Pacific Engineering Corporation (PEC) Company Overview

It is possible to instantly and safely disconnect high voltage and current circuits of stationary energy storage systems (ESS) equipped with large-capacity batteries and electric mobility!

This is a device that instantaneously and safely disconnects high-voltage circuits in response to the needs of stationary power sources and electric vehicles. Our company manufactures the "Pyro Switch," which can instantaneously disconnect high-voltage and high-current circuits in large-capacity battery storage systems. 1. Instantaneous Disconnection Capability - Utilizes pyrotechnics to interrupt current in milliseconds. - Prevents the risk of electrical fires and electric shocks during accidents or electrical system anomalies. 2. High Voltage and High Current Compatibility - Models are available that can handle up to 1500V, making them suitable for large-capacity batteries. 3. Signal-Controlled Operation - Activated by signals from systems such as BMS (Battery Management System) or airbag control units. - Uses the force of pyrotechnics to move a piston and physically cut the busbar. 4. High Reliability and Environmental Resistance - Minimal degradation over time, ensuring stable operation even in harsh environments. 5. Diverse Applications - Automotive (EV, HEV, PHEV, FCV) - eVTOL (Electric Vertical Takeoff and Landing Aircraft) - Vessels - Stationary power supply systems 6. Exempt from Explosives Control Law - A safe product that is exempt from the Explosives Control Law for applications outside of automotive use.
