problems
This item is a very good concept, unfortunately facing problems hereunder. Functioning very badly and easily out of order:
- Battery dies easily. – Need better battery and a battery protection fast charging cable with battery protection management system.
- Take too long time to charge the battery to the power level to start boiling the water. – Need to enable plug & play.
- PCBA is badly designed, malfunction too easily. – In advanced PCBA with in advance industrial protocol is needed
we have solutions
A. Features to enable.
- Plug and Play
- Minimum: 20 Bars
- 5V (OR 24V, 48V???)
- 100W (OR 240W???)
- Water temperature: 96°C
- 7800mAh Heating & Extraction [Battery Life = Battery Capacity (mAh) / Load Current (mA)] https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-battery-life
{Consider using bigger battery e.g.: Id: 40152 Other common: 40152s Typical capacity (mAh): 15,000mAh Dia: 40mm Length: 152mm Comments LiFePO4 3.2V. Largest cylindrical LiFePO4 cells. Height including the screw terminals: 167mm [citation needed]}
B. Build a new fast charging cable with battery management system to protect and manage the coffee maker’s battery.
- 100W, 5V (2 outs) (OR 240W, 48V, 5A charging cable).
- Charging time can be set with a timer, alarm goes on when time is up. And the charge is off immediately and automatically. https://youtu.be/WywxQkPJtqg
- Auto off charge when battery is fully charged.
- Auto off charge when thermistor sense battery is overheated.
