Cars & Vehicles
Specialized calculators for vehicle payload, EV‑to‑home energy, EV‑to‑grid scenarios, and the German THG quota. All tools run locally in your browser to keep your data private.
Plan real‑world use cases like loading a van, using your EV as a backup power source, feeding energy back into the grid, or estimating your annual THG‑quota payout in Germany.
Energy and tax‑related outputs are approximations for personal orientation only and must not be treated as binding financial, legal, or tax advice.
Payload & Loading
Check how much weight you can legally load into your car, van, or small truck within EU regulations. Avoid overloading fines and improve safety on long trips.
Vehicle-to-Home & Vehicle-to-Grid
Estimate how your electric vehicle can support your home as a temporary battery or feed energy back into the grid, using typical efficiency and consumption assumptions.
Vehicle-to-Home Calculator
Estimate how long your EV can power your household at different power levels, considering usable battery capacity and inverter efficiency.
Open ToolVehicle-to-Grid Calculator
Simulate feeding energy from your EV back into the grid, including cycle depth, potential revenue, and impact on usable driving range.
Open ToolTHG Quota (Germany)
Estimate your annual German THG quota payout based on typical certificate values and your EV ownership. All results are rough estimates for personal orientation only.
Frequently Asked Questions
Common questions about the Cars & Vehicles tools on LocalCalcs.
Are these vehicle calculators legally binding?
No. All calculators provide approximate results for personal orientation only. They do not replace official type approval data, professional legal, tax, or engineering advice.
Which countries are these tools designed for?
The payload and THG quota tools are optimized for EU and especially German users. Vehicle-to-home and vehicle-to-grid tools use generic assumptions and can be used internationally.
Do you store any vehicle or personal data?
No. All calculations run locally in your browser. Inputs like weights, battery sizes, tariffs, and license plate–related details are processed only on your device and are not sent to a server.
Where do the THG quota values come from?
The THG calculator uses typical market ranges and published reference values as a basis for orientation. Actual payouts depend on your chosen provider and current market prices.
Can I use the results for contracts or official applications?
No. Always double‑check with official documents, your energy provider, THG broker, or relevant authority before making binding decisions or signing contracts.
