When replacing a new battery or trading in the old one, many electric vehicle users will encounter such a problem, that is, to buy an electric vehicle battery, is it better to buy an electric vehicle battery, is it better to be bigger Ah, or the bigger is V, which is more cost-effective?
1. Endurance
First of all, from the perspective of battery life, we compare 60V32Ah batteries with 72V20Ah batteries, and 48V32Ah with 60V20Ah batteries. Among them, when the vehicle is equipped with a 60V32Ah battery, the motor is 600W-1000W, and the normal battery life can reach more than 100 kilometers, and if the motor remains unchanged, the optional 72V20Ah battery is selected, and the normal battery life is only 70-80 kilometers. When the vehicle is equipped with a 48V32Ah battery, the motor is 350-400W, and the normal range is generally about 100 kilometers, and if the motor remains the same, it is matched with a 60V20Ah battery, and the normal range is about 60-80 kilometers. Through comparison, we can all find that the larger the Ah, the longer the battery life is generally longer, and the more advantageous.
2. Durability
Secondly, from the perspective of durability, 60V32Ah batteries and 72V20Ah batteries, 48V32Ah and 60V20Ah batteries are also used as examples. Among them, if the optional is 60V32Ah, 48V32Ah battery, its battery life is more than 100 kilometers, riding about 15 kilometers a day, it is basically able to do 5-7 days for a charge, and if the optional is 72V20Ah battery, 60V20Ah battery, then the overall battery life is only 70-80 kilometers, normal 3-5 days need to be charged. This means that the 72V20Ah and 60V20Ah batteries age faster, and their durability is not as good as that of 60V32Ah and 48V32Ah batteries.
3. Price
Finally, and the price that everyone is most concerned about, also take 60V32Ah batteries and 72V20Ah batteries, 48V32Ah and 60V20Ah batteries as examples. Among them, the direct purchase price of 60V32Ah battery is about 1200 yuan, and the direct purchase price of 72V20Ah battery is about 900 yuan, which shows that 60V32Ah battery will be about 300 yuan higher than 72V20Ah battery. The direct purchase price of 48V32Ah battery is about 950 yuan, while the direct purchase price of 60V20Ah battery is about 700 yuan, and the difference is about 250 yuan. This shows that the larger the Ah, the higher the price, but the normal difference is about 250-300 yuan, which is generally acceptable.
Therefore, from the perspective of battery life, durability, and price, the larger the battery you choose, the better it will be, and its overall cost performance will be higher.
