DCLadung

DCLadung is a term used in German-language technical contexts to describe the charging of a device or energy storage system using direct current (DC) rather than alternating current (AC). It is commonly applied to settings where the battery or storage unit can accept a high-power DC input, often to achieve faster charging or to bypass onboard AC-DC conversion.

In practice, DCLadung refers to the process where a DC charging source delivers a configured DC voltage and current directly to the battery or energy storage system. This approach is widely used in electric vehicle charging and in stationary battery storage, where a dedicated DC charger or a DC fast-charging station supplies power through a DC connector. The receiving end—such as the battery management system (BMS) of an EV or a storage system—controls charging parameters, cell balancing, state of charge, and thermal management.

Standards and interfaces for DC charging vary by region. Common examples include CCS (Combined Charging System) in many markets, GB/T in China, and CHAdeMO in other areas. Communication protocols, such as ISO 15118 or vendor-specific sequences, coordinate charging power and safety between the charger and the vehicle or storage system. Real-world implementations must ensure proper voltage and current matching, fault protection, and robust cooling to handle high-power operation.

Safety considerations for DCLadung include managing high current, preventing thermal runaway in lithium-ion cells, ensuring cable and connector integrity, and providing appropriate protection devices and emergency shutoffs. While the term DCLadung appears mainly in German-language documentation, it generally denotes the category of charging that occurs via direct DC power.
