The EPiC Advantage
Our Electric Propulsion Ion Core (EPiC) Ecosystem makes airborne mobility the preferred mode of mobility. The integrated energy ecosystem provides a comprehensive solution, with modules integrated into flexible energy storage systems. This enables fast-charging energy and grid buffering services to the aircraft operators at a competitive rate.
Modular Approach
The EPiC System is designed to be adaptable to a wide range of applications and uses, allowing customers the flexibility needed to innovate and design future generation mobility solutions while leveraging economies of scale and rapid product support. Battery configuration may be modified to accommodate a wide range of voltage, power and energy requirements.
In 2021, EP Systems released EPiC 1.0. It addressed some of the most prevalent roadblocks to advanced air mobility – including safety, cost, weight, and infrastructure. This lightweight, high-power system offers an impressive 60 minutes of usable flight time with 30 minutes of reserve.
In 2024, EPiC 2.0 advances the concept even further. The trailblazing energy storage system provides 90 minutes of usable flight time with 30 minutes of reserve, opening up a host of new applications for electric aircraft. EPiC 2.0 is currently undergoing its safety of flight development and is scheduled to become available for flight in early 2025. EPiC 2.0 is a drop-in replacement for the EPiC 1.0 TSO system so it’s easy to upgrade.

Components
EPiC Propulsion Battery System
- Motor
- MSC
- BPMU
- Charger
- Cooling
- Modules
- Thermal Management
- Mid-Point
Battery Power Management Unit
The BPMU monitors and reports system status, communicating with each component in the system and enacting controls as directed by the operator. Multiple safety features have been included in the design of the BPMU, including Isolation Detection, system charging self-protection, and numerous status warnings and messages relating to safe operation of high voltage propulsion batteries.
Midpoint Disconnect
The MPD contains an electrical contactor and the system high voltage fuse. The fuse may be manually removed to reduce effective battery string voltage for safe handling and maintenance operations.
Battery Module
Each Battery Module monitors cell voltage and temperature, and enacts passive balancing to ensure that string voltage remains balanced and optimized.
