Battery Level Indication For An Aeorosol Generating Device

Patent No. EP4032419 (titled "Battery Level Indication For An Aeorosol Generating Device") was filed by Japan Tobacco on Jan 26, 2021. The application was issued on May 7, 2025.

Patent Summary

Battery level indication for an aerosol generating device like an e-cigarette that shows how many consumable cartridges can be fully used with the remaining battery charge. This helps users gauge how many puffs they can get before recharging. The indication is calculated by dividing the remaining charge by the average amount needed to vape a cartridge. The result is rounded down to whole numbers. The indicators on the device are illuminated based on this calculation. If less than half the total indicators can be lit, they're all green. If half or more, some are green and others are red. This indicates a partial charge level.
