Electric vehicle batteries are the most important part of electric vehicles. The quality of an electric vehicle battery determines the performance and life of electric vehicles.There are many types of electric vehicle batteries on the market. Various electric vehicle battery brands are dazzling in the market. How can we choose high -quality electric vehicle batteries?I will take you to understand the purchase of electric vehicle batteries below.
What are the types of electric vehicle batteries
Lead-acid batteries
The full name of the lead -acid battery is called a seal -free maintenance leader -free battery. Its advantage is that it is low in price, large capacity, and relatively mature technology.Lead -acid batteries are also the main source of power of electric vehicles on the market. The disadvantage of the lack of beauty is whether the weight of the lead -acid battery is slightly heavier.
lithium battery
Lithium batteries are a class of batteries with lithium metal or lithium alloy as negative electrode materials and use non -hydraulic solutions.Lithium batteries are small and light, and are more efficient, secure, and environmentally friendly compared to traditional lead -acid batteries.Very suitable for elderly and female friends.The disadvantage of lithium batteries is that the price is slightly higher.
Nickel-cadmium batteries
Nickel -cadmium battery weight is light weight and long life is its biggest advantage.Nickel -cadmium batteries can generally repeat more than 500 charging and discharge, which is more durable.The disadvantage is that the price is high, the capacity is low, the mileage of the battery life is short, and the nickel -cadmium battery has a memory effect. The battery power must be fully charged.
NiMH batteries
The energy of nickel -hydride batteries is higher than that of nickel -cadmium batteries, and the mileage is slightly longer.At the same time, it also overcomes the shortcomings of the memory effect of nickel -cadmium battery, and has recently declined with the growth of production.At present, some electric vehicles have begun to use nickel -metal hydride batteries.
How to buy electric vehicle batteries
First, pay attention to the battery capacity and voltage indicators
The battery is the main source of power for electric vehicles. Different capacity, power, and driving distance make the electric vehicle 2 to 3 times the price.Therefore, when buying, you must figure out how much and how many ampere are the electric vehicle batteries bought.Under normal circumstances, 48 ??volt and 20 -way electric vehicle battery is longer than the one -time driving after full charging of 36 volts and 10. Generally speaking, the greater the battery capacity and power, the higher the price.
Second, ask the warranty period and specific warranty of electric vehicles
Merchants generally promise the battery warranty for one year, but the "one year" that the merchant says is "one year": Generally refers to the new battery replacement of quality problems from the date of purchase.Old maintenance batteries are not responsible for the merchants after one year of use.Therefore, consumers must negotiate with the merchants specific warranty period and corresponding content when buying a battery car, and indicate on the warranty card to avoid consumer disputes.
Third, choose brand, service and word of mouth
Brand, service and word of mouth are the best way to promote electric vehicles.When purchasing consumers, not only should choose good quality electric vehicles, but also compare services and brands. Pay attention to whether the product has a after -sales service point in the region.When a failure, it can be solved in the shortest time.
How to maintain electric vehicle batteries
1. Dont change the charger casually, dont remove the speed limit of the controller
The chargers of each manufacturer generally have personalized needs. Do not change the charger at will when you are not sure.If the renewal mileage requires a long time, it must be equipped with multiple chargers for different places, and the charger that replenish the charging during the day uses another supplementary charger, and the original charger is used at night.
2. Protect the charger
The general instruction manual is about the instructions for protecting the charger.Many users do not have the habit of reading the instructions. They often think of finding a manual after problems. It is often too late, so it is necessary to read the manual first.
3. Charging every day
Even if your renewal ability is not long, you can use it for 2 to 3 days at once, but it is recommended that you charge it every day. This will make the battery be in a shallow cycle and the life of the battery will be extended.Some early use of mobile phone users thought that the battery was best used after the battery was basically used. This view is wrong. The memory benefits of lead -acid batteries are not so strong.
4. Charging in time
After the battery discharge, the sulfurization process began. From 12 hours, obvious vulcanization appeared.Charging in time can clear the disinvas that are not serious. If not charged in time, these vulcanized crystals will be accumulated to gradually form a large crystallization. Generally, the general charger is incompetent to these thick crystals.The life of the battery.
5. Regular deep discharge
The battery is regularly deeply discharged. It is also conducive to activating the battery and can slightly increase the capacity of the battery.The general method is to regularly discharge the battery at a time.The way to discharge completely is to ride the first lack of voltage protection under the normal load of a flat road surface.After completing the complete discharge, the battery is fully charged.It will feel that the battery capacity is increased.
6. Develop some good habits of power saving
Use taxi as much as possible.When the downhill, use early power off and taxi to decelerate as much as possible.Enter the glide in advance when you are about to encounter the traffic light, minimize the brakes.When starting, it is best to add riding to help, which can not only increase the startup speed, but also reduce the batterys power loss and life damage.
7. Pay attention to the charging environment
The best ambient temperature for charging is 25 ° C.At present, most chargers do not have an automatic control system that adapts to the environmental temperature, so most chargers are designed according to the ambient temperature at 25 ° C, so it is better to charge at 25 ° C.
8. Make full use of maintenance conditions
Many electric bicycles dealers can provide battery maintenance and maintenance services, and they should make full use of these services.Some brands of electric bicycles propose to repair batteries.For example: regular maintenance of the battery can reduce damage to the battery.
Can charge.
NiMH batteries
The energy of nickel -hydride batteries is higher than that of nickel -cadmium batteries, and the mileage is slightly longer.At the same time, it also overcomes the shortcomings of the memory effect of nickel -cadmium battery, and has recently declined with the growth of production.At present, some electric vehicles have begun to use nickel -metal hydride batteries.
