How can new energy vehicles be summer summer summer

Today, new energy vehicles have become the first choice for many people to buy cars. New energy vehicles are different from traditional fuel vehicles when they are used. Especially for some novice drivers who have just been exposed to new energy vehicles, what should I pay attention to when driving and charging in a hot summer day? How to reduce the incidence of vehicle failure? The reporter interviewed Li Guangxin, a new energy vehicle expert of the School of Mechanical Engineering, Hebei University of Technology, and asked him to make some prompts for the owner of the new energy vehicle.

High temperature in summer affects the mileage

According to Li Guangxin, many people know that the mileage of new energy vehicles in winter will become shorter. But many people don't know that in high temperature weather, the battery life of new energy vehicles will become shorter. Because the temperature in summer is high, and the battery is in a hot state when the new energy vehicle is running, the two are superimposed, which will accelerate the consumption of electricity and then reduce the mileage of battery life. In addition, when driving in summer, drivers and some electronic auxiliary equipment such as air conditioning will also lead to a decline in mileage.

Car charging pay attention to these issues

Charging new energy vehicles in summer, the first choice of cool and backlight, such as underground garage. In addition, if there is conditions, try to choose slow charging, because the voltage and current during fast charge are relatively large, which will cause certain losses to the battery. Experts are particularly reminded that some citizens are convenient for pictures and choose to "fly wires" from home to charge the car. First of all, this charging method is illegal. In addition, these "flying wires" mostly use some ordinary wires, wiring boards, etc. After high temperature exposure, short -circuit and even caused by fire. Therefore, when charging new energy vehicles, you must choose a regular charging pile or charging station.

Be careful when the rainy season is coming to wading

The rainy season is approaching, and many car owners are worried that new energy vehicles will break in the event of wading. In fact, this is a misunderstanding. The battery of new energy vehicles is generally located at the bottom of the vehicle. The manufacturer will perform waterproof protection for it. The vehicle use manual will also clearly indicate the height of the wading. As long as the water -related location does not exceed the upper limit of the wading height, it will not affect the normal driving of the car. Essence However, if a plug -in hybrid new energy vehicle has an exhaust pipe, you need to pay attention when wading. In addition, the rainfall in summer is frequent, and it is not suitable for charging when it is raining. If the light rains can charging the charging pile at home, under this weather conditions, experts do not recommend using open -air public charging piles, because the degree of maintenance of public charging piles is different. The sealing interface of the charging gun may have problems. At this time, there is a certain safety hazard in charging.

The habit of using a car is related to the battery life

Experts introduced that people who buy new energy vehicles are very concerned about battery attenuation. At present, new energy vehicles produced in China mainly use two batteries, namely lithium iron phosphate batteries and ternary lithium batteries. From the perspective of battery attenuation, the ternary lithium battery is better than the lithium iron phosphate battery, but the safety of lithium iron phosphate batteries is higher than the ternary lithium battery. Normal new energy vehicle batteries will face the problem of battery attenuation, but there is no law to follow, because it is related to the driving habits and charging habits of the owner. If you want to slow the degree of battery attenuation, keep good driving habits, such as do not speed up suddenly, step on the brakes suddenly, and keep the power state as much as possible. Do not wait for the battery balance to call the police before charging.

If you can charge 50 degrees at a time before, you can only charge 45 degrees at a time at a time; or you can charge the electricity once every three days, and now it must be charged once every two days, indicating that the battery is attenuated. At present, the battery can only be replaced after decay. Although some car 4S store sales staff now say that the battery can be replaced for free for customers' new energy vehicles in the future, people must see the relevant standards and conditions for changing batteries when buying a car, or require car sales staff to include them in the car purchase contract Among them, disputes will occur when replacing batteries in the future.
