Lithium battery is one of the latest new batteries developed with low environmental pollution that will gradually replace lead-acid batteries.
Compared with lead-acid batteries, lithium batteries have a relatively large electrical energy capacity, and compared with batteries of the same capacity in terms of volume and weight, lithium batteries have a very obvious advantage.
Currently, lithium-ion batteries have complex processes and high manufacturing costs due to cost. Therefore, lithium-ion batteries of the same capacity are much more expensive than lead-acid batteries.
Nowadays, lithium batteries are easier to use than lead-acid batteries, and in terms of battery performance degradation due to repeated charging, lithium batteries also have advantages obvious, which are fundamentally incomparable to batlead ries.
The number of kilometers you can travel depends mainly on the power of your engine and the amperage capacity of the battery.
The larger capacity battery can drive further.
In practice, a new lead-acid battery with a capacity of 12 Ah can travel around 25 kilometers when fully charged; a lithium battery can travel about 30 kilometers (road conditions have few traffic lights and (these are flat cement kilometers or new asphalt roads).
However, as a reminder, it It is better not to use the lithium battery until there is no more power. This will cause charging problems and also damage the battery if the battery capacity is very low. do not ride for a long distance Unlike lead-acid batteries, lithium batteries have a slow energy release process.If you drive too far, the capacity will suddenly drop, and the current and voltage will all drop instantly, and you will. face a situation where the bike rolls over you.
How far can a 48 V8 Ah lithium battery run?
The difference in battery life is 10 20 kilometers
First, let's look at 48V electric vehicles, there are three main battery models, namely 48V12Ah, 48V20Ah and 48V32Ah. The motor can be equipped with a power of 350W and 400W. This type of vehicle generally belongs to the new national standard electric vehicle. , and the speed of his vehicle is generally around 25 km/h. Taking 48V12Ah battery and 350W motor as an example, the average current at constant speed is 7.3A (motor power/voltage), the theoretical driving time is 1.6h (battery capacity/average current at uniform speed), and thethe theoretical range can reach 40 kilometers (driving time *speed). If combined with a 400 W motor, the theoretical battery life is 35 kilometers. On average, the battery range is around 37 kilometers.
Similarly, we can know that the theoretical battery life of a 48V20Ah electric vehicle is about 65 kilometers, while the theoretical battery life of an electric vehicle 48V32Ah is 103 kilometers.
Second, let's look at 60V electric vehicles. There are two main batteries, 60V20Ah and 60V32Ah. The motor can be equipped with a power of 600W or 800W, and its speed is generally around 45km/h. Taking as an example a 60V20Ah battery and a 600W motor, by calculation we can know that the theoretical lifespan of the vehicle battery is 90 kilometers and if it is equipped with an 800W motor, the lifespan of theoretical battery lifet of 60 kilometers; On average, battery life is around 75 kilometers. Likewise, we know that the theoretical range of a 60V32Ah electric vehicle is around 125 kilometers.
Through the above comparison, we can see that the speed difference between 48V electric vehicles and 60V electric vehicles is about 20 km/h. In terms of battery life, the difference in battery life between 48V20Ah electric vehicles and 60V20Ah electric vehicles is about 10 kilometers, while the difference in battery life between vehicles 48V32Ah electric vehicles and 60V32Ah electric vehicles is about 20 kilometers. From this we can know that for the same capacity, the difference in range between 48 V electric vehicles and 60 V electric vehicles is approximately 10 to 20 kilometers.
Of course, the above data is calculated intheoretical conditions. There may be deviations from the actual situation. For example, different vehicle charging and road conditions will also affect vehicle battery life. Why do you say that? The greater the vehicle's charging capacity, the shorter the battery life; and the milder the road conditions, the longer the vehicle's battery life. In addition, if the battery capacity is different, the difference in battery life will be greater, such as 48V12Ah electric vehicle and 60V20Ah electric vehicle.
The 48v8ah lithium battery can travel 25 kilometers. The rated voltage of the 48v8a lithium battery is 48v and the rated current is 8a. When the 48V8a lithium battery is a new battery just left the factory, it can travel up to about 40 kilometers. The battery hasA 48v8a lithium battery is used for one year, due to the aging of the lithium battery, the energy storage of the lithium battery decreases. At present, the lithium battery can only operate for 20 to 30 kilometers.
48v8ah lithium battery characteristics
The lifespan of the 48v lithium battery is related to the capacity of the battery itself and to the engine power of the electric vehicle Now the market conforms to national standards. Electric bicycles generally use 48V, 12Ah lithium batteries and 350W motors. With the development of battery technology, their theoretical endurance can reach 50km. Actual endurance is always determined by the weight of the rider. the weight of the vehicle.
If you pay attention to battery life, you can buy a 48V 20Ah battery, which can reach 70km. If you need lifeesse, you can also buy an electric motorcycle. Electric motorcycle batteries are generally 72 V 22 Ah. can reach 90 km. 48V lithium batteries are the first type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution.
