As an important power source for electric vehicles, the cost of batteries is also the highest among all components of electric vehicles. Whether it is an electric two-wheeler, three-wheeler, or four-wheeler, the cost of replacing a set of batteries is more expensive than other components. But in a longitudinal comparison, the battery price of an electric two-wheeler is lower than that of an electric tricycle, and the price of an electric tricycle is lower than that of a low-speed four-wheeler.
First, the battery capacity is different
The same 72V battery, the price of a set of batteries for electric two-wheelers is 650-1500 yuan. The price of a set of batteries for an electric tricycle is 1500-3000 yuan, and the battery price for an electric four-wheeled vehicle is 3000-8000 yuan!
Although electric two-wheeled, three-wheeled, and four-wheeled vehicles are all lead-acid batteries with the same voltage, electric two-wheelers mainly use small-capacity batteries of 12ah, 20ah, and 30ah. Electric three-wheeled and four-wheeled vehicles use 45ah, 58ah, 80ah, 100ah, and 120ah ultra-large capacity batteries. Large-capacity batteries cost more than small-capacity batteries, which is easy to understand!
Second, the performance of the battery is different
Electric bicycles and motorcycles use DZM batteries (maintenance-free batteries for electric mopeds), which are small in size and light in weight.
D stands for electric, Z stands for power assist, and M stands for maintenance-free.
In addition, electric tricycles and four-wheeled vehicles use EVF batteries (valve-regulated lead-acid batteries), EV refers to the special use of electric vehicles, F is valve-controlled, this type of battery has large volume, high energy density, good charging and discharging performance, and at the same time acid-proof, longer service life!
3. The warranty period of the two is different
The warranty period of the DZM battery of electric two-wheeled vehicle is 8 months for replacement, 8-12 months for turnover battery, and 12-15 months for maintenance battery. EVF batteries for electric three-wheelers and four-wheelers are replaced every 6 months and maintenance batteries are replaced every 12 months. No warranty for more than 12 months. It seems that the warranty policy of electric two-wheelers is better!
Fourth, lithium batteries for electric three-wheeled and four-wheeled vehicles began to be popularized
Lithium batteries for electric three-wheeled and four-wheeled vehicles have gradually become popular, and the price of lithium batteries is better than that of lead-acid batteries, which can not only reduce the weight of the vehicle. Considering the cost, most of the electric two-wheelers still use lead-acid batteries. Therefore, the price difference between the two is huge!
Summary:
Many electric two-wheeled, three-wheeled, and four-wheeled vehicles are marked with 72V and 60V, in fact, the battery itself is still very different, and there are differences in capacity, performance, warranty, and capacity!
