Charging Stations For Electric Cars

Electric car and charging station
An electric vehicle is a vehicle that is driven by a vehicle power source and driven by a motor to meet the requirements of road traffic and safety regulations. As the impact on the environment is smaller than that of traditional cars, its prospects are widely optimistic.
Types of electric vehicles: pure electric vehicles, hybrid vehicles, fuel cell vehicles.

Electric car and charging station Pure electric
A pure electric vehicle is driven by an electric motor.
Pure electric vehicles, relative to fuel vehicles, the main difference (different) lies in four major components, drive motors, speed controllers, power batteries, and car chargers. Relative to the gas station, it consists of a public ultra-fast charging station. The difference in quality of pure electric vehicles depends on the four components, and the value depends on the quality of the four components. The use of pure electric vehicles is also directly related to the selection and configuration of the four major components.
The speed of a pure electric vehicle is fast and slow, and the starting speed depends on the power and performance of the driving motor. The length of its continuous mileage depends on the size of the vehicle's power battery. The weight of the vehicle's power battery depends on which power battery is used, such as lead acid and zinc. Carbon, lithium batteries, etc., their volume, specific gravity, specific power, specific energy, cycle life are all different. This depends on the manufacturer's positioning and use of the vehicle grade as well as market definition and market segmentation.
The driving motor of pure electric vehicle has DC brush, brushless, permanent magnet, electromagnetic, and AC stepping motor. Their selection is also related to vehicle configuration, use and grade. In addition, the speed control of the drive motor is also divided into step-level speed regulation and stepless speed regulation. There are electronic speed controllers and speed controllers. The motor has a hub motor, an inner rotor motor, a single motor drive, a multi-motor drive, and a combined motor drive.
Advantages: The technology is relatively simple and mature, and can be charged as long as there is power supply.
Disadvantages: The storage capacity of the battery unit weight is too small, and because the battery of the electric vehicle is relatively expensive, and the economic scale is not formed, the purchase price is relatively expensive. As for the use cost, some of the use price is more expensive than the car, and some prices are only for the car 1 /3, this depends mainly on the battery life and local oil and electricity prices. Electric vehicle technology is still immature, charging technology, cruising range, reliability and other aspects still need to be improved, and the disposal of scrapped batteries and optimization of power grid systems are also key issues to be solved.

Hybrid Charging station series hybrid car
Refers to a car that can at least derive power from the energy stored in two types of vehicles:
A consumable fuel or rechargeable energy/energy storage device.
According to the structure of the power system, it can be divided into the following three categories:
Tandem hybrid car: The driving force of the vehicle is only derived from the hybrid (electric) car of the electric motor. The structural feature is that the engine drives the generator to generate electricity, and the electric energy is sent to the motor through the motor controller, and the motor drives the car to travel. In addition, the power battery can also provide power to the motor alone to drive the car.
Parallel hybrid vehicle: A hybrid (electric) vehicle in which the driving force of the vehicle is supplied simultaneously or separately by the electric motor and the engine. The structural feature is that the parallel drive system can use the engine or the electric motor alone as the power source, or can use the electric motor and the engine as the power source to drive the car at the same time.
Hybrid hybrid car: Hybrid (electric) car with series and parallel drive. The structural feature is that it can work in series mixing mode or in parallel mixing mode, taking into account the characteristics of series and parallel.
(Note: With the development of hybrid electric vehicle technology, its type is not limited to the above, and can be divided according to other types.)
Those that typically use conventional fuels, coupled with an electric motor/engine, improve low-speed power output and fuel consumption. In the domestic market, the mainstream of hybrid vehicles is gasoline hybrid, and the development of diesel hybrid vehicles in the international market is also very fast.
advantage:
1. After the hybrid power is used, the maximum power of the internal combustion engine can be determined according to the average required power, and the working condition is under the optimal working conditions of low fuel consumption and low pollution. When the power of the high-powered internal combustion engine is insufficient, it is supplemented by the battery; when the load is low, the surplus power can generate electricity to charge the battery. Since the internal combustion engine can work continuously, the battery can be continuously charged, so the stroke is the same as that of the ordinary automobile.
2. Thanks to the battery, it is very convenient to recover the energy during braking, downhill, and idling.
3. In the prosperous urban area, the internal combustion engine can be shut down and driven by batteries to achieve “zero” emissions.
4. With the internal combustion engine, it is very convenient to solve the problems encountered in pure electric vehicles such as air conditioners, heating, and defrosting.
5. You can use your existing gas station to refuel without having to invest again.
6. The battery can be kept in good working condition without overcharging and over-discharging, prolonging its service life and reducing costs.
Disadvantages: Long-distance high-speed driving is basically not fuel-efficient.
The fuel cell
A car that uses a fuel cell as a power source. The chemical reaction process of a fuel cell does not produce harmful products, so electric car
electric car
Fuel cell vehicles are pollution-free vehicles. The energy conversion efficiency of fuel cells is 2 to 3 times higher than that of internal combustion engines. Therefore, fuel cell vehicles are an ideal vehicle for energy utilization and environmental protection.
A single fuel cell must be combined into a fuel cell stack to obtain the necessary power to meet the requirements of the vehicle.
In recent years, significant progress has been made in fuel cell technology. World-renowned automakers such as DaimlerChrysler, Ford, Toyota and General Motors have announced plans to bring fuel cell vehicles to market by 2004. At the moment, prototypes of fuel cell cars are being tested, and fuel cell-powered transport buses are undergoing demonstration projects in several cities in North America. There are still technical challenges in the development of fuel cell vehicles, such as the integration of fuel cell stacks, the improvement of commercial electric vehicle fuel processors and the auxiliary automobile manufacturers are working towards integrating components and reducing component costs. Significant progress has been made.
Compared with traditional cars, fuel cell vehicles have the following advantages:
1. Zero emissions or near zero emissions.
2. Reduces water pollution caused by oil leakage.
3. Reduce greenhouse gas emissions.
4. Improve fuel economy.
5. Improve engine combustion efficiency.
6. Smooth operation and no noise.

The charging pile is similar in function to the tanker inside the gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can be based on different voltage levels. Charge various types of electric vehicles. The input end of the charging post is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. The charging pile generally provides two charging modes of normal charging and fast charging. One can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile, and perform corresponding charging mode, charging time, cost data printing and the like. The charging pile display can display data such as charge amount, cost, and charging time.
