Which charging method uses on-board charger?
Car charger slow charging
On-board charging, also known as slow charging and on-board slow charging, uses a portable charging device carried in the vehicle to charge using a household charging socket.
Charging can directly use household two-phase AC power, household 220v power supply, supports 10A or air conditioner 16A output, and generally has a maximum power of about 3.5w. Therefore, the disadvantage of using a car charger for charging is very obvious, that is, the charging time is too long, but the cost of charging is not high. There is no need for a separate meter or a separate power line. It only requires a general household power supply. That’s it, the cost of use is very low, and it can also be used as a temporary emergency charging method when far away from fixed charging piles.
Home charging pile
For those who have a fixed parking space and can apply for a fixed charging pile, it is the most convenient to have a fixed charging pile of your own. You can charge as soon as you get home, or you can set an appointment for charging. Basically, when you go out the next morning It can ensure sufficient power and perfectly solve the problem of charging anxiety. In many cases, when purchasing an electric vehicle, the car dealer will give us a fixed charging pile and a certain length of free installation length. Some manufacturers also require us to purchase it separately. But it is inevitable that we still need to confirm the charging conditions, apply for a separate meter, and go through various procedures such as property management before we can use our own charging pile. In addition, there are also charges beyond the length of the free power cord. I heard that some riders have spent thousands on the power cord alone. Generally speaking, household charging piles are also AC slow charging piles with a rated voltage of 220V and a rated current of 32A, so the general power is about 7Kw and the speed is about 2 times that of on-board charging. On average, it takes 6-10 times to fully charge. Hour.
DC fast charging
Fast charging usually uses high-voltage direct current to directly charge the battery. The battery can be charged to about 80% of the power in a short time, so it is widely used in public charging piles. The voltage of this charging mode is generally between 150 and 400, and the power is high. The advantages of fast charging are high efficiency and short charging time. However, fast charging requires high voltage and power of the car, and may also cause the battery temperature to rise faster, causing adverse effects on the battery. Therefore, many manufacturers will pass DC fast charging. The heat dissipation technology cools the three-power system to ensure charging temperature and safety. Riders can search for charging stations through “Map” to find nearby charging stations to recharge their electric vehicles. They can also see the remaining number of charging piles and the power of the charging piles at any time.
The three charging methods can be said to have their own more suitable uses:
1. Fast charging can be used as a free charge when we are in a hurry to replenish power, or when we go out, such as shopping in a mall.
2. Home charging piles are used for our daily charging. After all, the car can be fully charged in just one sleep. It is basically the same as our daily use of mobile phones. It is very accustomed and convenient.
3. As for the car charger, it is a temporary charging method. When we go out and cannot find DC fast charging nearby, we can just find a household socket or air-conditioning socket to recharge the car. Although the speed is not fast, it is better than charging. No good.
