After the winter, many online hailing drivers of
Used Car felt that the battery life of the vehicles was lower than before, and the batteries did not seem to be particularly durable. Therefore, someone asked the editor in the background that it was not something wrong with his car. Otherwise, there are many factors that affect the continuous voyage and charging time of
Used Electric Car in winter.
Most of the power batteries currently on the market are lithium batteries. For lithium batteries, low temperature will affect the activity of the positive and negative electrode materials of the battery, the internal resistance of the battery, and the charge and discharge voltage of the battery. In other words, the lower the temperature, the lower the activity of the electrode material, the less the lithium ions in the electrolyte move, and the higher the energy driving their movement. In this case, the appearance is that the battery capacity is low. up. However, this reduction in capacity is temporary, and it can return to normal when the temperature rises and the discharge conditions improve.
2. Related to driving habits
When driving in winter, try to drive at a constant speed to maintain the health of the battery. Especially when starting or going uphill with people, it is recommended that drivers try to avoid slamming on the accelerator, which will cause high current discharge. Moreover, if the brake utilization rate is too high, a large part of the energy will be wasted by braking.
For the Used
Electric Car with energy recovery function, the higher the energy recovery function is set, the stronger the deceleration effect of the vehicle. The decelerating effect causes the tires to slip.
At the same time, Used Electric Car should also avoid turning on too many vehicle electrical equipment in an unnecessary state for a long time, such as: audio, lighting, etc., so as not to cause low-voltage battery power loss.
3. Air conditioning consumes a lot of energy in winter
Different from
fuel vehicles, which rely on engine coolant for heating, Used Car need to be heated by electric heating wires, and the power is not small, generally around 5KW, which is equivalent to turning on the air conditioner for an hour. Consume about 10% electricity. Therefore, turning on the air conditioner is also one of the factors that lead to the decline in cruising range.
The editor suggests that you can adjust the air conditioner to a constant temperature of 25-26°C when using the vehicle, which is not only comfortable but also can greatly reduce the energy consumption of the air conditioner to extend the driving mileage.
4. The filling time is related to the temperature
The charging process is the process of electrons returning from the positive pole to the negative pole. Similarly, the lower the temperature, the slower the electrons will travel from the positive pole to the negative pole.
Everyone thinks that charging takes longer in winter because the temperature is lower. In order to ensure the normal use of the battery, it is necessary to heat the battery cells while charging, which is equivalent to increasing the time for warming up the battery during charging. So it shows that the charging time becomes longer.
If conditions permit, drivers can adopt the mode of charging as they use, and charge the vehicle immediately after use, because the battery temperature is relatively high at this time, which can effectively increase the charging rate. In addition, when charging, you can choose a warm environment, such as indoors or an underground garage to charge, which can also improve the charging efficiency.
Therefore, in winter, drivers should not worry too much about the drop in battery life, as long as they maintain good driving habits, control the temperature inside the car, and drive normally.
