Ten cold electric car charging remember these ten tips, will make your car run 10 kilometers more!
The weather has suddenly turned cold these past two days, and Xiaoxue's solar term is coming. It ’s cold, which brings inconvenience to our travel. What ’s more embarrassing is that our battery car is charged with the same electricity, and it has not run farther than before. This article introduces 10 methods and techniques for charging the battery car when it is cold. Let you Run 10 kilometers more on one charge! All dry goods! Very practical, it is recommended to collect.
1. To charge indoors, extend the time by 1-2 hours
In winter, when the weather gets colder, our electric bicycles should be charged indoors, and the charging time should be longer than that in summer. After the charger turns on, it can be recharged for 1-2 hours, but it cannot be charged for a long time.
2. Charge frequently, do not wait for the power to run out before recharging
When the weather gets cold, remember to recharge every day, don't let the battery go hungry, otherwise it will affect the battery life.
3. Charge the electric car in time when it is not less than 30%
When it's cold, the battery of the electric car should not be less than 30%, and it should be charged in time. If the charge is less than 25%, it will cause damage to the battery. That is, when the battery power is reduced to about 60-70%, it can be charged, because the battery's use process is also the process of battery vulcanization. When the battery is severely vulcanized to a certain extent, it means that the life is over. If the power is used up, Charging starts only at the next 10%, which means that 90% of the battery is used and participated in the vulcanization process, while the opposite one usually uses the remaining 70% of the electricity to start charging, indicating that only 30% of his battery is involved in vulcanization The rest is still in a brand-new state, so it will naturally take much longer to cycle down. This is the reason for the frequent charging in winter.
4. Cooling battery material activity is reduced, capacity is reduced
When the battery of an electric vehicle is at 25 ° C, the material activity in the battery is optimal, and the battery capacity can also be maximized. When the temperature drops below 10 ℃, the electricity stored in lead-acid batteries will be reduced by 20% -30%. When the temperature drops below 0 ° C, the stored electricity will be reduced by 30% -50% or even more, because the active substance contained in the battery, the temperature drops, the active substance is not decomposed sufficiently, and the electricity is reduced, which is normal.
5. Pay attention to the power at any time, try not to use smart fast charging
The fast charging station is a charging device that allows the electric vehicle battery to charge a certain amount of power in a short time through high-current charging. Most fast charging stations on the market use high-voltage high-current pulse charging, which will cause damage to the battery. Always pay attention to the power of electric vehicles and charge them in time. If you eat too quickly at one time, the "stomach" will be uncomfortable.
6. When starting uphill, use artificial assistance or slow acceleration
When the electric car starts and when going uphill in winter, if there is a pedal, try to use the pedal as a boost, and accelerate slowly and evenly without the pedal. The battery may be "strained". Don't overspeed and overload, maintain low-speed and uniform driving habits. The so-called low speed is to keep below 25 kilometers per hour, because too high speed requires more power to support, you can imagine how violent the reaction inside the battery will be, and the uniform speed is very important, rapid start and rapid braking will make the battery The voltage rises and falls greatly, which affects the lifespan, so as far as possible, usually start slowly and brake slowly to protect the battery.
7. The battery life is significantly reduced to be detected
When it is found that the power of the electric car is obviously low, no other reason can be found. It is best to take the car to an electric car shop or repair shop for testing to see if there is a battery problem.
8. The car is not used for a long time, and it is charged once a month
If your electric vehicle is not used for a long time, pay attention to recharging the battery once a month to avoid battery sulfidation and damage to the battery.
9. Use qualified chargers from regular manufacturers, pay attention to charging safety
Purchase qualified chargers from regular manufacturers, and ensure that the battery is within the validity period. Overcharged or inferior chargers will adversely affect the battery and even cause fire. At the same time, there should be no debris beside the charging, especially flammable items, to ensure the safety of charging.
10. It is normal for the battery power to drop, do not rush to replace the battery
In winter, the battery capacity of a battery car becomes smaller, and it is normal for not to ride for long. When the weather is warm, the electric car will "automatically" recover. When the temperature is lower than 0 ℃, the battery power will drop by 50%. If the temperature is below -10 ℃, the battery power will not even have 30% capacity, so it is normal for the battery power of electric vehicles to drop in winter. Do not rush to replace the battery.
[Summary] Remember the above ten tips to make your electric car safe and worry-free in winter. If you have done it, the cold weather can also keep your electric car battery in good fighting condition and let your car run more. ten kilometers.
