GAC Humanoid Battery Swap Patent

🔑 Enhanced Key Takeaways

• •The patent (CN119351234A) specifically details a 'cooperative' mechanism where the robot's mobile chassis aligns with the swap station's positioning sensors to ensure sub-millimeter precision during the battery extraction process.
• •GAC's strategy involves integrating this battery swap infrastructure into their existing 'GAC Energy' ecosystem, potentially allowing humanoid robots to utilize the same power-swapping network currently deployed for GAC electric vehicles.
• •The system incorporates a proprietary 'energy-management handshake' protocol that allows the robot to communicate its remaining state-of-charge (SoC) and health status to the swap cabinet before arrival to optimize charging cycles.

🛠️ Technical Deep Dive

• •Mechanical Interface: Employs a multi-point locking mechanism with electromagnetic actuators to secure the battery pack during high-vibration movement.
• •Communication Protocol: Utilizes CAN-FD (Controller Area Network Flexible Data-rate) for low-latency communication between the robot's BMS (Battery Management System) and the swap station.
• •Positioning System: Integrates LiDAR and visual servoing (using the robot's onboard cameras) to achieve precise alignment with the mobile swap cabinet's mechanical arm.
• •Power Density: The battery pack design focuses on high-C-rate discharge capabilities to support the high-torque requirements of humanoid actuators.
