The Energy Brain for EV Fleet Charging
Optimize Every Charge. Protect Every Asset.
Protect your electrical infrastructure with intelligent load balancing. Cut energy costs with real-time charge optimization. For solar + storage depots, design optimal energy infrastructure from day one. ergOptimize is the intelligence layer between your fleet and the grid.
Load Balancing
Protect infrastructure from demand spikes.
Cost Optimization
Minimize demand charges & energy costs.
Solar + Storage Design
Right-size your energy infrastructure.
One Platform. Two Powerful Capabilities.
Design It Right. Run It Smart.
Operational Charging Intelligence
Minimize energy costs on every charge, every day.
Acts as real-time energy intelligence that decides when to charge from solar, when to use battery storage, and when to draw from the grid based on forecasted solar generation, time-of-day tariffs, and fleet schedules
- Grid-only depot optimization: ToD tariffs, demand charge management, and fleet scheduling.
- Forecasted solar-aware charging schedules
- Dynamic grid pricing optimization (ToD arbitrage)
- Peak demand management & load smoothing
- Continuous learning from operational performance
Infrastructure Design Intelligence
Already optimizing grid-only? Add solar + storage when you're ready.
Design the right energy system from day one.
Models your fleet's actual operational patterns including duty cycles, routes, and uptime requirements. It optimizes the solar, BESS, and grid configuration that maximizes fleet uptime and project returns.
- Right-sized solar + BESS + grid design
- Bankable P50/P90 energy yield projections
- EaaS pricing & PPA recommendations
- IRR optimization across design variables
How It Works
Connect Your Fleet
Plug into your existing CPMS and chargers via API. No hardware changes needed.
Model Your Operations
ergOptimize ingests your fleet schedules, duty cycles, routes, and uptime requirements to understand your energy demand.
Optimize Every Charge
Real-time load balancing, demand charge management, and ToD tariff arbitrage. Every vehicle charged at lowest cost.
Add Solar + Storage
Ready to go beyond grid-only? ergOptimize designs the optimal solar + BESS + grid configuration based on actual data.
Forecasted Intelligence, Not Reactive Switching
Most systems just use solar when it's available and switch to grid when it's not. ergOptimize predicts and plans ahead.
Reactive / Responsive Approach
- Uses solar power only as it becomes available
- Switches to grid when solar is insufficient
- Simple rules, no multi-variable optimization
- No equipment-specific modeling
- Wastes solar capacity during off-peak charging
ergOptimize's Forecasted Approach
- Predicts solar generation and plans charging around it
- Optimizes grid usage around pricing periods proactively
- Multi-variable optimization: SoC, target time, grid load, pricing
- Equipment-specific solar simulation (modules, inverters, DC/AC)
- Maximizes renewable energy utilization at every interval
Current solar forecasting tools use basic weather data and generic calculations. Current charging optimizers use simple time-based scheduling. ergOptimize bridges both: advanced solar simulation meets intelligent charging optimization powered by a Constrained optimization engine that balances solar, grid, pricing, and fleet variables simultaneously.
Your Role. Your Value.
Charging & Energy Companies
You build and operate charging infrastructure. ergOptimize gives you an energy intelligence layer that reduces charging costs from day one, starting with grid optimization across tariffs and demand charges, and scaling to solar + storage design when you're ready.

Use Cases
Depot Charging for EV Fleets
Optimize depot charging for logistics and transportation. Start with grid-only optimization across time-of-day tariffs and demand charges to reduce costs immediately. Add solar generation and battery storage to unlock further savings when ready.
Mixed-Use Facilities
Design charging infrastructure that serves both fleet vehicles and building load. Our optimization accounts for competing demand and identifies the solar + BESS configuration that serves both efficiently.
Opportunity Charging Hubs
Plan mid-route charging stations with solar and storage. Model vehicle arrival patterns, dwell times, and energy requirements to right-size infrastructure for maximum utilization.
