, Description:
FIELD
The present disclosure relates to a charging apparatus.
BACKGROUND
Conventionally, a charger is used for charging a battery of a device. For charging the battery, a handheld device needs to be connected to an AC mains outlet via the charger. However, wired charging approach limits the mobility of the handheld device during charging.
Alternatively, a power bank is used to charge the handheld device for achieving mobility. However, the power bank requires external charging periodically to maintain its SOC (State of charge).
Further, different techniques are used to charge the handheld device. One of the techniques is to use a piezoelectric unit. In a typical implementation, the piezoelectric unit is installed in a shoe. When a pressure is applied on the sole of the shoe while walking, the piezoelectric unit converts the physical energy created during walking into electricity, which is then further used for charging the handheld device. However, the pressure applied on the sole of the shoe may vary from surface to surface, thereby not providing a constant rate of generation of electricity for charging the handheld device.
There is, therefore, felt a need for a charging apparatus that alleviates the aforementioned drawbacks of the conventional systems.
