CORE TECHNOLOGIES
Second-use Battery Technology
Second-use not second-life EV batteries with embedded BMS control and integration of OEM cooling system and HV connections
Independent Battery Architecture
Fully bi-directional energy flows, enhanced reliability with no single point of failure, ensuring continuous operation and ease of maintenance
Bi-directional Power Electronics
High efficiency wide bandgap technologies with advanced control including synchronous and asynchronous grid forming capability

"Second-use" EV Batteries
We source nearly new batteries from a range of partners including fleets, insurers and car manufacturers. We have proprietary technology to determine battery health and safety for repurposing. EV batteries possess an average 94% State of Health (SoH) offering a long life similar to new batteries but with a 60% lower carbon footprint.
Total Integration, Maximum Safety
Unlike other BESS, Allye's systems repurpose the entire battery pack including the BMS, cooling system and the High-Voltage (HV) cables from the vehicle. This maintains pack integrity and re-uses the BMS developed specifically for that pack, chemistry and architecture so our MAX systems operate within the original parameters set by the OEM

Green Performance Advantage
Environmental and economic advantages without performance compromise

Power On:
Bi-Directional Battery Intelligence
The architecture of each MAX comprises fully independent battery packs, each connected in parallel with a common AC bus that enables true bi-directional energy management.
This has many benefits and allows the battery to work smarter, to improve efficiency, reliability and lifetime. There is no single point of failure, ensuring continuous operation and ease of maintenance.
ARCHITECTURAL FLEXIBILITY

Any Make & Model
Mix and match different battery packs from different OEMs in a single system, maximising our ability to source EV packs, in any configuration

Any Chemistry
Combination of different chemistries to take advantage different characteristics depending on application and environmental conditions

Any State of Health (SoH)
Elimination of the challenges of balancing different SoH across packs through independent control and convergent cycling of packs

A Power Revolution for Energy Resilience
Advanced power electronics and control software delivers seamless transition between grid and island modes through synchronous grid-forming technology to create and regulate grid voltage and frequency independently or in coordination with other sources. Three-phase asynchronous grid-forming capability is currently in development.
Our smart inverter-based solutions provide crucial real and reactive power for voltage control, while our battery-backed systems deliver synthetic inertia to grid networks. This synthetic inertia is essential for supporting grid stability, particularly given the variable nature of renewable energy sources
