Service examples
Forensics
Battery failure investigation
We provide findings and solutions to product failures, both in the lab and in the field. Unknown events often cause production to stop ship or recall and we pride ourselves in providing clear answers in these tough times.
01
System failure analysis
Fire investigators are rarely trained subject matter experts in battery pack failures. This often results in the battery being blamed, even if it were only involved by not causality. We approach forensic analysis with the expertise needed to prove your product's innocence, or explain root causality. Our presence helps identify and protect against common battery forensics mistakes or overlooked details during analysis.
02
Corrosion mitigation
Many batteries in the wild will face condensing humidity cycles, corrosive road salt droplet spray, dilute acid gas exposure, and more. Standards like IP67 or IP69 lead to false positives of environmental integrity. We have developed proprietary testing solutions to produce accelerated and repeatable quantification of environmental risks to performance and safety.
03
Testing
Test planning
We offer test plan creation, audits, and guidance. We have a library of proven effective internal tests and custom test fixtures to encompass every type of electrical test, thermal behavior, environmental ruggedness, and cell or pack safe and unsafe operating conditions.
01
Component validation
We validate component operating parameters under ideal conditions to find real-world bounds for failure. After individual testing components are assembled into representative test conditions to compare operational performance with individual test data.
02
Cell safety
Our calorimeter is the largest and most capable ARC used in thermal runaway quantification. This enables rapid cell development to improve safety and energy release mitigation.
03
Material science
Research and development
We perform verification of specifications to confirm solutions for battery components and materials. Our R+D continuously feeds materials and processes into the industry to improve readily available products.
01
Polymeric material application
Adhesives and encapsulation potting materials require specific preparation methods and unique preparation experience. Through adhesive joint testing we’ve created optimum processes for bonded joint challenges.
02
Material compatibility
We provide testing and guidance of long-term material behavior properties, including dielectric breakdown and ionic migration degradation.
03
Consulting
Design reviews and guidance
We offer system and design reviews to improve product lifetime, reliability, and mitigate design issues before they become a problem.
01
Component selection
Our team is experienced in power component reliability and performance. When selecting a part EG can create design specifications and will assist in sourcing, manufacturing, and quality control.
02
Secure cell supply
We provide technical design guidance and testing to pass the feasibility and risk assessment gates presented by cell providers before negotiating commercial contracts.
03
Specialized equipment
Cell interconnect methodology
Our years of experience testing cell interconnects have resulted in a matrix of proprietary information that we use to inform our decisions for a specific project. Safe and reliable interconnects that eliminate cell damage are mission critical for all battery systems.
01
Equipment specifications and vendor support
We provide guidance on tool specifications, techniques, and skills needed to achieve success for your project. Our team has tested equipment and tooling for battery, motor, and related validation manufacturing.
02
Battery production line repeatability, quality, process safety audits
Our team has been instrumental in establishing successful battery manufacturing lines globally for our clients. Our team serves as an asset for new lines or during existing established lines looking to streamline and reduce manufacturing fall-out.
03
Cell services
Cell characterization
We specialize in cell development, utilizing the latest in testing methodology to achieve our goals. We have extensive experience with forced temperature gradient cycling, thermal analysis, destructive, and non-destructive testing.
01
Vacuum or reduced atmosphere specialty testing
Our custom vacuum test chambers provide aircraft and space applications with electrical, thermal, and safety validation under application representative atmospheric conditions.
02
Design services
Our team leverages thermal runaway data along with thermally-clamping materials to enable the lowest number of iterative development steps to meet our client’s safety and performance objectives.
