The demand for electric vehicles is gradually rising globally, which is unsurprising considering the growing environmental awareness. As more drivers switch to EVs, the need for flexible and reliable charging solutions is also increasing. 

A split-type EV charging station is one such solution. Split chargers usually refer to a device that physically separates the charger’s charging part from the power conversion part. It can achieve maximum charging flexibility when combined with a solar energy storage system. 

A split charger addresses some key challenges faced in conventional EV charging installations. Its modular design allows for flexible placement of system components, improving space utilization. 

When combined with solar energy storage, split chargers provide cleaner, more sustainable fueling for EVs.

Split Car Chargers: Differences and Advantages Compared to Integrated Chargers

The split car charger upends traditional EV charging station design by separating components rather than housing all elements together in integrated machines. 

This new design of station architecture unlocks benefits unattainable by conventional single-unit chargers. The following aspects highlight the differences and advantages that make split chargers superior:

Flexible Installation

The separation design of the split charger gives installers freedom to carefully evaluate each location’s logistical parameters like accessibility, grid connections, physical barriers, and utilizing a diverse range of spaces. 

It allows for customized installation plans based on actual needs and sites, while integrated chargers are usually designed as one unit with relatively fixed installation positions and methods, making them less flexible than split-type chargers.

Convenient to Use

Due to the modular design, the split-type charger allows power and expansion charging units to be configured as needed. This flexibility is particularly important in large stations or situations that require high flexibility and scalability, such as high-traffic highways and commercial centers. 

Integrated chargers are usually designed to be simple, easy to operate, and suitable for public charging stations and other places. However, it limits the number of vehicles that can be charged simultaneously.

Convenient Maintenance

The maintenance and repair of split chargers are relatively more convenient. Each component operates independently and can be repaired or replaced separately without affecting the entire system if any part fails. 

In addition, technicians can inspect, clean components, or update software on the charging unit according to requirements.

Due to the integration of the main control and modules, integrated chargers may require overall maintenance for a malfunction, which may result in longer downtime and affect user convenience and experience.

Space Saving

Split car chargers allow for the allocation of rectifier cabinets and charging terminals based on terrain and available space, making more efficient use of existing space, especially suitable for spaces with limited space. 

Integrated chargers are usually designed as one unit. It will affect the installation of the charger if the available space is small.

Intelligent Power Distribution

The split-type charger can adjust and allocate power in real-time through an intelligent system based on the power grid, the charging needs of vehicles, and the user’s usage habits. According to the distribution information, the rectifier cabinet can ensure on-demand output power.

In addition, some split charging systems can dynamically adjust the power allocated to each charging station based on each vehicle’s actual needs.

The potential of Combining Split Car Chargers with Solar Energy Storage Systems

Integrating a split charger with solar energy storage amplifies its inherent flexibility. Solar panels convert daylight into electricity stored in batteries for use around the clock or when grid power isn’t available. 

This hybrid system strengthens the charging infrastructure. Key potentials include:

Optimize Energy Management

A centralized energy management system acts as the “brain” to intelligently schedule energy usage and distribution between the various integrated components for maximum efficiency. 

The split charger that combines solar energy storage systems can utilize solar energy as the main power source and store excess solar power through an energy storage system. The stored solar electricity can be used to charge electric vehicles at night or on cloudy days. 

This optimizes the power flow between the grid, batteries, and chargers to reduce waste and lower operating costs.

Flexibility and Scalability

The design of the split charger allows for flexible configuration and expansion of charging points as needed. 

Solar panels and storage systems can also easily expand the size of charging and energy storage systems according to user needs, adapting to charging needs of different scales. 

Moreover, separately installing components minimizes disruption to existing infrastructure and services. This flexibility greatly expands the application of EV charging stations.

Improve System Reliability

Combining split chargers and solar energy storage systems can provide higher system reliability. Even if one charging terminal malfunctions, other modules can still operate normally. 

In addition, solar energy storage systems can serve as backup power during grid failures or high electricity prices. Their built-in protection components further enhance the reliability of the entire system.

Thus, robust components combined with preventive maintenance can prevent malfunctions.

Improve Charging Speed

A high-powered split charger benefits greatly from intelligent energy distribution. For example, when there are fewer electric vehicles, the split charger can increase the output power according to the owner’s needs, thereby shortening the charging time. 

Pairing with solar and energy storage systems also allows for adjusting charging power based on grid load and vehicle demand, providing faster charging services without increasing grid burden. 

Faster fueling reduces drivers’ waiting time for daily commutes.

Support Sustainable Development

Independently producing electricity with renewable energy resources lowers operating costs. Using solar energy to charge electric vehicles reduces reliance on fuels and lowers greenhouse gas emissions.

Over time, wide adoption of the integrated solution for solar, energy storage, and charging would help transition the transportation sector onto a decarbonized path.

Intelligent Management

Through intelligent management systems such as apps, users can monitor solar power generation, energy storage system status, and electric vehicle charging in real time. 

Users can also remotely control the charging process through the app and adjust the charging plan to use electricity reasonably.

Intelligent control systems have improved the flexibility of photovoltaic storage and DC charging solutions, which is in line with the future trend of electric transportation and renewable energy development.
