First, use the portable charger carried in the car. Electric vehicles will be equipped with portable chargers, so that the owners can charge through the household power supply. The main feature is convenience. But its charging speed is a little crazy, and it can only be used as another way to supplement electricity.
The second is the household charging pile. When buying an electric car, a household charging pile is usually given with the car, and technicians will be arranged to come to the door for installation and debugging. The charging time of this charging method is ok, which will vary with the brand and model of the vehicle, but the premise is that there is a parking space and the property allows you to install household charging piles in the parking space.
The third way is public charging piles. The advantage of this charging method is that you can choose DC fast charging and AC slow charging according to the actual situation, and it is also the only place that supports DC fast charging, but the disadvantages are also obvious. At present, there are few public charging piles, which are difficult to find and occupy, and the charging cost is high.
The fourth charging method is to change the battery. This is also the last resort of electric vehicles. Specially trained technicians can replace the battery within 2- 10 minutes through fully automatic or semi-automatic technology, thus achieving the refueling speed comparable to that of fuel vehicles. However, the shortcomings of this method are also obvious, and it can only be operated by professionals in professional locations.
Qualcomm Halo Wireless Charging System
You don't have to use a cable to charge the battery of an electric car. The mobile phone has realized the wireless charging function, and the battery of the electric car cannot be charged.
Wireless charging technology is actually based on the principle of electromagnetic induction, which transmits electric energy wirelessly in a certain space.
It is understood that many car companies and third-party technology companies have developed wireless charging technology. For example, the wireless charging system developed by Nissan for Leaf and the Halo wireless charging system developed by Qualcomm are relatively mature.
