The dynamic load balancing EV charger can detect used power of the main circuit and adjust its charging current accordingly and automatically, allowing for energy savings to be realized. Our design is to use the current transformer claps to detect the current of the main circuits of household, and users needs to set the max loading current when install the dynamic load balancing box via our smart life App. User also can monitoring the home loading current via the App. The dynamic load balancing box is communicating with our EV Charger wireless via LoRa 433 band, which is stable and long distance, avoiding the message lost.
