New energy vehicles
Do you need to heat your car in winter?How to charge? How to maintain it?
—New Energy Vehicle User Guide—
When using a car in winter, the first step when driving a traditional fuel vehicle is usually to warm up the car. The purpose is to allow the engine oil to fully lubricate the interior of the engine and slow down engine wear.
So,Do new energy vehicles that use electricity as their main power need to be heated in winter?? How to charge in winter?How to maintain it in winter?
Of course!
The temperature is low in winter, and the battery activity of new energy vehicles is relatively low in winter. Warming up the car in advance in a low-temperature environment can allow the power battery to reach the ideal operating temperature, so new energy vehicles also need to be properly heated. If the car is not warmed up,Will affect the cruising range, because driving directly and violently will lead to high power consumption, low speed, and reduced battery life. Under the same power consumption, a battery that has been fully heated by a hot car will run faster than a cold battery that has not been heated by a hot car.
How to warm up the car?
When a new energy vehicle is warmed up, it does not idle on the spot, butHow to drive at low speedTo achieve the purpose of warming up the car. When stationary, the battery does not work at all. Only when driving slowly can the coolant in the battery gradually heat up. Pay attention during this process.Do not accelerate or brake suddenly。
Make sure the gun tip is dry when charging in winter. Slow charging is recommended.
New energy vehicles are mainly divided into plug-in hybrid vehicles and pure electric vehicles. No matter which power mode is used, the charging tip should be dry and clean in winter. AC slow charging is more recommended for daily use, especially when using public charging piles outdoors.
Do not discharge deeply and charge regularly if left idle for a long time.
The battery is leaking, please charge it for a while before driving.
In winter, there may be a situation like this: the electric car still has 70% of the power the day before, but when you drive it after a night, you find that it has a "power leakage"!
In fact, this is not a "leakage", but a fault caused by "low temperature". When an electric vehicle is driving, the battery is in a state of continuous discharge. The battery will generate heat during discharge, so the battery itself is relatively hot and the battery voltage is relatively high. Therefore, you can see that the electric vehicle has a relatively large amount of remaining power.
However, after being parked all night on a low-temperature winter night, the battery has already cooled down and the voltage has dropped. At this time, the BMS will automatically adjust the displayed power and cruising range. This is the so-called "leakage".
Don’t use charging stations in rainy or snowy weather?
Autumn and winter are prone to rain and snow, and the air will become humid at this time. Many car owners are worried that the humidity of the air will affect the insulation. Here, the editor tells you: Car owners please rest assured that before the charging pile is connected to the car and charging is started, the charging pile itself is not charged. Therefore, when charging in rainy and snowy weather in autumn and winter, as long as the vehicle interface is not in the rain and the gun tip is dry, charging can be started normally.
1. Antifreeze is used, but the motor or electronically controlled cooling system fails and the motor is damaged; (antifreeze fails)
2. Vehicle lights dim in foggy weather in winter; (bulbs age)
3. The wipers are deformed or the windshield is frozen; (glass water is not suitable for low-temperature weather and freezes below zero)
4. Sudden current short circuit or even spontaneous combustion; (spontaneous combustion caused by dryness in winter, or damaged circuits)
5. Driving in rain or snow is slippery; (tire friction coefficient becomes lower at low temperatures and tire pressure is unstable)
Store your vehicle properly
In winter, if possible, try to park the vehicle in a garage, or take certain measures to keep it warm and antifreeze, such as covering it with a warm tarpaulin to protect battery activity and capacity.
Try to avoid slamming on the accelerator
When starting a vehicle, carrying people, or going uphill in winter, try to avoid slamming on the accelerator to accelerate. It will cause large current discharge. You should drive at a constant speed in winter to keep the battery healthy.
Don't turn the steering wheel hard
When driving on a slippery road, if you turn the steering wheel sharply, you will instantly lose steering control, and the vehicle will coast and cause an accident. Whenever you are driving on a slippery road, you should slow down and turn the steering wheel lightly.
Select point brake
When driving on icy and snowy roads in winter, if you directly step on the brakes, the vehicle will easily lose control. If you want to control the vehicle to the maximum extent while driving, you must perform continuous point braking, so that the braking effect is the best.
Safety is no small matter
For your safety and the safety of others
Please drive properly
Never take chances
