At present, electric vehicles are quite popular, so batteries are very important in electric vehicles. At present, most electric vehicles can basically be charged at home. From the beginning, everyone didn't recognize it, and now almost every family has it. What was not recognized before was battery life. Then the current charging problem is well solved, and there is a reason to choose it. So how do you charge the electric car at home? Let's look at the car editor.

How to charge the electric car at home: wireless charging is also called inductive charging (convenient)

Induction charger is based on the transformer principle of high-frequency AC magnetic field, which induces electric energy from the primary side of the vehicle to the secondary side of the vehicle, thus charging the battery. The biggest advantage of induction charging is safety, because there is no direct point contact between the charger and the electric vehicle, so even in bad weather, such as rain and snow, there is no danger of electric shock when charging the electric vehicle.

How to charge the electric car at home: Use the traditional constant voltage and constant current charging method (commonly used) to charge the electric car.

The plug of the car charger can be charged as long as it is plugged into the power socket in the parking lot or at home, so most of the charging process is completed by the customer himself. Electricity is directly taken from the low-voltage lighting circuit, and the charging power is small, and it is supplied by the standard power supply of 220V/ 16A. Typical charging time is 8~ 10h(SOC is above 95%). This charging method has no special requirements for the power grid, as long as it can meet the power supply quality required for lighting. Because charging at home is usually at night or during low battery, which is conducive to the effective use of electric energy, most power departments will give electric vehicle users some concessions, such as charging concessions during low battery.

How to charge household electric vehicles: small charging station (ordinary)

Small chargers have been installed in streets, supermarkets, office buildings and parking lots. Charge with normal charging current. The electric driver can start charging as long as he stops at the designated position of the charging station and connects the wires. The charging method is coins or credit cards, and the charging power is mostly 5~ 10kW, using three-phase four-wire 380V power supply or single-phase 220V power supply. The typical charging time is: charging 1~2h, charging for 5 ~ 8h (SOC over 95%).

How to charge the electric car at home: fast charge?

The power of the charger is very large, most of which are basically above 30kW, using a three-phase four-wire 380V power supply. The typical charging time is 10~30 minutes. This charging method has a certain relationship with the battery life, especially the ordinary battery can not be charged quickly, because receiving a large range of electricity in a short time will affect the battery overheating. The key of the fast charging station is the fast charging module outside the car, which can output 35kW or even higher power. Because the ratings of power and current are basically high, this charging method requires a higher power grid, and most of them should be used near 10kV substation or in monitoring stations and service centers. Large charging stations (machines) often use this charging method.

How to charge the household electric vehicle: replace the battery (machinery)

In addition to the above charging method, you can also replace the battery pack, that is, when the battery is exhausted, replace the exhausted battery pack with a fully charged battery pack. Batteries belong to repair shops or battery manufacturers, and users of electric vehicles only need to rent batteries. Users of electric vehicles park their cars in a specific area, and then use a battery changer to take out the exhausted batteries and replace them with fully charged batteries. For the replaced uncharged battery, it can be charged in the repair shop or recycled centrally. Because the battery replacement process includes mechanical replacement and battery charging, it is sometimes called mechanical & Ldquo refueling & Ldquordquo.

How to charge the electric car at home: mobile charging (external conditions required)

Users of electric vehicles don't need to find a charging station, stop or spend time charging. The MAC system is buried under a section of road, that is, the toll area, and there is no extra space. Both contact and inductive MAC systems can be basically realized. For the contact media access control system, a contact arch should be installed on the underbody. By contacting with the charging element embedded in the road surface, the contact arch can obtain instantaneous large current. When the electric vehicle cruises through the MAC area, its charging process is pulse charging. For induction MAC system, the contact arch on the vehicle is replaced by induction coil, and the charging element embedded in the road surface is replaced by high current winding which can generate strong magnetic field.

Today, the introduction of automobile system ends here. The above is a brief introduction about how to charge household electric vehicles. At present, new energy vehicles are quite popular all over the country, so everyone pays more attention to the charging method. The most popular one should be charging at home, which is quite convenient. I hope the introduction of car system can solve your problem. I want to know more about the car series.
