The electric car with lead-acid batteries good or good with lithium batteries

Conditions are not electric vehicle charging for the explosion. But with combustion conditions. Lead-acid battery electric cars adopt is the only low-speed electric cars, such as old car instead of walking, can legally on the road of electric cars is the lithium-ion batteries are used. Electric vehicle charging can cause fires, but lower risk in particular. Burning reason is nothing but there is something wrong with the power management module, battery charging, too much electricity, battery will happen after thermal runaway acuteness of spontaneous combustion, thus the entire car ignition. News reports in the electric car spontaneous combustion is the accident caused by many reasons, such as battery punctured in the accident, the battery will prick blazing, and it's hard to save the fire, but a fire burns can only use a lot of water cooling, fire extinguisher has almost no effect. But the fire could not have come so in a timely manner, so the accident caused by spontaneous combustion, can be slow because the fire vehicle mostly reduced to ashes. Also some brands of electric cars in the parking time of spontaneous combustion, this is why a lot of, in a few words couldn't say for sure and most manufacturers also won't announce the cause of spontaneous combustion, such as to experiment with. Lead acid battery and lithium battery. Lead-acid battery only elderly walking vehicle in use, the compliance of the cars are all made of lithium battery. Two batteries which good, what kind of car do you want to see. Lead-acid battery energy density, big volume, low weight, cheap, simple charging and discharging control. But it wasn't on the compliance of the electric car, the compliance of the electric car motor power, high speed, long range and, at the same time won't have much space for the battery, so the higher capacity density of lithium battery is more suitable for electric cars. But for low-speed electric cars, lead-acid battery is a better choice. This kind of car motor power is small, only a few kilowatts, at the same time speed is not high, the vehicle weight is not high, low power consumption. There is enough space to put the battery. Lead-acid battery is especially suitable for, the price is cheap, even scrapped after can sell a good price, at least you can sell new battery a third of the price. But change with lithium batteries, cost is high, but this kind of electric charge and discharge control is not very accurate, is limited by the cost, this type of the lithium battery electric vehicle choose quality will not be too high. So short life common lithium-ion batteries, and can't realize the theory of cycles, a damage, but the battery is almost electronic garbage, not like a lead-acid battery can fetch a good price.
