AI Technical Summary

Technical Problem

Ultracapacitor modules fail due to shocks and vibrations, leading to mechanical and performance issues such as damage to the housing, loosening of fasteners, and impaired performance, with existing damping solutions failing to provide adaptive stability over time.

Method used

The ultracapacitor module design includes a housing with interlocking mechanisms and adhesive connections that secure ultracapacitors, ensuring they maintain capacitance, equivalent series resistance, leakage current, operating voltage, and energy storage values within rated limits even under vibration profiles.

Benefits of technology

The module withstands vibration profiles, maintaining structural integrity and performance, passing tests for capacitance, resistance, leakage current, voltage, and energy storage, while minimizing damage and ensuring stability across a wide temperature range.

Abstract

The present invention provides an ultracapacitor module that can withstand shock and vibration, as well as a vehicle and a robot incorporating the ultracapacitor module. [Solution] The ultracapacitor module 200 has a housing and a plurality of ultracapacitors 202 housed within the housing, with at least one of the ultracapacitors fixed to the housing. The ultracapacitor module satisfies the capacitance, equivalent series resistance, leakage current, etc., specified when exposed to a vibration profile. The housing is made of metal or polymer, and the upper housing member and the lower housing member are connected by a locking mechanism.
