With the continuous improvement of battery technology, electric vehicles generally use lead-acid batteries. Nowadays, many electric vehicle batteries use batteries. So, which one is better to choose between lead-acid batteries and lithium batteries.
The advantage of lithium batteries is that they are lighter and smaller. The advantage of lead-acid batteries is that they are inexpensive and stable.
In addition, I think choosing an electric vehicle is not only related to the battery, but also to the brand and model, and then to see if lithium and lead-acid batteries can be used, so there is no need to worry about the battery. We recommend the Green Source electric vehicle here
The development of household electric vehicles is still very fast, mainly with the support of the government. On the one hand, it is for environmental protection, and on the other hand, it is for bypassing and overtaking, breaking free from the monopoly of the foreign automotive industry.
The biggest limitation of the development of electric vehicles lies in the advancement of battery technology, including energy density, lifespan, and charging speed.
The energy density of batteries is directly related to the range of electric vehicles. The energy density of lead-acid batteries is approximately between 40-50Wh/kg, while lithium iron phosphate batteries can reach 150Wh/kg, let alone ternary batteries reaching 300Wh/kg. So lead-acid batteries have limited use in the field of electric vehicles, except for their application in low-speed electric vehicles, mainly because low-speed electric vehicles do not have high requirements for range.
However, compared to the range of fuel vehicles, the energy density of the battery needs to reach at least 500Wh/kg, which is a major difficulty in improving battery technology and requires a long way to go.
The lifespan is easy to understand. Fuel vehicles can last for decades, while electric vehicles may require battery replacement within a few years due to varying battery quality. Given the high cost of batteries, it is important to choose a reliable battery manufacturer.
It can supply power to fuel trucks within a few minutes, and the fastest battery charging speed is about ten minutes. Currently, only lithium titanate batteries can achieve this goal. The cost is high price and low energy density Fast charging of other types of batteries usually takes one or two hours, while slow charging takes seven or eight hours. In addition, there are also issues such as inconvenient charging due to a lack of sufficient charging infrastructure.
Generally speaking, the development of electric vehicles depends on the advancement of battery technology (which may adopt the hydrogen energy route in the future). In fact, current electric vehicles can to some extent meet people's needs. For example, the electrification of urban buses and short distance logistics vehicles. For family passenger cars, it is not necessary to drive three to four hundred kilometers every day. Charging before bedtime (like a phone), electricity is much cheaper than gasoline!
Lead acid batteries are usually low-cost and cost-effective. The specific choice is based on the individual's choice of which type of battery to bring with the electric bicycle.
