XEYAR ADVANTAGE
The Problem: Why Grid-Connected Chargers Fall Short
The EV charging infrastructure crisis isn’t about charger availability — it’s about grid availability. Most commercial and retail sites simply don’t have the electrical capacity to support high-power DC fast chargers. Installing a 240–360 kW charger at a gas station, shopping center, or multifamily property requires utility upgrades that can take 12–24 months, cost $150,000–$1,000,000+, and still leave operators subject to demand charge penalties that make economics unviable.
The result: a global gap between EV adoption (17 million+ EVs sold in 2024, projected 40%+ of all new cars by 2030) and the charging infrastructure required to support them. XEYAR’s buffer architecture eliminates this bottleneck entirely.
XEYAR ADVANTAGE: Buffered EV Charging
The XEYAR Solution: Buffer Architecture
A XEYAR battery-buffered charger separates grid draw from charger output. The integrated energy storage module — supercapacitor or sodium-ion — continuously draws at the site’s available power level (as low as 50 kW), accumulating stored energy between charging sessions. When an EV connects, the system instantaneously releases up to 240 kW or 360 kW — far exceeding what the site’s grid connection alone could support.
This architecture eliminates the need for utility upgrades, reduces peak demand charges by up to 25%, enables deployment at virtually any existing commercial site, and supports seamless integration with rooftop solar or on-site wind generation for a truly grid-independent charging hub.

SuperCap EV - Supercapacitor-Buffered Chargers
XEYAR’s SuperCap EV series uses electrostatic supercapacitor buffer modules with over 50,000 charge-discharge cycle life — providing 20+ years of reliable buffered charging without degradation. The air-cooled design requires no complex thermal management, dramatically reducing maintenance costs and complexity. The proprietary AI-based energy management system dynamically balances grid input, buffer state, and renewable generation in real time.
4x Daily Cycling
SuperCap modules support up to 4 full charge-discharge cycles per day — vs. 0.5–1x for lithium systems — maximizing charger revenue potential per installed unit.
Extreme Temperature Operation
Operates from -40°C to +65°C without active cooling or heating. Lithium-based buffers require thermal management below -5°C, incurring additional cost and complexity.
Zero Thermal Runaway
No lithium, no cobalt, no fire risk. SuperCap technology is not subject to lithium-ion thermal runaway regulations — no special fire extinguishers, no insurance surcharges.
AI Energy Management
Intelligent algorithms optimize off-peak trickle charging, peak-shaving discharge, and renewable integration to minimize electricity costs and maximize net income per session.
Virtually Zero Maintenance
Self-monitoring CMS platform requires no periodic maintenance. All modules are field-replaceable without interrupting operations.
20-Year Warranty
Backed by a 20-year product and performance warranty — more than double the typical 10-year lithium charger buffer warranty — ensuring long-term investment protection.
Na-ion EV — Sodium-Ion-Buffered Chargers
For operators who require higher energy density per installation footprint or prefer a proven electrochemical buffer technology, XEYAR’s Na-ion EV series provides the same grid-independent, ultra-fast charging performance through sodium-ion battery chemistry. With the same 240 kW and 360 kW output configurations, dual-port CCS/CHAdeMO compatibility, and AI energy management, Na-ion EV chargers deliver identical customer-facing performance with distinct technical characteristics suited to certain climates, deployment footprints, and regulatory environments.
Na-ion buffers recharge in 30–60 minutes, support 80%+ depth of discharge, and operate across -40°C to +60°C. Non-hazardous material certification (CNAS) simplifies logistics to remote or international deployment sites. UL1973, UL9540A, and 2013/56/EU certifications ensure compliance across North American and European markets.
