Now, electric vehicles have become a daily means of transportation for many people, not only affordable, but also easy to use. However, as a model that relies on electric power, its overall performance is greatly affected by batteries. Especially for electric vehicles equipped with 48-volt, 60-volt, and 72-volt batteries, the endurance of electric vehicles is also different, and charging is often different. Then let’s talk about these issues about electric vehicles.

How much electricity does an electric car need to be fully charged? How long does it take?

The battery life of an electric vehicle depends on the battery, so if you want to know the time and battery charge of the electric vehicle, you can know it as long as you find the specific capacity of the battery. Nowadays, the batteries used by electric vehicles on the market are relatively fixed. The most common ones are 48V, 60V and 72V lead-acid batteries. Of course, the battery does not need to be based on the voltage, but also on the battery capacity.

1. 48-volt electric car

According to experience, if the power of an electric car equipped with 48V12Ah lead-acid battery, if the battery is completely used up, it will take about 7 hours to fully charge normally. Of course, it can also be calculated using the formula, that is, the charging time of = battery capacity/charging current . If the current is 1.8A, the charging time is 12÷1.8=7, which means that the charging time is also about 7 hours. And so on, if it is a 48V20Ah lead-acid battery, it is often 20÷2.8≈7 when charging, which is about 7 hours.

In addition, how many kWh is required for full charge can be calculated, that is, the formula P=UI, so the power capacity of the 48V12Ah battery is 48*12=0.576Kwh, which means that 0.56 kWh is required for full charge. The power capacity of the 48V20Ah battery is 48*20=0.96Kwh, that is, 0.0.96 kWh.

2. 60 volt electric vehicle

60V electric vehicle can also be calculated through the above two formulas. The charging time of the 60V20Ah battery is 20÷1.8≈7h, and it takes 60*20=1.2Kwh, which is 1.2Kwh, which is 1.2Kwh; the charging time of the 60V32Ah battery is 32÷4.5≈7h, and the charging time of the 60V32Ah battery is 60*32=1.92Kwh, which is 1.92Kwh.

3. 72V electric car

Through the above calculations, a rule can be obtained. The battery charging time is basically determined and has little to do with the battery capacity. From this, it can also be calculated that the charging time of a 72V electric car is 6-8 hours. A 72V20Ah battery needs 1.44 degrees to fully charge, and a 72V32Ah battery needs about 2.3 degrees to fully charge. How far can

48 volt, 60 volt and 72 volt electric vehicles go?

has talked about the charging time and power consumption of various batteries above. In fact, more car owners are still concerned about the battery life of electric cars, so the battery life is still based on the commonly used battery specifications.

first of all, the 48V12Ah and 58V20Ah battery mentioned above, which is currently commonly used battery configurations for new national standard electric bicycles, with a range of about 30 kilometers and 50 kilometers respectively. If it is a lithium battery, the battery life will be slightly improved.

followed by 60V20Ah and 60V32Ah lead-acid battery , which is a common configuration of electric motorcycle on the market, with a range of about 50 kilometers and 100 kilometers respectively. This kind of electric car will basically not be equipped with lithium batteries, and even if it is available, it is very expensive and not cost-effective.

finally has 72V20Ah and 72V32Ah lead-acid battery , which is a regular configuration for power-on-operated motorcycles on the market. If it is an ordinary lead-acid battery , the range will be around 60 kilometers and 120 kilometers respectively. If it is an graphene battery , the range will be improved. For example, a 72V32Ah battery can reach a maximum range of 150 kilometers.

The battery life mentioned above is mostly data under the smooth operation of electric vehicles. If it is on an uneven road and is driving at high speed, the battery life will definitely not reach what I said. This also explains why many brand promotions can run hundreds of kilometers, but the car owners get it but there is a big gap between them. Which battery is more cost-effective and durable to replace an electric car with an electric car?

Of course, the quality of the battery depends not only on the battery voltage and capacity parameters, but also on the quality of the battery itself.For example, batteries are also divided into grades now. The bottom layer is ordinary lead-acid batteries, the slightly better ones are upgraded lead-acid batteries, the better ones are graphene lead-acid batteries, and the best ones are lithium batteries.

As for what kind of battery to replace with electric cars, I think it depends on the quality and the price. Only when the two are combined is a good battery. So for electric cars to replace batteries, I suggest that it is best to choose some upgraded lead-acid batteries for , such as the second generation of long-distance running kings that can in 1 day. The performance is slightly lower than lead-acid batteries, but the price is also lower. This battery is relatively cost-effective.

If the budget is enough, you can choose both graphene batteries and lithium batteries, but be careful. If the electric car is a lead-acid battery, it is best to replace the lead-acid battery, and vice versa.

talks about

The batteries of electric vehicles are generally not very high, and the battery required is not much, but the charging time is relatively long. However, the cost of using electric vehicles is relatively low, at least much lower than that of motorcycles. The driving of electric vehicles is also relatively simple, suitable for most people. If the battery you choose is of high quality, the service life will not be short.
