Many of our new energy vehicles are electric. Since they are electric, they need to be charged. The charging methods include charging with the car or charging piles. Generally, the batteries used in new energy vehicles are chemical energy batteries classified as power batteries. For the use environment of vehicles, in terms of design and production, products suitable for the characteristics of high current charging and discharging points have been selected as the carrier of power batteries. Let's have a look New energy vehicle charging pile What's the difference between car charging and charging post!
All the built-in chargers used for on-board charging use commercial power (220V). The power input power is limited, and they are all charged at home. Electric vehicles are not in urgent need. They can make full use of the low power period to charge and reduce the charging cost; The more important advantage is that it can deeply charge the battery, improve the charging and discharging efficiency of the battery, and extend the battery life.
The charging pile is a DC charging pile, which is fixed outside the electric vehicle, connected to the AC power grid with three-phase AC (380V), 50Hz frequency, adjustable DC output, and directly charges the power battery of the electric vehicle.
As the DC charging pile adopts three-phase four wire system for power supply, it can provide sufficient power, and the output voltage and current can be adjusted in a wide range, which can meet the requirements of fast charging. In terms of charging power, the charging pile can charge according to the high power of the vehicle mounted charger. This is because the charging pile is used to supplement the power of the electric vehicle, and the electric vehicle cannot be driven away for another half day. The charging power of ordinary socket equipment is generally about 2~3.5kW;
In terms of charging safety, the charging pile has the functions of electric leakage, lightning protection and waterproof, but ordinary sockets do not necessarily have these functions; In addition, the charging pile can communicate with the vehicle. If there is a fault, the charging current can be interrupted in time. The charger has high efficiency, which requires that the circuit design and manufacturing process of the charger itself must be high. Electric vehicle manufacturers focus on the design and process of electric vehicles, not the charger. That is to say, the efficiency is naturally low with less investment.
The above is about the difference between on-board charging and charging pile. I hope it can help you!
