Charging Station, Arrangement with Multiple Such Charging Stations, and Method for Operating Such a Charging Station

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a versatile charging station (charging point) for electric vehicles and various electrical resources. It not only allows for the bidirectional charging and discharging of vehicles but can flexibly connect to different types of energy sources (like photovoltaics and batteries) and loads, integrating them efficiently into a local smart grid. The charging station employs advanced power electronics to switch between different operating modes (DC/DC, rectifier, inverter) and can coordinate with multiple such stations for optimized grid management.

Use CasesContent extracted from patent full text and abstract with AI.

• Charging electric vehicles at home, in businesses, or public parking areas using AC or DC connections.
• Integrating stationary energy storage (batteries) or vehicle batteries into the local energy grid for energy balancing or backup power.
• Connecting local renewable energy sources (e.g., solar panels) directly to charging infrastructure for clean energy usage and storage.
• Supporting smart grids by flexibly distributing, storing, or consuming energy through the charging stations, including vehicle-to-grid (V2G) and grid-to-vehicle (G2V) scenarios.
• Providing efficient charging and discharging for a variety of electric mobility devices and work machines (e.g., e-bikes, small tractors, lawnmowers, recreational vehicles).
• Reducing peak grid loads by smart demand management, leveraging distributed storage in vehicles or batteries.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables highly flexible energy management and distribution within local smart grids, optimizing use of renewable sources and storage.
• Supports bidirectional energy transfer, allowing electric vehicles and devices to both draw from and supply electricity to the grid (V2G).
• Allows efficient integration of various energy sources and consumers, including different voltages and grid topologies (AC/DC, high and low voltage).
• Increases the utilization and value of mobile and stationary batteries, reducing waste and providing financial incentives for electric vehicle owners.
• Enhances resiliency and efficiency of local power networks, lowering dependency on centralized power sources and reducing losses.
• Can facilitate greener, more sustainable energy use by prioritizing renewables and intelligent energy distribution based on demand, pricing, and environmental signals (CO2, weather, price data).
• Scalable to networks of multiple charging stations for greater capacity, redundancy, and optimization.

Patent Abstract

The invention relates to a charging point (1) comprising a power electronics converter module (2) for converting electrical energy, a controller (3) for controlling the converter module (2), a direct voltage bus (4), a distribution module (7), one or more direct voltage connection lines (5) and one or more alternating voltage connection lines (6). The converter module (2) is electrically interconnected between the direct voltage bus (4) and the distribution module (7). The distribution module (7) is designed to connect or disconnect the individual connection lines of the one or more direct voltage connection lines (5), or of the one or more alternating voltage connection lines (6) to the converter module (2) or from the converter module (2). The converter module (2) can be controlled by the controller (3) such that the converter module (2) can work as a DC-to-DC converter, or alternatively as a rectifier or inverter.
