Project Background
Supporting the Rapid Growth of Industrial EV Adoption
With the rapid development of electric mobility in Southeast Asia, more industrial companies are deploying internal EV charging stations to support:
- Company electric vehicles
- Logistics fleets
- Electric forklifts
- Industrial transportation equipment
However, traditional grid-only charging solutions face increasing challenges, including high electricity costs, limited grid capacity, and unstable power supply.
To overcome these challenges, the customer introduced a PV + BESS + EV Charging integrated solution to optimize energy usage and improve charging reliability.
Customer Challenges
1. High Peak Demand Caused by EV Fast Charging
The charging station operates multiple DC fast chargers simultaneously, creating high instantaneous power demand.
During peak charging periods:
- Total charging power can reach approximately 360kW
- Existing transformer capacity was insufficient
- Grid capacity expansion required significant investment and additional fixed demand charges
The battery energy storage system works as a power buffer, reducing grid impact and avoiding expensive infrastructure upgrades.
2. Rising Industrial Electricity Costs
The factory experienced high electricity expenses due to:
- Daytime peak electricity tariffs
- Factory production loads overlapping with EV charging demand
- Limited solar energy utilization
The BESS enables:
- Charging during low-cost electricity periods
- Peak shaving during high-demand periods
- Increased solar self-consumption
3. Power Reliability Requirements
Industrial operations require stable power availability.
Frequent grid fluctuations and short-term outages could interrupt:
- EV fleet charging
- Forklift operation
- Internal logistics transportation
The energy storage system provides backup power support to improve energy resilience and maintain critical charging operations.
Energy Storage Solution
250kW/500kWh Containerized BESS Deployment,the project deployed a high-performance commercial energy storage system featuring:
