Who can tell me something about new energy electric vehicles (cars)?

At present, batteries that can be installed on electric vehicles: 1, lead-acid batteries, with large weight and small capacity. A few hundred kilograms of batteries can only let you drive more than 1 km, and the battery life will not exceed 500 times. That is, one and a half to two years, you have to change a set of batteries, and a set of batteries is tens of thousands.

2. Lithium iron phosphate battery, light weight, small volume, service life 1500 times. But the price is more than three times higher than that of lead-acid batteries. The final use price is comparable to that of lead-acid batteries.

At present, the battery cost of electric vehicles accounts for more than half of the cost of automobiles.
