Smart energy management system optimizes home energy use

Photovoltaic methods, battery storage items, and electrical automobiles—non-public households are more and more turning in the direction of economical and climate-friendly applied sciences. Nonetheless, the complete potential of those applied sciences can solely be unleashed in mixed use.

RAZO Power, a start-up based at Karlsruhe Institute of Know-how (KIT), gives an clever vitality administration system that hyperlinks vitality sources and constructing know-how, optimizes self-consumption, and will increase general effectivity. RAZO Power will likely be current on the KIT sales space within the “Energy Solutions” space of Hannover fair from March 31 to April 4, 2025 (Corridor 13, Sales space C76).

The growing electrification of the vitality sector just isn’t solely altering the best way we generate vitality, but in addition how we use it. Many householders, nonetheless, are usually not in a position to leverage the complete potential of their photovoltaic systems and battery storage items—typically attributable to insufficient management performance.

“Many systems can’t be networked as intelligently as their manufacturers promise. Moreover, the existing solutions are often too complicated or don’t allow users to control their energy consumption efficiently,” says Max Schütze, one of many founders of RAZO Power.

To vary this, the start-up developed a cloud-based platform that coordinates numerous vitality sources and electrical shoppers in an automatic approach. “Our system enables a dynamic adjustment of the energy flow and ensures the efficient use of renewables,” says Schütze. Because of this electrical automobiles, for instance, are charged primarily at occasions when ample solar energy is on the market or grid energy is least expensive.

Synthetic intelligence allows advanced forecasts

Due to RAZO Power’s clever charging administration, noticeable price financial savings are potential. For instance, e-vehicle customers have been in a position to cut back their price per hundred kilometers from round six euros to a median of solely two euros—decided by evaluating managed and uncontrolled charging. The system relies on a mathematical optimization mannequin that makes use of artificial intelligence.

“If the goal is, for example, to optimize the use of electric vehicles, real-time measurement data is combined with photovoltaic forecasts to determine the best possible charging profile,” says Schütze. “The dynamic control avoids load peaks and shifts the charging process of the electric vehicle or the battery storage unit to favorable times when electricity is cheap or abundant from renewable sources.”

Contribution to vitality transition and grid stability

RAZO Power’s clever management not solely allows price financial savings for particular person households, but in addition has a broader impact: It helps to maintain the ability grid secure. The system coordinates consumption and technology of vitality in an optimum approach and thus reduces load peaks—for instance, when many households are charging their battery storage items or electric vehicles on the identical time.

“Interconnecting many households enables us not only to reduce individual costs, but also to balance power-supply variations,” explains Schütze. This creates versatile masses that may be managed like a digital energy plant: Extra solar energy is used selectively as an alternative of burdening the ability mains, and home equipment that devour a whole lot of vitality ideally run whereas renewable vitality is considerable.

This manner, RAZO Power not solely boosts a greater use of renewable energies, but in addition contributes to the steadiness of the complete vitality infrastructure.
