The 48v24ah lithium battery can travel about 65 kilometers.
There are 48 V 24 Ah electric vehicles on the market equipped with 350 to 600 W motors. Suppose the motor power is 400 W and the average speed is 25 km/h. mileage, the average mileage of this electric vehicle. The current is motor power/voltage = 400 W/48 V = 8.3 A. The theoretical driving time of the electric vehicle is then battery capacity/average current=24ah/8.3a=2.89h.
In this way we can conclude that the real range of the electric vehicle is the average speed * theoretical driving time = 25 km/h * 2.89 h = 72.25 km. But this is only a theoretical autonomy. Actual range depends on road conditions, driving habits, lift, etc. There are some differences between the actual autonomy and the theoretical autonomy of the different models. Next, the electric vehicle 48v24ah can actually travel about 65 kilometers (data is for reference only).
Note:
Electric vehicles generally do not use all the energy before recharging, but charge when there is not much left of energy, a single charge is therefore sufficient. not enough. It consumes less than 1.2096 kilowatt hours of electricity. It is recommended to charge when there is more than 20% of the remaining power. Do not allow the electric vehicle to be charged multiple times while losing power.
Don't brake too many times when driving on the road, otherwise it will consume energy. In addition, when charging, you need to plug in the electric vehicle or battery end first, and then connect the power supply. .
Everyone knows that, unlike traditional fuel vehicles, the pure electric vehicles currently being developed arepowered by power batteries, which are then combined with electric motors to propel the vehicles. In the current pure electric vehicle market, power batteries are mainly ternary lithium batteries, and some models use lithium iron phosphate batteries. However, with the continuous improvement of battery technology, the cruising range provided by lithium iron phosphate batteries is also higher and higher. So, is it possible for lithium iron phosphate batteries to achieve a cruising range of 600 kilometers? Wenqing believes that there is still some possibility.
After several years of continuous development, power battery technology has also made great progress. For example, BYD's blade battery has improved the volume-specific energy density of lithium iron phosphate batteries to a certain extent. DuringAt the 100-person electric vehicle conference in China, BYD *** chairman said that the blade batteries will be mass-produced at the Chongqing factory. The so-called blade battery is actually a long battery cell solution, which is a technology that uses flat and long battery cells to further improve the efficiency of battery integration. According to BYD's official information, BYD's first pure electric vehicle equipped with blade batteries, the BYD Han, can even achieve a range of about 600 kilometers, so it is possible that the lithium iron phosphate battery has a range of 600 kilometers.
In fact, in addition to BYD's continuous efforts to improve the energy density of power batteries, another battery company, CATL, is also making continuous efforts. From the Frankfurt International Auto Show in Germany, CATL launched the development platformof highly integrated power batteries CTP.la tour. This technology eliminates the battery module assembly process, increases the utilization rate by about 15-20%, and increases the energy density of the battery by about 10-15%, which can also increase the battery life. battery life.
Summary: With the continuous development of technology, the energy density of power batteries is also increasing, which also means that the endurance performance of pure electric vehicles is increased. For car owners, it can improve the convenience of car use. I wonder what everyone is thinking?
