What kind of battery is the best for electric vehicles? I believe everyone is no stranger to electric vehicles, and batteries are the energy of electric vehicles. A good battery can run longer, and many people are curious about which battery is good. Next, I will take you to know in detail which battery is the best for electric vehicles.
What kind of battery is the best for electric vehicles? 1 1, lead-acid battery.
Lead-acid battery is called sealed maintenance-free lead-acid battery, which has the advantages of low price, large capacity and mature technology. Especially in recent years, battery manufacturers have made new breakthroughs in battery performance and greatly improved battery service life through process reform, formula optimization and charging technology progress. Lead-acid battery is also the main power source of electric vehicles on the market at present, but the fly in the ointment is that the weight of lead-acid battery is still a little heavy.
2. Lithium battery
Lithium battery is a battery with lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. Lithium batteries have the advantages of small size and light weight, and are more efficient, safer and more environmentally friendly than traditional lead-acid batteries. The portability and durability of lithium batteries also make electric vehicles more beautiful and lightweight, which is very suitable for the elderly and female friends. The disadvantage of lithium battery is that its price is slightly higher.
3. Nickel-cadmium battery
Nickel-cadmium battery has light weight and long service life. Nickel-cadmium batteries can generally be charged and discharged for more than 500 times, which is relatively durable. Disadvantages are high price, low capacity and short cruising range. Nickel-cadmium battery has memory effect and can only be charged after discharge. Nickel-cadmium batteries are rarely used in domestic electric vehicles.
4. Ni-MH battery
The energy of Ni-MH battery is higher than that of Ni-Cd battery, and its cruising range is slightly longer. At the same time, it also overcomes the shortcomings of memory effect of nickel-cadmium battery, and the price has recently decreased with the increase of output. At present, some electric vehicles have begun to use Ni-MH batteries.

What kind of battery is the best for electric vehicles? 2 How to charge the battery of electric vehicle?
Don't think about using up all the electricity, and then recharging when there is nothing left ~ This is not right ~ It is easy to damage the battery ~ You should pay attention to your power indicator, and recharge when the power indicator shows that there is one third of the remaining power.
The charging environment should be kept dry and tidy, and the charger should not be wrapped in plastic bags or plastic bottles. This is because when the charger is airtight, it is easy to burn because of poor heat dissipation.
Try not to use fast charge, unless necessary, not more than twice a month. Always use fast charge, the battery life will be shortened quickly. Protect your battery, this is to ensure driving safety!
Put the charger in a fixed place to avoid bumping. If you want to go out and carry it, put it in your bag properly! Otherwise, the road is bumpy or something, and it is easy to go wrong. When I arrived at my destination, I happily took out the charger and found that it didn't work at all. It was really bitter.
Use a standard electric vehicle charger to charge. This is quite critical! Many people think it doesn't matter, just pull a wire or something and see if the plug can be plugged in. However, the charging equipment configuration of different electrical appliances is different, and indiscriminate use of the charger will cause damage to the battery, and even lead to serious consequences such as battery burning.
How long can the battery of an electric car last?
Generally speaking, the faster the car runs when it is replaced every two years, such as the battery of an electric motorcycle, it will fall off after one year.
How long you can use it depends on your habits:
The length of use is also related to your usual maintenance. The battery on the battery car can be charged at any time, and there is no memory. You can charge it after riding, but dial it when it is full. Never overcharge! After the battery is charged, it will cause great damage to the battery. If the battery is well maintained, the distance it runs every day is not too far, and it is possible to use it for 3-5 years. But the more electricity you use, the less satisfied you will be. In the end, you will not reach the distance you want to run, and you will want to change if you are not allowed to change.
Maintenance skills of electric vehicle battery
The mileage of a fully charged electric car can be changed as long as it does not affect your commute or work at ordinary times. The battery of my earliest electric car has been used for six years, and now it can run 20 kilometers. ), if the mileage affects the use, it is necessary to consider replacing it. Replacing 36V batteries (three batteries) is generally in the repair shop of electric vehicle manufacturers around 300 yuan, and the general repair shop of electric vehicles around 230 yuan.
Of course, if the quality is reliable, it is still the maintenance point of the manufacturer.
The electric car consumes a lot of power when starting, which not only saves electricity, but also pedals when starting, greatly prolonging the life of the battery. There are many advertisements saying that old and new batteries can be returned. I've never tried it. The cost is only tens of yuan, which is more cost-effective than the replacement. it wont hurt you to try it
If you want to replace a new battery, you should also pay attention to whether the capacity (AH) of the new battery is the same as the original one. The existing profiteers use small-capacity batteries to change them for you. The price looks cheaper, but the mileage is greatly reduced.
