How many kilometers can you run? Related to the following conditions: I: Speed, car weight, load, etc. have a relationship. If you have a pre-lead-acid battery, the same capacity lithium-ion battery is almost the same.

Ambient temperature: When the ambient temperature is lowered, the battery use time will be shortened accordingly, according to relevant empirical calculations, the room temperature decreases by 1 ° C, the battery capacity will fall nearly 1%, so the electric vehicle battery is short. Discharge depth: The depth of discharge is often the extent of battery use in electric vehicle riding. The deeper the depth of the discharge, the shorter battery life.

Simply, after the battery is completed at one time, the longer the use of electric cars, the greater the depth of the battery. Pavement Traffic Problem: For the above data, it is basically in the flat road. If the slope is more, the running distance will decline.

Load weight, actual situation such as frequent braking start. Electric vehicle battery charging time: electric vehicle battery charging method is important, improper operation will damage battery. ● Electric vehicle tire pressure on the mileage of the mileage tire pressure is the air pressure inside the tire.

Generally, the tires produced by the regular manufacturers are marked with the most suitable tire pressure range. What is the impact of the tire pressure on the battery life? For a simple example, ride a bicycle on the way, suddenly feel that the car is particularly laborious, most people who often ride bicycles will realize that the car is not angry. In the case of the same case, the electric vehicle will bring a greater friction resistance to the electric car motor in the case of insufficient tire pressure.

In the same driver, the low pressure will double the electric vehicle power consumption. ● Impact of the front and rear wheel brake on the mileage. In the case of the electric vehicle, the brakes are not in the dark or there is fault inside the brakes, which will affect the overall battery life of the electric vehicle.

Many car novices have the same time when driving, so that the brake pads are severely worn, and serious will cause self ignition. Where is these wear and spontaneous heat? Naturally, the car's engine is blown to the brake pad and the wheel friction when driving the tire. In this way, if the vehicle does not fail, the fuel consumption will increase significantly.

The same reason, if there is a failure of the brakes of electric vehicles, it will also increase the power of the motor, resulting in the continuous current discharge of electric vehicle batteries. In this way, the life of the life is inevitable. ● Influence of brake power down on continuation mileage.

The initial design of the initial design of the electric vehicle's brake power down system is also this, ie the brakes, the electric car controller stops supplying power to the motor, so that both the battery and no motor. The truth is the same as the situation above, put it in electric cars, which is the large current discharge, which will affect the battery's total battery life. ● The impact of the charger on the mileage here is important analysis that the charger voltage is low on the battery.

The battery is dissatisfied, and naturally affects the battery life of electric vehicles. ● Effect of electric vehicle battery unbalance on continuation mileage. In the problem of battery life caused by the battery, a single battery has a large number of.

Single battery will affect the voltage of the entire set of batteries, so there is a set of failure or backward in the four batteries. The first case is very good, and after the load is loaded, the broken battery is no voltage. In the second case, if there is only two single-generation shorts of internal, then the voltage detected after the load is generally 10V, which seems to be no problem, but in fact, through the professional discharge equipment The charge and discharge is very clear.

The battery voltage of single short circuit is high, but 5a discharge time will generally not exceed 30 minutes, that is, it has been invalid. ● Impact of motor use time and motor type on continuation mileage. If it is an electric vehicle that is often overloaded or speeded, the electric machine will be degauss or aging as the use time is increased, which affects the energy conversion of the motor.

New power consumption, but torque and speed reduce. Viewing the motor type is important to determine if the motor is a brush motor. The brush motor is maintained after a period of use.

If not maintenance, after a period of time, the carbon brush wear, commutation wear or motor internal carbon powder accumulation will cause a significant increase in motor power consumption, thereby affecting the torque and endless mileage of the motor. All in all, there is a lot of factors affecting the mileage of electric vehicles. If there is no need for electric vehicle maintenance related experience, there is not enough battery testing equipment, then electric car batteries that can be used will also be determined as damaged batteries, some have been damaged.

Battery is identified as a battery without problem. The cost of the battery is generally three hundred to one thousand, but even so, if it is frequently replaced, it will bring a small test to the family expenditure. Extend battery life, 2 points to remember: 1 These will affect the life of the battery, resulting in shortening its use.

2, regular maintenance regularly check the outer casing of the electric car battery to see if there are deformation, damage, scratches, and other problems. If there is, it is necessary to go to the maintenance point for repair, and it is thoroughly detected. If it finds that the terminals are found Corrosion phenomenon, it is also handled in time to avoid leakage.
