Charge Controller for Battery Protection During Interval Shooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Imaging devices experience battery deterioration due to repeated charging and discharging during interval shooting, which affects their performance and longevity.
Innovation Solution
The imaging device includes a power input unit for external power reception, a battery for powering the device, and a charge controller that prohibits charging during interval shooting when the device is in a sleep state, thereby reducing battery deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the imaging device performs interval shooting with repeated charging and discharging, then the battery can supply power continuously, but battery deterioration occurs
Solution Approach 1:
The charge controller implements periodic action by alternately charging and discharging the battery during interval shooting. The controller charges the battery when external power is available and discharges it during sleep intervals, creating a periodic charge-discharge cycle that prevents continuous discharge deterioration while maintaining power supply capability throughout the interval shooting operation
2Use of energy by moving object
If the battery is charged continuously during interval shooting, then power availability is maintained, but battery deterioration accelerates
Solution Approach 1:
The charge controller implements periodic action by alternately charging and discharging the battery during interval shooting. The controller charges the battery when external power is available and discharges it during sleep intervals, creating a periodic charge-discharge cycle that prevents continuous discharge deterioration while maintaining power supply capability throughout the interval shooting operation

AI summary
An imaging device is capable of interval shooting that allows images to be consecutively captured at predetermined image-capture intervals. The imaging device includes power input unit through which the imaging device receives power from an external device; battery configured to be charged with power received via the power input unit, and to supply power to operate the imaging device; and charge controller configured to control charging of the battery. Charge controller prohibits, under a predetermined condition, charging of the battery during the interval shooting performed by the imaging device.
