electric vehicles, and almost every one has electric vehicles equipped with lead-acid (Tianneng battery, Chaowei battery) and lithium battery. Each style is very large and dazzling.
At present, there are many types of electric vehicles on the market, such as motorcycles, bicycles, and folding. The battery voltage is 36 volts, 48 volts and 64 volts. Consumers have to choose according to their own situation and personal preference. The driving distance is relatively close, and the road surface is relatively flat. The battery voltage can be selected to be small and the vehicle body is light. If the driving distance is far, if you need to bring people or climb the slope, you have to choose a larger voltage and the body is relatively stable.
So, what is the difference between a lead-acid battery and a lithium battery? The global electric vehicle network summarizes the differences between lithium batteries and lead-acid batteries, and hopes to provide consumers with reference:
1, durability: lead-acid batteries generally deep charge deep discharge within 300 times, there is memory, life expectancy is about two years. And there is liquid in the lead-acid battery. After a period of consumption, if the battery is found to be hot or the charging time is short, the liquid needs to be replenished. The lithium battery has strong durability, slow consumption, more than 500 times of charging and discharging, and no memory. Life expectancy is 4— 5 years.
2, volume, quality: the general lead-acid battery weight is 16 & mdash; 30 kg, larger. Lithium batteries are generally 2.5— 3 kg, and the volume is relatively small, so the ride is light and easy to carry.
3, the price, warranty period: the current mainstream battery on the market is 48 volts, if replaced, the lead-acid battery is about 450 yuan, the warranty period is 1 year. Lithium batteries are relatively expensive and cost around 1,000 yuan, but the warranty period is two years.
4, driving kilometers: the same 48 volt battery, in the case of full charge, lead-acid batteries and lithium-ion battery electric cars can drive 30 & mdash; 40 km. The speed depends mainly on the size of the motor used.
5, battery capacity: lead-acid battery capacity is about 20 amps; lithium battery capacity is 8 & mdash; 10 amps.
6. Environmental protection: There is pollution in the production process of lead-acid batteries: if it is improperly recycled, it may cause pollution; lithium batteries are relatively green.
