Wind - Solar Energy Storage Charging Station

After using wind energy and solar energy to generateelectricity and store it in the

energy storage battery cabinet, and then provide clean energy power supplyfor the

charging pile through the EMS energy manage-ment system, and provide fast

charging service for newenergy vehicles.

1.Off-grid and grid-connected seamless switching

2.Play the function of "cutting the front and filling the valley" of the municipal

power grid

3.Improve power utilization and reduce costs

Wind-Solar Storage Charging Station

Cost comparison

Energy cost comparison

Energy consumption per 100 kilometers: Electric vehicles are 15-25% of gasoline powered vehicles.

Maintenance cost comparison

The most expensive batteries, motors, and electronic control components of electric vehiclesare generally guaranteed for life. Due to the large

number of mechanical components in fuel powered vehicles, they require frequent maintenance; Overall, compared to gasoline powered vehicles,

the average maintenance cost of electric vehicles has decreased by 22-40%.

About Charging Station

Charging station functions

Allow 10 vehicles to charge simultaneously (50KWH per vehicle).It can meet the charging needs of 100 vehicles per day.

Land For Charging Station Construction

Covering an area of 5000-6600 square meters, this system can meet the charging needs of vehicles within a range of 15-25 kilometers in the

surrounding area.

Investment Return On Charging Stations

Additional benefits: The charging station is equipped with cafes and supermarkets,which can shorten the investment cost recovery cycle.This

system can provide quick and safe charging service for 100 electric vehicles per day within the range of 15-25 kilometers. It can operate offline

or online. When operating offline, the site is not connected to the power grid. It is equipped with 5 sets of 120kW charging piles (dual gun) and

can simultaneously charge 10 vehi-cles (50KWH per vehicle).

Multipurpose Expansion & Application Of Charging Stations

According to demand, battery cabinets can be added to increase energy storage,suitable for areas with difficult power distribution. It can expand

industrial and commercial power station systems, rural island power station systems, and field operation engineering power station systems. The

capacity of wind and solar modules can be configured according to on-site terrain conditions.

Increase Investment Amount For Charging Station Expansion

Based on 100 electric vehicles per day, the charging capacity of each vehicle is calculated based on a 20 year service life, including equipment,

construction,shipping, installation, insurance, maintenance, accessories, and other expenses.The total investment amount is 1.68 million US dollars.

If the charging capacity of 200 vehicles per day is increased on this basis, the investment amount for the expansion of the charging station is

approximately 960000 US dollars. If thecharging capacity of 300 vehicles per day is increased on this basis, the investment amount for the expansion

of the charging station is 650000 US dollars.
