The Energy Brain
for
Charging Infrastructure
ergOptimize decides when to charge, from what source, and at what power level. It forecasts both fleet demand and energy supply, then optimizes every charging session for lowest cost and dispatch readiness. When you're ready, it designs the solar, BESS, and grid infrastructure to match.
Predictive Optimization, Not Reactive Switching
Reactive / Responsive
- Responds to current conditions: grid load, available solar, battery state
- Switches energy sources as thresholds are hit
- Simple rule-based scheduling, no multi-variable optimization
- No forward-looking demand or supply modeling
- Misses cost-saving windows it can't anticipate
Forecasted & Predictive
- Forecasts both demand (fleet schedules, duty cycles) and supply (grid pricing, solar yield, BESS state)
- Plans charging schedules hours and days ahead
- Multi-variable constrained optimization: SoC targets, dispatch deadlines, capacity limits, tariff windows
- Equipment-specific modeling for accurate generation and load prediction
- Continuously learns from operational data to sharpen forecasts
Most charging systems react to conditions as they happen.
ergOptimize models what's coming and plans around it.
Reactive systems respond to current grid load or available solar. ergOptimize builds a predictive model across both sides of the equation: forecasting demand from fleet schedules and duty cycles, forecasting supply from grid pricing windows, solar generation curves, and BESS dispatch, then optimizing every charging session against that complete picture.
How It Works
Connect
Integrate with your existing systems. No hardware changes needed.
Model
ergOptimize ingests fleet schedules and duty cycles to model demand. Its predictive engine independently forecasts supply: grid pricing, solar generation, BESS availability.
Optimize
Constrained optimization across demand and supply. Load balancing, demand charge management, tariff arbitrage. Every vehicle charged at lowest cost.
Scale
Ready to go beyond grid-only? Design solar + BESS infrastructure based on actual operational data.
Operational Charging Intelligence
Real-time energy intelligence that decides when to charge, from what source, and at what power level. The optimization engine models fleet demand independently from energy supply, then solves across both to find the lowest-cost, dispatch-safe charging schedule.
Demand Forecasting
Models fleet charging demand from dispatch schedules, duty cycles, route requirements, and historical consumption patterns. Knows what your fleet needs before operations begin.
Supply Forecasting
Independently forecasts energy supply: grid pricing windows, solar generation curves, BESS state-of-charge, and demand charge thresholds. Plans charging around what's coming, not what's happening now.
Tariff & Demand Charge Optimization
ToD tariff arbitrage, peak demand management, and load smoothing. Keeps your demand profile flat and your energy costs structurally lower.
Continuous Learning
The optimization engine refines its models from operational performance. Every cycle sharpens the demand and supply forecasts. Every session improves cost efficiency.
Design the Right Energy Infrastructure
When you're ready to go beyond grid-only, ergOptimize models your actual operational patterns (duty cycles, routes, uptime requirements) to right-size the solar, BESS, and grid configuration that maximizes fleet uptime and project returns.
Infrastructure Design Intelligence
Most solar+storage designs start from generic load assumptions. ergOptimize starts from your actual fleet demand: the charging loads your vehicles create, the dispatch schedules that constrain them, and the energy economics that define the business case.
- Equipment-specific simulation (solar PV, inverters, batteries)
- Right-sized solar + BESS + grid design based on real fleet demand
- Multi-dimensional optimization across hundreds of design parameters: equipment configurations, sizing ratios, dispatch constraints, and economic variables
- Bankable P50/P90 energy yield projections
- EaaS pricing and PPA recommendations
Works With Your Existing Infrastructure
ergOptimize is the intelligence layer between your fleet and the grid. It works alongside your existing systems, whether that's charge point management, vehicle telematics, energy meters, or load management controllers, delivering optimized charging schedules however your infrastructure needs to receive them.
- Integrates with your existing charging and energy management systems
- Compatible with third-party dynamic load management controllers
- Adapts to your operational setup, no single integration path assumed
- No changes to existing hardware
- Integration tailored to your infrastructure
