Removable Battery Pack Jump Starter With Supercapacitor Boost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle battery jump starters are limited by internal power sources that may not always be fully charged, especially in emergencies, and they often rely on AC mains power for charging, which may not be readily available.
Innovation Solution
A vehicle battery jump starter powered by a removable and rechargeable battery pack, which includes a battery pack interface, a power boost circuit with energy storage devices, and electrical cables with terminal clamps, allowing the jump starter to be charged and used to jump start a vehicle battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If AC mains power is used to charge the jump starter, then the power source can be recharged, but AC mains power is not always readily available in emergencies
Solution Approach 1:
The power input module is designed to accept multiple charging sources including AC mains power, vehicle battery, and power bank, allowing the jump starter to be recharged in various conditions. The controller selectively manages power input from different sources based on availability and suitability for charging the power storage module.
2Reliability
If a bank of supercapacitors is used to charge the vehicle battery, then some charging capability is provided, but the supercapacitors alone may not always be sufficient to jump start the vehicle battery
Solution Approach 1:
The system combines a power storage module (supercapacitors) with an optional removable battery pack to create a hybrid power source. The controller manages power flow from both the power storage module and battery pack to the vehicle battery, providing sufficient power for both gradual charging and high-power jump starting when needed.
3Adaptability or versatility
If a removable battery pack is used to power the jump starter, then versatility is enhanced, but the battery pack may not provide sufficient current without an energy storage device
Solution Approach 1:
The power storage module (supercapacitors) acts as an intermediary between the removable battery pack and the vehicle battery. The battery pack charges the power storage module, which then provides high-current discharge to the vehicle battery during jump starting, enabling the low-power battery pack to enable high-power operation through the energy-dense supercapacitor intermediary.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a versatile and reliable means to jump start a vehicle battery, as the removable battery pack can be used to charge the power boost circuit, enabling sufficient current to start a vehicle even when AC mains power is unavailable.
Implementation Method 1
a power boost circuit including one or more energy storage devices

AI summary
A vehicle battery jump starter that is powered by a removable and rechargeable battery pack, such as a battery pack used with various hand-held power tools. The battery pack removably connects to a vehicle battery jump starter and can be selectively used to charge a power boost module within the vehicle battery jump starter. The power boost module includes, for example, a plurality of supercapacitors or lithium polymer battery cells. The power boost module in combination with the battery pack 100 can be used to jump start a vehicle battery.
