The market for electric cars and charging piles is becoming increasingly sophisticated and large, and most people have embraced the use of electric cars. The electric car market has emerged in the spring. What about the charging pile market? Of course there are flowers.
But how much do you know about charging piles? I will give you a few lessons today.
1. What is a charging pile?
Is electric vehicle charging pile in the most important facilities in electric system, generally fixed on the side of the road or in the parking lot, using special charging interface, adopts the conduction method to provide electricity for electric cars on-board battery pack, in practical use, general ac charging pile and dc charging machine has two forms, for commercial purposes of charging pile will also include the corresponding network communications, credit card billing, used to make an appointment, etc.
One-piece dc charging pile
(380V, 90KW)
Product features:
Safe and reliable
15 inch LCD screen
Variety of charging modules
2. Common classification of electric car charging piles
(1) classification by installation conditions
Vertical charging pile and wall-mounted charging pile
(2) classification of service objects
Public charging piles, special charging piles and self-charging piles
(3) classification by installation site
Indoor charging pile, outdoor charging pile
(4) classify the number of charging ports
A charging pile and a charging pile
(5) classification by charging type
Ac charging pile and dc charging pile
3. The difference between ac charging pile and dc charging pile
Working principle of ac charging pile: pile - OBC - car
Working principle of dc charging pile: pile - car
Average charging time of ac charging pile: 6~10 hours
Average charging time of dc charging pile: 0.3~1.0 hours
4. Electric car charging mode
Charging mode 1
Electric QiCheLian received ac power (power), used in power supply side to meet the requirements of GB and 2099.1 GB 1002 plug and socket used in power supply side phase line and neutral line and earthing protection of the conductor. (currently the national standard has disabled charging mode 1)
Charging mode 2
Electric QiCheLian received ac power (power), used in power supply side to meet the requirements of GB and 2099.1 GB 1002 plug and socket used in power supply side phase line and neutral line and grounding protection of conductors, and installed in the charging connection cable on line control protection device.
Charging mode 3
Electric QiCheLian received ac power (power), using a special power supply equipment, will be directly connected to ac power grid electric cars, and in the special power supply equipment installed on the control guide.
Charging mode 4
When connecting an electric car to an ac or dc power grid, a dc power supply device with control guide function is used.
Free and open jiangmen maximum charging station
5. Connection mode of electric vehicles
Connection mode A
When connecting electric vehicles and ac power grids, use the charging cables and power plugs that are permanently connected to electric vehicles.
Connection mode B
Use an independent active cable assembly with a vehicle plug and a power supply plug when connecting the electric car and the ac power grid.
Connection mode C
When connecting the electric car and the ac power grid, use the charging cable and the vehicle plug that is permanently connected to the power supply device.
What is an electric machine?
The motor is a component that converts battery power to mechanical energy and drives the wheel of an electric car.
100KW electric car drives the motor
Product features:
Speed range width
Transient characteristics are better
Energy saving, efficiency and heat dissipation
Structural diversification
7. What is the significance of choosing the power of the motor?
The selection of motor rated power is a very important and complex problem. Load, if the motor rated power is too big, the light load operation of the motor is frequently, the capacity of the machine itself can not get sufficient play, into a "big mara car", at the same time, the motor efficiency is low, the performance is not good, will increase operating cost. The motor rated power, in turn, requires little, that is "small mara carts", motor current more than rated current, the motor loss increase, efficiency low, it is important to affect the service life of the motor, even if the overload is not much, the life of the motor can also be reduced more; Overload more, can damage the insulation of motor insulation material and even burn. Of course, the motor has a low rated power, which may not be able to drag the load at all, which will cause the captain to be in a start-up state while overheating and damaging. Therefore, the rated power of the motor should be selected strictly according to the operation of electric vehicles.
