A Router UPS is a compact, specialized power solution designed to ensure uninterrupted connectivity for routers and networking devices. By leveraging a 12VDC, 2A power supply from an existing router adapter, it efficiently charges a 2-cell lithium-ion battery, employing a protection and balancing circuit to safeguard against overcharging and overdischarging. During power outages, the UPS swiftly switches to battery power using a boost circuit to maintain a seamless 12VDC supply to the router. An integrated switching circuit facilitates smooth transitions between the main adapter power and battery backup. The UPS includes an indicator and driving circuit to monitor battery status and control current flow accordingly. This innovative design optimizes power utilization, enhancing network reliability and ensuring constant connectivity.
The main functions of a Router UPS include:
Power Continuity: Ensure uninterrupted power supply to the router and networking devices, maintaining network connectivity even when there is a loss of mains power.
Power Protection: Protect networking equipment from power surges, spikes, and voltage fluctuations that could potentially damage the devices.
Battery Backup: Utilize a battery system to provide backup power, allowing the router to remain operational and connected to the internet during power interruptions.
Seamless Transition: Enable a seamless transition from mains power to battery power and vice versa, ensuring uninterrupted operation without any disruption in network services.
Monitoring and Management: Monitor the battery status, charging, and power levels to effectively manage and optimize the UPS system for reliable performance.
Battery Management: Manage battery charging, discharging, and health to prolong the battery life and maintain optimal performance over time.
Voltage Regulation: Provide consistent and regulated voltage to the router, preventing any voltage-related issues that could affect the router's performance or longevity.
Protection Mechanisms: Implement protective measures against overcharging and overdischarging of the battery to ensure its longevity and safe operation.
Alerts and Indicators: Provide visual or audible alerts and indicators to notify users of the UPS status, battery levels, and potential issues that require attention.
Business Continuity: Facilitate uninterrupted internet access, which is crucial for businesses and individuals reliant on consistent internet connectivity for communication, transactions, and operations.

Procedure:
Take 12VDC, 2A supply from the existing router adapter.
Divert the 12VDC supply to both the charging circuit and the switching circuit;
Channel the 12VDC supply to the charging circuit.
Charge the 2-cell lithium-ion battery with a charging voltage of 8.4VDC.
Connect the charging circuit to the protection and balancing circuit.
Ensure the protection and balancing circuit balances the cells and protects them from overcharging and overdischarging.
Implement a monitoring system within the protection circuit to detect overcharging or overdischarging of the battery.
Provide indication signals to the driving circuit for appropriate action.
Integrate the battery cells with the charging, protection, and balancing circuits.
In the event of a power outage from the 12VDC adapter, swiftly switch to battery power.
Route the battery power to the boost circuit to elevate the battery voltage to 12VDC.
Power the router using the boosted 12VDC battery voltage to ensure uninterrupted operation during power outages.
When the power is restored from the adapter, switch back to using the adapter as the power source.
Initiate recharging of the battery for future use while still providing power to the router.
