Immediately entered the first year of the new national standard, in order to meet the policy requirements, electric vehicles can not prevent. However, many friends are doubts, is it necessary to buy a lithium tram? Can you replace the lead-acid battery of your electric car to a lithium-ion battery? To this end, Xiaobian special connection consultation has many years of electric vehicle maintenance related experience, Li Master Li gives affirmative answers. 1, pay attention to the size.

The battery bin of the electric vehicle is just in line with the size of the lead-acid battery. If it is replaced with a lithium-ion battery, pay attention to the lithium ion battery volume. Otherwise, if the installation is too large, it is easy to cause small batteries to shake, reduce life.

2, charger match. Because lead-acid and lithium battery are different, the charger of the two batteries cannot be universal, be sure to select a lithium ion battery special charger. 3, the voltage is consistent.

If the lead-acid battery is replaced with a lithium-ion battery, it must also consider that its voltage must be maintained as the original lead-acid battery, but the capacity can be increased, and the battery life is longer. For the lead-acid battery. From the technical level, lead-acid electric vehicles are changed to a lithium-ion battery, but it is necessary to find professional electric vehicle maintenance personnel to conduct professional processing.

If private modifications, not only affect the performance of lithium-ion batteries, but even buried safety hazards. If the lithium ion battery is improper or what quality problems, it may burn the controller, which is also one of the reasons why it is not recommended. According to the relevant information, the number of office workers at the Beijing office worker in 2015 is about 19km, and the data is only a lot of data in 2017.

Take the author as an example, my top and trip to and from the commuteth is about 50km. If I ride a 60V20ah, the motor power is 800W, the motor vehicle is commuted, the speed is kept at 30km / h, then I can Consumption of a cycle charge and discharge. According to the 21st workdays of one month, add the long-term riding time of the weekend and holidays, and the circulation of the electric car is about 300 times in the year, and we introduce the lead-acid battery.

The service life is charged and discharged from 400 cycles, so in such a high-frequency cycle, a lead-acid battery life is up to a year and a half. Lithium-ion battery life: Lithium-ion battery usually we have contacted, as an example, a mobile phone is in use for 1-2 years, it is not as good as before, but few people will consider replacement within two years. Battery.
