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
Why It Matters

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.
