Electric vehicles are now many people are choosing short-distance travel transportation, now it has basically replaced the bicycle, is replacing the motorcycle, become the "king" of two-wheeled transportation, and the mainland, but also become a large country in the production, sales and ownership of electric vehicles.
Electric vehicle products are now very rich, in addition to different brands, there are various models, and electric vehicles have experienced decades of development, but also from the early endurance is generally 30 to 50 kilometers, can only be short-distance endurance, the development of now 100 kilometers endurance, even 200 kilometers, 300 kilometers of electric vehicles, are everything.
However, many people after buying a car, will feedback their own electric vehicle endurance, and the business advertised the endurance is far from the difference, many electric vehicles have a "virtual standard endurance" situation, then, how to buy an electric vehicle to know the real endurance, small experts today to share a calculation formula, before buying a car to do their own calculation, no longer afraid of being some "endurance" to fool.
How to calculate the real endurance of electric vehicles? Remember this formula
The endurance of electric vehicles mainly depends on the battery, and the main influencing factors are also the power of the motor, the control speed of the controller, therefore, we only need to grasp these 3 key elements, through the calculation formula, you can calculate the real endurance level of the electric vehicle, the calculation formula: battery voltage× battery capacity× speed÷ motor power.
Battery voltage: refers to the potential difference of the battery, the mainstream electric vehicle has 48 volts, 60 volts, 72 volts these three kinds of voltage, rare also 36 volts, 94 volts voltage, the greater the voltage, the higher the endurance.
Battery capacity: refers to the size of the battery can store electricity, the capacity specifications of the battery are more, lead-acid batteries are common 12AH, 20AH, 32AH, graphene batteries have 22AH, 38AH, etc., lithium batteries have 23AH, 32AH, 40AH, etc., the larger the capacity, the farthest the battery life.
Speed: The speed of electric vehicles is well understood, the maximum speed of electric bicycles is generally 25 km / h, the electric light motorcycle is 50 km / h, and the electric motorcycle is 70 km / h, the lower the speed, the better the endurance of the electric vehicle.
Motor power: This is the key factor affecting the power, but it is also related to endurance, because the greater the power used, the higher the power consumption, the common power is 400W, 800W, 1200W, etc., with the configuration, the smaller the power, the higher the endurance of the electric vehicle.
The above comprehensively introduces the key parameters that affect the endurance, then, the small connoisseur will give 2 examples, together to calculate the real endurance level of the electric vehicle of the 2 configurations.
1, suppose the purchase of an electric bicycle, its voltage is 48 volts, capacity 20AH, speed of 25 km / h, motor power of 400W, by calculating the real endurance = 48× 20× 25÷ 400 = 60 km.
2, suppose the purchase of an electric motorcycle, its voltage is 72 volts, the capacity is 32AH, the speed is 50 km / child, the motor power is 1000W, by calculating the real endurance = 72×32×50÷ 1000 = 115.2 km.
Little Connoisseur Summary:
The above calculation formula, can well calculate the real endurance of the electric vehicle, of course, the actual measured endurance, but also related to road conditions, temperature, how long the battery is used, etc., although the real endurance is not equal to the actual measured endurance, but the real endurance can debunk some businesses, random landmark list endurance, the battery is only 32AH, also known to be able to run 200 kilometers, we just need to remember that the actual endurance is lower than or equal to the real endurance derived from the above calculation formula, if the publicity endurance is far greater than the real endurance, then, there is a "virtual standard endurance." "Behavior, don't be fooled by the endurance said by the merchant.
I hope the above content can help you, so what electric vehicles have you encountered with false endurance? We also welcome comments and exchanges.
