 SPARK is an effective EV charging prototype that integrates a real-time capable convolutional neural network (CNN) for occupancy detection with the RZBoard V2L. The result: a smart parking lot occupancy/EV charging experience for low cost. This system is designed to automate parking lot analysis, streaming edge compute data to your desired target: an information hub like IoT Connect, or an HDMI output. The result: improved user-experience for EV charging customers and parking lot managers.
