EV Charging + Storage Solutions
Pair energy storage with EV charging to add fast-charging capacity without costly grid upgrades, and to shield sites from demand charges.
The Challenge
Fast EV charging creates short, severe power spikes that can exceed a site’s grid connection and trigger high demand charges or expensive upgrades.
- Fast chargers demand more power than many grid connections allow
- Simultaneous charging events cause costly demand-charge spikes
- Grid capacity upgrades are slow and expensive
- Charging uptime affects customer and fleet satisfaction
How the System Works
The storage buffer charges slowly from the grid or on-site solar. When chargers demand a burst of power, the battery supplies the difference, so the site's grid draw stays within its connection limit. The EMS keeps peak demand — and the resulting charges — under control.
Buffer
Storage charges steadily from the grid or on-site solar at low power.
Boost
During charging peaks the battery supplements grid supply for fast delivery.
Protect
Peak draw stays within the connection limit, avoiding demand-charge spikes.
Typical System Architecture
The battery sits between the grid connection and the chargers. It charges slowly and discharges fast, so the grid only sees a steady, bounded draw even when multiple vehicles charge at once.
EV charging + storage topology: sources → PCS buffer → BMS → battery → chargers and site loads.
What Makes Up the System
Each StorXing solution pairs our LiFePO4 storage with the conversion, control and monitoring hardware needed for the application.

Buffer Battery Bank
Supplies extra power during simultaneous charging sessions.
Charger Interface
Coordinates buffer output with charger demand.
Energy Management
Keeps grid draw within the connection limit.
Site Monitoring
Tracks charger use, buffer state and demand charges.
