Is the price of 48V lithium battery electric vehicles high?
Generally, a single lithium battery cell is 4.2~4.0V. Therefore, the price of a 48V lithium battery u003d the price of a single lithium battery cell x (4.2~4.0v*nu003d48v) * m (m in parallel with the same lithium cell group) + the price of external protective battery materials. The price of 48V lithium battery is currently 2 times more expensive than that of lead-acid batteries, but its service life is 2-3 times that of lead-acid batteries. First of all, we use 48v12AH 18650 lithium battery to calculate, the capacity of a single 18650 lithium battery is 2000MAH, then the number of 18650 lithium batteries required is 12*6u003d72, and the price of a single 18650 lithium battery is about 5 or 6 yuan. , Including some labor and material costs for packaging PACK, the ex-factory price is basically around 500 to 600. Of course, the more expensive the lithium battery, the larger the capacity of the lithium battery, and the longer you can run. But this is all in general terms. First of all, you need to know how far you want to run? You can reverse the lithium battery capacity you need based on mileage. Here are two calculation methods that are extended and recommended. Netizens can also test it. 1. The lithium battery for electric vehicles is generally 48V20Ah. Assuming that its overcurrent is 10Ah, and the discharge of the battery during normal use is generally about 75% of the total power, so the continued driving timeu003d75%×20AH/10Au003d1.5 hoursu003d90 Minutes, and the electric energy releasedu003d48×20×75%u003d720W, the average speed should be between 20 horsepower~25 horsepower×1.5 hoursu003d30~37.5 kilometers. 2. How far can a 48V electric vehicle run on the road? Another convenient way to calculate the mileage is as follows: mileage u003d battery capacity u0026pide; (motor u0026pide; nominal voltage) × average speed per hour. How far do you want to go when riding a 48V electric bicycle with lithium batteries? You can first calculate the approximate capacity of the lithium battery used based on the above, and then consult and compare based on the battery capacity, and then you can understand how much the approximate 48V electric vehicle battery is suitable for.
