What is inside an EV rapid charger?

Moving products and people fuels a thriving economy. Rapid chargers are cutting our fossil fuel dependency. In just 5 minutes I will show you how they work. This is about DC rapid chargers you see in the street, powered by CCS, ChaDeMo, or NACS. My name is Janosch, and I accidentally became a rapid charging expert when I built my own electric cars (three of them!). Now I am sharing everything I know with you in short and to the point videos I wish existed when I was learning myself. There is also an app for you to learn the tech powering solar, electric cars, rapid charging and lithium batteries.

Hardware Rapid chargers are engineered to safely deliver high power at 150kW or faster: Payment Gateway: Facilitates fast and secure transactions through cards, apps, or RFID, ensuring user convenience. Relays: Precisely control power flow, turning circuits on and off during critical moments of operation. 700A Fuse: Supports high-current connections to the grid while preventing overloads, ensuring reliability. Cooling Systems: Actively dissipate heat from internal components and cables during high-power sessions. Power Electronics: Convert alternating current (AC) from the grid into direct current (DC), tailored to the vehicle’s battery. Connectors: Provide the physical link between the charger and the car, adhering to global standards like CCS, ChaDeMo, and NACS. Process Connection & Payment: The user plugs in their EV and processes payment in seconds, starting the session. Safety Check (Isolation Resistance Test): A crucial step that verifies there are no electrical faults before power flows. Power Delivery Ramp-Up: The current is increased gradually, protecting both the charger and the EV battery from damage. Feedback Loop with Battery Management System (BMS): The charger and EV communicate in real-time, adjusting current and voltage to optimize speed and safety. Charging Stops: The session ends when: The battery reaches full capacity. The user’s payment limit is reached. Safety parameters, like overheating, are triggered. Protocols The “language” of rapid charging ensures chargers and vehicles work together seamlessly: CCS (Combined Charging System): With 35,000 lines of code, this globally adopted protocol supports detailed communication for both AC and DC charging. ChaDeMo: Compact and efficient with just 1,400 lines of code, this Japanese protocol prioritizes simplicity and reliability. NACS (North American Charging Standard): Designed for North America, NACS offers a streamlined alternative to CCS, combining user-friendly connectors with high-speed charging capabilities.
