Abstract
A wireless device charging pad (WDCP) that is laid on a surface such as a tabletop and will wirelessly charge a device such as a wireless phone or table computer that is placed on the pad. The WDCP has two substrates, with a charging system sandwiched between the substrates. The charging system comprises a board, batteries each with a charge and discharge protection circuit, boost converters, and an external battery charger that receives power from a power source such ad home or business utility power. The battery charger plugs into the WDCP and provides power to the charging system. Once the charging system is charged, a person simply places their wireless device on the pad, which then automatically wirelessly charges the wireless device.
Claims22
A wireless device charging pad comprising:
- a first substrate configured with
- an upper surface,
- a lower surface,
- a second substrate configured with
- an upper surface,
- a lower surface,
- attachment means for securing the first substrate to the second substrate,
- a charging system configured between the first substrate and second substrate, and comprising:
- at least one charging coil,
- a multi coil charging board,
- at least one battery,
- a charge and discharge protection circuit, and
- a boost converter.
A wireless device charging pad comprising:
- a first substrate configured with
- an upper surface,
- a lower surface,
- a second substrate configured with
- an upper surface,
- a lower surface,
- attachment means for securing the first substrate to the second substrate,
- a charging system configured between the first substrate and second substrate, and comprising:
- a plurality of charging coils, with each coil configured as a primary winding of a transformer that is created between the charging system and a wireless device,
- a multi-coil charging board that interfaces with, operates and controls the charging coils,
- a plurality of high density lithium ion batteries, each having a charge and discharge protection circuit that protects the battery from over charging, the batteries configured to power the charging coils and multi-coil charging board,
- a plurality of boost converters, with one boost converter incorporated into one of the charging coils, the boost converter correcting for a difference in voltage between the battery output voltage of 3.8 volts and the multi-coil charging board voltage input requirement of 5-volts, and
- an external battery charger that is connected to an external power source, and comprises a cable extending from the battery charger and having a male plug at a distal end, the male plug inserted into a battery charging female plug connected to the charging system, once the wireless charging pad is charged, a wireless device having wireless charging capability is placed on the upper surface of the second substrate above the charging coils, thereby, charging the wireless device.
