Slow charging (conventional charging, on-board charging) is suitable for on-board chargers and family wall-mounted charging piles, whose current and power are relatively small, and the general charging time takes 6-8 hours. Fast charging (ground charging, emergency charging) includes two forms of charging station and mobile trolley, mainly through the non-on-board charger using high current to directly charge the battery, so that the battery can be charged to about 80% of the electricity in a short time, generally 1 hour can be fully charged.
The impact of fast and slow charging of new energy vehicles on the battery is: the charging current of fast charging is large, so it is chargedThe electricity time is much shorter; The charging current of slow charge is small, so the charging time is long. Slow charge adopts constant current charging mode, and automatically turns to trickle charge after full; The fast charge generally uses degree pulse high current charging, and the polarization reaction in this process will cause the battery temperature to rise rapidly, which will have some impact on the battery life.
Hybrid vehicles have a variety of charging methods, if you are a gas-electric hybrid vehicle, not only can not support fast charging, also can not be external charging, only plug-in hybrid vehicles support external charging, if the battery is relatively large, it can be fastIt's charged.
Slow charge mode: The low current is used to charge the power battery for the vehicle, and the charging time is generally more than 3 hours. The advantage is that the charging current and power are low, and the impact on the battery life of electric vehicles and the impact on the grid are small; The disadvantage is that the charging time of electric vehicles is longer, and it is difficult to meet the emergency demand for electric energy supplement.
BMW hybrid new energy vehicle charging time to more than 3 hours, it has a fast charge: portable charging gun. Just connect to the household 220V 16A three-eye socket to charge the electric car, but the charging speed is slow. Portable charging gun on the InternetBattery loss connected to run high speed can charge into the electricity? '> The car battery is connected to the loss of electricity running high speed can be charged?
1, battery loss can be charged by running high speed high-speed wireless charging of tram , but need to pay attention to some details. First high-speed wireless charging , the car has been using electricity high-speed wireless charging , and often brake power consumption, the generator is always generating electricity, but the battery voltage is high and low, the generator output voltage rises with the speedHigh. Therefore, in the charging process, it is necessary to use 1500 RPM charging for a period of time (about 1 hour later), and the speed should be increased to 1900 RPM recharging, about 1 hour later, basically full (90%).
2, battery loss can be charged by running at high speed, but it is necessary to pay attention to the following points high-speed wireless charging of tram : The car in the process of driving, the electrical equipment has been used, while the brake will consume electricity, so the generator has been generating electricity. However, the voltage of the battery will vary, and the output voltage of the generator will rise with the increase of the speedHigh.
3, battery loss can be charged through high-speed driving high-speed wireless charging of tram ? High-speed driving can theoretically charge the battery, but you need to pay attention to details when operating. First, the vehicle continues to consume electricity at high speeds, and frequent braking significantly increases energy consumption. The battery voltage is not constant, and the output voltage of the generator increases as the speed increases. For most vehicles, a smooth start requires half of the battery power, that is, the battery voltage is about 14V.
4. Yes. It could take more than an hour. Slow charge (conventional charge, on-board charge)Suitable for car charger and family wall-mounted charging pile, its current and power is relatively small, the general charging time takes 6-8 hours.
5, battery loss can be charged by running high speed. When the car uses electricity, often braking will consume a lot of electricity, the generator will always generate electricity, but the voltage of the battery will vary, and the output voltage of the generator will increase with the increase in speed. If you want to successfully start the car, the battery needs to have half of the electricity (corresponding to the battery voltage of about 14V), when the engine speed reaches about 1200 RPM, you can charge the battery 14V.
6, in general, although high-speed driving can charge the battery, but the efficiency is not high, and speed control is crucial. If your battery power is OK, you can try this method, but if the power is low, it is recommended to use a professional charging device to avoid damage to the battery. In addition, in order to protect the battery, frequent braking should be minimized, which can reduce power consumption, thereby extending the service life of the battery.
Adjust the driving mode in time and control the throttle at the minimum to reduceLess power consumption. Turn off air conditioning and other power-consuming functions, such as listening to music, water heater, etc. Move the vehicle to the side of the road as much as possible, place a tripod to prevent the vehicle from sliding, and if the situation permits, you can order a limo model and escort the car to a service station for repair.
Electric vehicles on the highway out of power, you can take the following measures: Look for charging piles: Although the current highway is basically equipped with charging piles, but the number is limited and often malfunction. Therefore, before traveling, be sure to find out whether the high-speed service area of the way has charging piles, and plan when to charge. Contact trailer: If yesNo power broke down, can only call a trailer to tow the vehicle to the nearest charging pile.
If possible, find a ride-along service, such as contacting a friendly vehicle to take your tram to the nearest service area. Emergency help, in special cases, call the high-speed patrol vehicle assistance hotline, they usually have a reception station in the service area, will provide assistance, the vehicle safely transferred to the maintenance area. Remember, prevention is always the best policy.
Solar charging Solar charging is currently a more common way of charging, many cars are smallThe dolls are charged by solar energy to shake their heads, so this technology is expected to be applied to car driving in the future, to ensure that the car can be charged while driving under certain light. However, in the event of adverse weather conditions, the charging and driving problems of the vehicle may be hindered.
When the car is driving on the road equipped with wireless charging coils, through the principle of electromagnetic induction, electrical energy can be transmitted wirelessly to the car battery, so as to achieve the effect of charging while driving. However, this scheme faces problems such as high construction costs and difficult maintenance. Solar charging technology Solar charging technology is an environmental protectionAnd renewable energy use.
Solar charging At present, solar charging is a common way of charging. Many car dolls rely on solar energy to charge their heads. Therefore, this technology is expected to be applied to car driving in the future to ensure that the car can be charged when driving under a certain amount of light. However, if you encounter bad weather conditions, it may hinder the charging and driving problems of the vehicle.
As for the electromagnetic wireless charging scheme, aluminum can also be used to replace copper as raw materials to a certain extent, thereby reducing manufacturing costs.
Compared with the traditional charging method, the wireless charging system can indeed greatly improve the convenience of charging, so that it is stopped and charged, and the wireless charging device has lower space demand. In addition, relying on magnetic resonance wireless charging, it can theoretically be charged while walking, and even is expected to solve the range anxiety of pure electric vehicles.
For pure trams, the most reliable solution now is electromagnetic induction, which is more stable and reliable. Magnetic resonance is better than electromagnetic sensation thoughIt can have a higher power distance advantage (a few centimeters to a few meters), but it is difficult to control, high technical difficulty, and it is not easy to use for electric vehicles (which may be the development direction of wireless charging in the future).
As soon as the driver moves the car over the wireless charger, the system will automatically charge the car. A domestic electric vehicle company is also studying wireless charging technology, which has entered the experimental stage and may be mass-produced in the near future. In fact, wireless charging technology is not a tall technology, it is the use of electromagnetic induction principle or magnetic field resonance principle, to achieve the wireless transmission of electric energy.
At present, it is not hot, and only high-end mobile phones are equipped with wireless charging function, which can be imagined that the cost is not low. For now, the application of low-end machines is obviously not yet ripe. Wireless charging technology does not use charging lines at all, but uses magnetic fields to charge devices, and is inspired by wireless power transmission technology.
