[0016] Example 1:

[0017] Please see Figures 1-11 The present invention provides a high-power Bluetooth charger, comprising a charger body 1, a circuit mechanism 2 fixedly connected inside the charger body 1, and a fan provided on the front side of the circuit mechanism 2.

The high-voltage filter capacitor 23 helps to stabilize the input voltage.

[0019] A resonant capacitor 24 is soldered to the top right side of PCB board 21, a fan socket 25 is soldered to the top left front end of PCB board 21, a status indicator light 26 is soldered to the top left end of PCB board 21, and an NTC temperature sensor 27 is soldered to the top left end of PCB board 21. The status indicator light 26 is used for warning purposes.

[0020] A DC output terminal 28 is soldered to the top left end of PCB board 21. A Bluetooth board 29 is soldered to the center of the top left end of PCB board 21. An output relay 210 is soldered to the rear left end of PCB board 21. An aluminum heat sink 211 is soldered to the rear top end of PCB board 21. A transformer 212 is soldered to the center of the top of PCB board 21. A power MOSFET 213 is soldered to the right front end of aluminum heat sink 211. A Bluetooth antenna 214 is soldered to the left bottom end of PCB board 21. A Bluetooth chip 215 is soldered to the rear bottom end of PCB board 21. The Bluetooth chip 215 facilitates A / D conversion of MOD voltage.

[0021] The Bluetooth chip 215 has a crystal oscillator 216 on the front side. The PCB board 21 has a download and debugging port 217 fixed by solder on the bottom front side. The PCB board 21 has a high-power charger connection port 218 fixed by solder on the bottom right end. The resonant capacitor 24 is located to the left of the high-voltage filter capacitor 23. The high-voltage filter capacitor 23 is located to the left of the AC input terminal 22. The fan on the front side of the circuit mechanism 2 is connected to the fan socket 25 via a cable. The NTC temperature sensor 27 is located in front of the status indicator light 26. The status indicator light 26 is located to the right of the DC output terminal 28. The crystal oscillator 216 is fixed by solder on the bottom of the PCB board 21.

[0022] The working principle of a high-power Bluetooth charger based on the above embodiments is as follows: First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation. Second, after the charger is connected to the AC input terminal 22, the high-voltage filter capacitor 23 stabilizes the input voltage, the transformer 212 begins voltage conversion, and then the Bluetooth board 29 starts. The MOD voltage is converted by the PB6 pin of the Bluetooth chip 215 to identify the original charger model, maximum output voltage, and current. If there is no data for the MOD voltage, the default parameters stored locally on the Bluetooth board 29 are called. When the user connects the DC output terminal 28 of the charger body 1 to the battery, the Bluetooth board 29 detects the polarity through the PA6 pin (RE pin). If it is high, it means that the positive and negative terminals of the battery are reversed, and the status indicator 26 is immediately controlled to "blink red and green lights" as an alarm, without triggering the output relay 210. At the same time, the Bluetooth board 29 detects the polarity through the PB0 pin (IG pin). The system checks for overcurrent. If the signal is high, the output relay 210 is disabled to prevent damage to the battery or charger body 1. If the polarity is normal and there is no overcurrent, the Bluetooth board 29 controls pin PB9 (RC pin) to activate the output relay 210, connecting the charger body 1 and the battery charging circuit. Then, the Bluetooth board 29 detects the ambient temperature via pin PA5 (NTC_2) and the temperature of the power MOSFET 213 and transformer 212 via pin PA8 (NTC_1). If the temperature is too high, it controls pin PB8 (FC pin) to activate the front fan of circuit mechanism 2, driving the fan for heat dissipation through fan socket 25. Then, the Bluetooth board 29 generates a PWM square wave via pin PA4 (V_PWM), which is filtered to generate a DC voltage, controlling... The charger body 1 outputs voltage, which is then used to generate a PWM square wave via pin PA1 (I_PWM) to control the output current. Simultaneously, pins PA7 (V_ADC) and PA3 (I_ADC) collect the output voltage and current in real time. If the voltage / current exceeds the set threshold, V_PWM / I_PWM is immediately adjusted, or charging is paused. During charging, the Bluetooth board 29 continuously collects parameters such as voltage, current, charging time, ambient temperature, number of charging cycles, and charging capacity. This real-time collected and stored data is uploaded to a backend server via Bluetooth connection to a mobile app. The charging mode is changed by receiving settings from the mobile app and the backend server, and the backend server determines the battery's health based on the charging parameters. The charging process, including whether thermal runaway occurs, is displayed on the mobile app. When V_ADC detects that the battery voltage has reached the full charge threshold and I_ADC detects that the current has dropped to the threshold, the Bluetooth board 29 determines that charging is complete, controls the RC pin to disconnect the output relay 210, stops charging, and simultaneously controls the status indicator 26 to remain on, indicating to the user that charging is complete. When abnormal protection of the charger body 1 is required, when a high level is detected in VH (PB3 pin), the Bluetooth board 29 reduces the output current to avoid overloading the charger. When NTC_1 detects a high temperature, the Bluetooth board 29 first reduces the current; if the temperature still rises, charging is paused, and the front fan of the circuit mechanism 2 continues to run until the temperature drops. When a high level is detected in IG (PB0 pin),Immediately disconnect output relay 210, status indicator 26 flashes as an alarm, and an overcurrent alert is pushed to the APP.

[0023] This utility model provides an improved high-power Bluetooth charger, which includes a Bluetooth board 29. The Bluetooth board 29 is used to control the charger body 1 to charge the battery, collect and store parameters such as voltage, current, charging time, ambient temperature, number of charging cycles, charging capacity, and charged energy during the charging process, and upload the real-time collected data and stored data to the backend server via Bluetooth connection to a mobile APP. It also receives settings from the mobile APP and the backend server to change the charging mode of the battery. The backend server judges the battery health and whether thermal runaway occurs during the battery charging process based on the charging parameters and displays the results on the mobile APP.
