2024-09-21
The electric vehicle charging system is an energy supply facility to maintain the operation of electric vehicles. The problem of electric vehicle charging is considered to be the "last mile" of electric vehicle promotion. Improving the electric vehicle charging system will help alleviate consumers' mileage anxiety about new energy vehicles and expand the consumer market for new energy vehicles.
Therefore, it is urgent to accelerate the construction of supporting infrastructure such as electric vehicle charging piles and battery swap stations. The "photovoltaic storage and charging" integrated charging station is an expansion and extension of the basic charging pile. Because it covers the three major links of photovoltaic power generation, energy storage system and charging, the "photovoltaic storage and charging" solution has received great attention from the industry. More and more BESS manufacturers are beginning to design and produce integrated photovoltaic storage and charging devices.In this article, we will introduce what the photovoltaic storage and charging integrated solution is, as well as its application areas and advantages.
What is a photovoltaic storage and charging machine?
A photovoltaic storage and charging machine is an integrated device that integrates photovoltaic power generation, energy storage and charging functions. Its working principle is based on the "photovoltaic + energy storage + charging" solution. The main purpose of this system is to achieve efficient use of renewable energy, reduce energy costs, and improve the reliability and stability of the energy system.
Application scenarios of integrated photovoltaic storage and charging equipment:
The application scenarios of "photovoltaic storage and charging" power stations can be roughly divided into four categories:
(1) Urban charging stations
Mainly referring to charging stations built in public parking lots, property communities, and shopping malls. By building "photovoltaic storage and charging" power stations in these places, the charging needs of urban private cars and operating and freight vehicles can be met. It is equivalent to a gas station in a city. The biggest feature is convenience. These vehicles have a long parking period, so high-power charging piles are not needed at this time;
(2) Highway service areas
Mainly to meet the needs of long-distance travel, at this time, high-power charging piles are needed to complete fast charging;
(3) Industrial parks
Where there is ample space for factory construction, safety is the primary consideration.
(4) In remote areas without power grids
Photovoltaic storage and charging can be used as an independent energy supply center to form a local microgrid to power electric vehicles or other electrical appliances.
The product performance parameters of the photovoltaic storage and charging machine usually include the following aspects:
Photovoltaic power generation:
refers to the power of the photovoltaic power generation part of the photovoltaic storage and charging machine, usually in kilowatts (kW). This parameter determines the maximum amount of solar energy that the system can convert.
Energy storage battery capacity:
refers to the battery capacity of the energy storage system in the photovoltaic storage and charging machine, usually in kilowatt-hours (kWh). This parameter determines the maximum amount of electrical energy that the system can store.
Charging power:
refers to the power of the charging facilities in the photovoltaic storage and charging machine, usually in kilowatts (kW). This parameter determines the speed at which the system charges electric vehicles and other equipment.
System efficiency:
refers to the overall energy conversion efficiency of the photovoltaic storage and charging machine, usually expressed as a percentage. This parameter reflects the system's conversion efficiency from solar energy to electrical energy.
The advantages of the integrated photovoltaic storage and charging machine are mainly reflected in the following aspects.
Environmental protection:
Using renewable energy, environmental protection, no carbon emissions, and help achieve carbon neutrality.
Reduce the impact on the power grid:
At present, the power of a single DC fast charging pile is more than 60kW. The operation of a DC fast charging pile is approximately equivalent to the electricity consumption of thirty households, which has a great impact on the power grid. After using the integrated photovoltaic storage and charging station, electricity can be obtained from the energy storage battery. The use of energy storage batteries helps the power grid to reduce peak loads and fill valleys, which can reduce the impact on the power grid accordingly. For example: HT 100KW/233KWH photovoltaic storage and charging integrated outdoor cabinet, the machine comes with 2 11KW AC charging guns or direct 100KW DC output, which can quickly charge electric vehicles.
Monitoring and remote management:
HT cloud platform photovoltaic storage and charging integrated system has monitoring and remote management functions. Users can monitor the performance of the system in real time through smartphone applications or web interfaces, including solar power generation, energy storage status, and electric vehicle charging status. This helps users better understand and optimize the operation of the system.
Energy management and automation:
HT INFINITE POWER integrated photovoltaic storage and charging system adopts intelligent energy management and automation technology. The system automatically adjusts the operation of photovoltaic power generation, energy storage and charging to maximize the use of renewable energy while ensuring a stable supply of electricity.
Easy installation and flexible configuration:
Due to the integrated solution, photovoltaics, energy storage batteries, charging piles, EMS energy management platform, cloud platform remote monitoring, etc. are integrated. There is no need for secondary testing and matching of each independent system, and multiple machines can be connected in parallel for capacity expansion. Compared with traditional charging pile solutions, the integrated photovoltaic storage and charging machine occupies a small area, is easy to install, and achieves true plug-and-play.
Economics:
Government incentives and subsidies. Different regions offer various government incentives and subsidies to encourage the installation of solar energy and energy storage. Users should understand local policies and regulations to determine whether they are eligible for incentives and subsidies.
Complementarity:
The output of photovoltaic power generation is affected by weather and light intensity, and is unstable and intermittent. The energy storage system can store excess electricity and release electricity when the photovoltaic output power is insufficient, thus ensuring the stable operation of the system. This complementarity enables the photovoltaic storage and charging integrated machine to better adapt to different environments and weather conditions.
Synergy:
Photovoltaic and energy storage systems work together in the photovoltaic storage and charging machine to achieve efficient energy utilization. The electricity generated by photovoltaic power generation can be directly supplied to the charging facilities or stored in the energy storage system for release when needed. This synergy enables the photovoltaic storage and charging machine to respond to changes in energy demand more flexibly.
Balance:
The energy storage system in the photovoltaic storage and charging integrated device can also balance the load of the power grid. During peak load periods, the energy storage system releases electricity to reduce the pressure on the power grid; during low load periods, the energy storage system stores electricity to prepare for subsequent charging services. This balance enables the photovoltaic storage and charging integrated device to better integrate with the power grid and improve the stability and reliability of the entire energy system.
In summary, photovoltaics and energy storage are interconnected and complementary in the photovoltaic storage and charging integrated machine, forming an efficient, stable and sustainable energy system. This system not only improves the utilization efficiency of renewable energy and reduces energy costs, but also provides convenient and reliable charging services for electric vehicles and other equipment, promoting the process of energy transformation and sustainable development.
