ESi delivers trusted engineering and forensic expertise to clients operating across the electronics industry. From product development through post-incident investigations, our multidisciplinary team supports clients with extensive technical knowledge in electrical systems, controls, embedded software, batteries, and electrical engineering.
Our team is comprised of experts with advanced degrees in electrical engineering, materials science, and chemistry, and regularly conduct rigorous evaluations of product design, system integration, code compliance, and safety protocols.
We analyze electronics-related incidents such as fires, electrical shocks, electrocutions, and battery failures and identify possible root causes such as design flaws, code violations, improper installation, or ineffective safety controls. In pre-market evaluations, our shock and electrocution hazard experts conduct failure mode and risk assessments to help clients reduce risk before products reach the public.
Our battery experts assess failures involving lithium-ion and other battery types, evaluate performance issues, and identify failure trends across product lines. Using advanced testing and modeling, we offer insight into risks across the battery lifecycle—from chemistry and internal structure to manufacturing, usage, and regulatory compliance.
Whether investigating a malfunction, evaluating system safety, or helping mitigate risks, ESi provides data-driven, technically sound insights that support decision-making, litigation strategy, and product safety.
