Solution Overview
Problem
Existing backup systems for vehicles are often expensive, complex, prone to malfunction, risk voiding warranties, and have limited battery sizes, requiring manual maintenance and temporary connections.
Innovation Solution
A smart battery backup system with a lithium-ion battery and controller that automatically jump-starts and self-maintains, using momentary switches and a charging switch to connect the lithium-ion battery to the main battery or an external power source, facilitating permanent installation and reducing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing backup systems use manual connection and disconnection of battery cables, then the system can be simple in structure, but the ease of operation deteriorates due to repeated manual intervention
Solution Approach 1:
The system automatically monitors battery charge states and performs charging operations without user intervention. The controller continuously checks the charge state of both the main battery and backup battery, automatically initiating charging when the backup battery needs power, eliminating the need for users to manually connect or disconnect cables.
2Device complexity
If existing backup systems require regular manual charging, then the system structure remains simple, but the loss of time increases due to frequent maintenance interruptions
Solution Approach 1:
The system continuously monitors battery charge states and automatically performs charging operations when needed. The controller checks the charge state of the backup battery and main battery continuously or periodically, ensuring the backup battery is always ready without requiring scheduled manual maintenance, thus eliminating time loss to maintenance interruptions.
3Device complexity
If existing backup systems use temporary cable connections, then the system can be portable and simple, but the reliability deteriorates due to connection issues and potential malfunctions
Solution Approach 1:
The system integrates the backup battery, controller, and connection terminals into a single unified unit. This permanent integration eliminates the need for separate portable jump packs and external cables, reducing connection points and potential failure modes while improving overall system reliability.
4Device complexity
If existing backup systems are designed with limited battery sizes, then the device remains compact and simple, but the adaptability worsens due to vehicle-specific limitations
Solution Approach 1:
The system is designed to work with various vehicle types by monitoring the charge state of the main battery and automatically initiating charging when needed. The controller can adapt to different vehicle electrical systems and battery configurations, making the system versatile across multiple vehicle platforms rather than being limited to specific models.

Data Source
AI summary
In an example, a smart battery backup system is disclosed. The system is configured to be installed on or within a vehicle and connected to a main battery of the vehicle. The system includes a housing, a lithium-ion battery disposed at least partially within the housing, and a controller disposed at least partially within the housing and including a set of momentary switches. The controller is configured to jump start the main battery using the lithium-ion battery. The controller is also configured to maintain the lithium-ion battery such that, based on a charge state of the lithium-ion battery and a charge state of the main battery, the lithium-ion battery is charged using the main battery.
