Charging Method for Smart Shopping Carts

When a customer in a brick-and-mortar store is using a shopping cart with a tablet for assistance (i.e. a smart shopping cart), the shopping must be completed before the battery goes dead. A method is needed to charge the battery of a tablet associated with a shopping cart.

The novel contribution is a method to charge a smart shopping cart using the wheels. Each wheel contains an electric generator coil. While the user is pushing the cart, the smart shopping cart receives an electric charge.

A second novel method uses a wireless charging technique to charge the smart shopping cart with inductive energy. The system is housed below the cart basket and is associated with a wireless charging area in the floor of the cart return area . This section is connected to a battery bank, which receives the energy via a photovoltaic plank, which promotes a green energy solution.
