Integrated energy solutions combine EV charging infrastructure with renewable energy and power management technologies such as solar PV, battery energy storage systems (BESS), energy management systems (EMS), grid power, transformers and switchgear.

By integrating these systems into one coordinated energy platform, commercial and industrial projects can optimize power distribution, manage peak demand, increase renewable energy utilization and support high-power EV charging.

A complete integrated EV charging solution can include solar PV panels, DC fast EV chargers, AC EV chargers, BESS, EMS, transformers, switchgear, power distribution equipment and grid connections.

Depending on the project requirements, the system can be configured as:

• Grid + EV Charging
• Solar PV + EV Charging
• BESS + EV Charging
• Solar PV + BESS + EV Charging
• Solar PV + BESS + Grid + EV Charging
• Off-grid solar + BESS + EV Charging

The final configuration is designed according to the site’s power capacity, charging demand, renewable energy potential and operating requirements.

Solar PV generates electricity during daylight hours and can directly supply energy to EV charging stations. Excess solar generation can be stored in a BESS or exported to the grid, depending on the project configuration.

For commercial charging sites, integrating solar PV with EV chargers can increase renewable energy utilization and reduce dependence on grid electricity during suitable operating periods.

Solar PV capacity can be scaled according to the available installation area and expected charging load, from commercial systems of tens or hundreds of kWp to 1 MW+ large-scale solar PV systems.

A Battery Energy Storage System (BESS) can help manage the high and fluctuating power demand created by DC fast charging.

A BESS can be used for:

• Peak shaving and demand charge management
• Reducing instantaneous grid power requirements
• Supporting high-power EV charging
• Storing excess solar energy
• 提高再生能源的自用比例
• Providing backup or supplemental power where required

For charging hubs with limited grid capacity, BESS can be an important part of the overall power management strategy.

In many projects, yes. An integrated system can use BESS, EMS and intelligent load management to control the amount of power drawn from the grid.

For example, when multiple high-power DC chargers operate simultaneously, the EMS can dynamically distribute available power between EV chargers, BESS, solar PV and the grid.

This can help reduce peak grid demand and potentially minimize the need for costly transformer or grid-capacity upgrades. The actual benefit depends on the site’s existing grid capacity, charging profile and local utility requirements.

Our integrated energy solutions can be designed for applications ranging from commercial AC charging to high-power DC fast charging and ultra-fast charging.

Typical project configurations may include:

• 7–44 kW AC EV charging
• 60–120 kW DC fast charging
• 120–240 kW high-power DC charging
• 320–480 kW commercial and fleet charging
• 480–960 kW+ high-power charging hubs
• 1 MW+ scalable ultra-fast charging infrastructure

The actual charger configuration, number of charging points and total system capacity are customized according to the project load profile and vehicle requirements.

Integrated energy solutions are suitable for a wide range of commercial, industrial and transportation applications, including:

• Commercial EV charging stations
• Fleet and logistics charging depots
• Electric bus charging facilities
• Highway and public charging hubs
• Shopping malls and retail parking
• Office and workplace charging
• 飯店與度假村
• 工業園區
• Mining and heavy-duty vehicle sites
• Transportation and logistics centers

The system can be configured differently depending on charging demand, available land, grid capacity and renewable energy resources.

是的。我們提供 project-oriented EV charging and integrated energy system solutions rather than simply supplying individual charging equipment.

Based on the project information, we can help configure:

• EV charger quantity and power
• Solar PV capacity
• BESS capacity
• Transformer and switchgear requirements
• EMS and energy management strategy
• Grid connection architecture
• Power distribution system
• Charging load management
• Communication and OCPP requirements

For EPC companies, charging operators, distributors and commercial project developers, the solution can be further customized according to local standards and project specifications.

Yes. A grid-connected integrated system can coordinate solar PV, BESS, EV chargers and grid power through an Energy Management System (EMS).

The EMS can monitor power generation, battery state of charge, EV charging demand and grid power consumption, then dynamically control power distribution.

A typical energy flow can be:

Solar PV → EV Charging / BESS

Grid → EV Charging / BESS

BESS → EV Charging

The exact operating strategy can be configured for objectives such as peak shaving, solar self-consumption, charging load management or backup power.

To design a suitable solution, we normally recommend providing the following project information:

• Project location and country
• Number and type of EVs
• Required number of charging points
• Required AC/DC charging power
• EV connector standard, such as CCS1, CCS2 or GB/T
• Existing grid voltage and available power capacity
• Solar PV installation area or target PV capacity
• Required BESS capacity or available installation space
• Daily charging energy or expected charging schedule
• Peak charging demand
• OCPP/CMS and EMS requirements
• Local electrical and certification requirements

Based on these parameters, we can develop the appropriate EV charging, solar PV, BESS, EMS, grid and electrical infrastructure configuration for the project.
