Device That Adjusts Power for Charging Multiple Devices

This 2016 patent describes a system that intelligently adjusts the power supplied to charge multiple devices, ensuring one device gets a steady charge while another can receive a variable amount.

What it covers

This patent describes a device that manages power for charging. It has a detection module that senses an incoming power signal (like current or voltage). This signal goes to a control module, which creates a control signal. An output module then uses both the input signal and the control signal to adjust the power. The key is how it handles a 'load module' which connects a 'master control device' and a 'portable electronic device' in parallel. The portable device gets an adjustable current, while the master device gets a fixed current. For example, imagine charging a laptop (master control device) and a phone (portable electronic device) from the same power source. This device would ensure the laptop gets a stable, fixed amount of power it needs to operate, while the phone's charging rate can be adjusted dynamically, perhaps to prevent overcharging or to prioritize power flow.

What it doesn't cover

• —Charging systems that only manage a single device.
• —Charging systems that do not adjust the power dynamically based on feedback or control signals.
• —Systems where both devices receive a fixed amount of power.
• —Systems where both devices receive an adjustable amount of power.
• —Charging methods that do not involve parallel connection of devices.

The clever bit

The innovation lies in the ability to simultaneously manage different power requirements for multiple devices connected in parallel. It intelligently dedicates a fixed, stable power stream to a primary device while allowing for dynamic, adjustable power delivery to a secondary device, optimizing the charging process for both.

Why it matters

This patent addresses the growing need for efficient power management in a world with many connected devices. As more electronics require charging, systems that can intelligently distribute power become crucial for user experience and device longevity. This technology is relevant to power adapters, charging stations, and even in-vehicle charging systems.
