Project Description

This project uses IP5389_BZ mobile power SOC with a maximum output power of 100W, and BM3451TNDC-T28A 3~5-cell lithium/iron battery protection chip with balancing function, temperature protection, disconnection protection, and can be cascaded.

Reproduction of large-capacity battery products is not recommended. The project is only open source. If any property damage is caused, the author has nothing to do with it.

Project Related Functions

1. Self-charging 45W (actual measurement 45W+), the charging time is reduced by three-fifths, and the 4s 5000mAh is predicted to be fully charged within 2 hours, solving the anxiety of using electricity when going out.

2. Charging laptops, thin and light notebooks, and all-round notebooks.

3. Lithium battery balance charge indicator light.

4. Press and hold to turn on the light and start lighting.

5. PD protocol 20V output, multi-functional.

6. Too many agreements.

Project Properties

This project is made public for the first time and is my original project. The project has not won any awards in other competitions.

Project Progress

The project has been completed and is currently being tested for about two months.

Design Principles

Physical Display

PCB board.

Fast charge detection.

Charge the power bank.

Charge your laptop (MAC air)

charge mobile phone.

Design Considerations

1. Although the maximum power is set to 45W, it will appear higher than 45W during the test (65W charger test environment).

2. The production cost is about 150, so please be careful when reproducing it.

3. Before putting on the transparent cover, please make sure that both USB-C and USB-A can be charged and other functions are normal, because you can't take it off once the cover is on. Don't ask why, just ask.

4. Be sure to add a heat sink.

5. It will shut down 10% of the time during use.

6. The bracket needs to be modified during installation, as follows:

7. Failure to install NTC will cause the device to fail to start normally.
