Solution · EV Charging

One charging-intelligence layer for home and depot.

Home charging and fleet or network charging share the same tariff context and signal foundation, but they execute against different readiness, concurrency, and demand constraints. WattShift gives EV software teams one economic layer to start from.

Customer outcomes

Give every charge decision a clearer economic reason.

Drivers and operators do not buy rate logic. They buy ready vehicles, lower cost, fewer demand surprises, and confidence that the product chose the right window.

Ready by the hour that matters

Use charging windows that respect departure time, driver expectations, and battery target without defaulting to blunt off-peak rules.

Price Signals

Lower site exposure

Keep fleet and network charging aware of site peaks, demand-charge risk, charger concurrency, and operational priority.

Utility Rate Database

Explain session economics

Translate tariffs, charge behavior, and monthly outcomes into cost proof that customers and operators can understand.

Impact Calculations

Shared layer, different execution

Same signal foundation. Different charging policy.

What is shared is the economic truth. What differs is the policy. Home charging needs ready-by logic and customer simplicity. Fleet and network charging need concurrency, demand management, and operational prioritization.

Home ready-by schedule

Optimize around departure time, target charge, and customer-visible simplicity.

Depot load window

Balance charger concurrency, site peaks, vehicle priority, and demand-charge exposure.

Fast Charging Demand Management

Compare immediate full-power charging against modulated charging that reduces monthly demand peaks.

Key Optimization Insights

  • EV charging shifts away from expensive peak windows.
  • Modulated power reduces demand-charge exposure.
  • Site load stays under a cleaner operating envelope.

Make the cheaper charging decision easier to trust.
