Technology Overview
Zolair Energy Solutions leverages cutting-edge battery technologies specifically optimized for the African market. Our proprietary battery systems and swapping infrastructure are designed to overcome the unique challenges of operating in Nigeria and other emerging markets, including unreliable grid electricity, high temperatures, and varied road conditions.
Core Technologies
Zinc-Air Battery Technology
Our primary e-tricycle power system uses advanced zinc-air battery technology, offering superior energy density, safety, and cost-effectiveness compared to traditional lithium-ion batteries. These batteries are specifically designed for the swapping model, with quick-connect terminals and robust casing for thousands of swap cycles.
Sodium-Ion Battery Technology
For our stationary storage at swapping stations, we employ sodium-ion battery technology. These batteries provide excellent thermal stability in hot climates, use abundant and low-cost materials, and offer exceptional cycle life for grid-buffering applications.
Battery Swapping Infrastructure
Our proprietary swapping stations enable a complete battery exchange in under 60 seconds. The system includes automated authentication, battery diagnostics, and cloud-connected inventory management to ensure optimal battery availability and performance.
Solar Integration
Each swapping station incorporates solar PV panels with our sodium-ion storage, creating microgrids that can operate independently of the main power grid. This ensures reliable operation even during power outages and reduces operational costs.
