Battery-buffered cluster chargers built on the patented XEYAR shared DC bus architecture. Add high-power EV charging to any existing 100 A service — no transformer upgrade, no 18-month utility wait, and a battery that earns recurring VPP grid revenue from multi-cycle arbitrage.
The XEYAR patent defines a shared DC bus where grid input and battery discharge are simultaneous and additive — not sequential. That single architectural choice is why a 100 A service can drive 720 kW of EV charging.
A 100 A standard service feeds the bidirectional PCS (UL 1741), which converts AC to DC for the shared bus. 24 kW for L2 systems · 83.1 kW for DCFC — flat, continuous, never spiked.
The DRACO Energy Storage System sits on the DC bus and absorbs/releases on demand. Two chemistry options: SuperCap (3C, 500K+ cycles, 316 yr life) or Na-ion RockNa (5C, 20K cycles, 31% cheaper per kWh).
Charger power = grid + battery simultaneously. eMÖTEN CMS guarantees 50% of nameplate per active port — double the industry-standard 4-car equal share. NEC 625.42(A) certified.
The shared DC bus architecture, energy management algorithms, multi-port distribution logic, and battery sizing methodology are protected by XEYAR Patent (PPA Rev.12 / CIPO FIG.1). Licensed exclusively to MÖTEN evfc — not available from any other manufacturer.

Common questions about XEYAR-buffered cluster chargers, the patented architecture, certifications, and what to expect on your site.
A battery-buffered EV charger includes an on-site energy storage system that sits between the electrical grid and the chargers. Instead of pulling all the power directly from the grid (which would require a much larger electrical service), the system stores energy in a battery and releases it when EVs are charging.
This is fundamentally different from a conventional charger because it lets you deliver high charging power on a small grid connection. A regular 240 kW DC fast charger needs a 240 kW grid connection. Our XEYAR-buffered SPHINX240-B121N-4C cluster delivers 4 × 240 kW from a 100 A standard service — because the battery handles the peaks and the grid trickle-charges the battery between sessions.
In most cases, no transformer upgrade is required. XEYAR-buffered clusters are designed to run on a standard 100 A service (24 kW continuous for L2 systems, 83.1 kW for DCFC systems on 3-phase 480V). The DRACO ESS handles the difference between grid input and charger demand.
This typically avoids the cost of a major utility transformer upgrade and the 6–18 month wait time for utility-side construction. We strongly recommend a site assessment to verify your existing service capacity, panel headroom, and utility tariff — book one through our sales engineering team.
The DRACO ESS uses its bidirectional Power Conversion System (PCS) to participate in Virtual Power Plant (VPP) energy arbitrage. The battery charges from the grid during off-peak hours (typically 10 PM–4 AM) and exports back to the grid during peak hours (2–6 PM) — earning the local off-peak/peak spread per kWh.
Revenue scales with battery capacity, chemistry, and local utility rates. SuperCap (3C) achieves 6 cycles per 4-hour export window; Na-ion (5C) achieves 10 cycles. There is no daily cap — only the cycle life of the battery. For local VPP revenue figures, see your country page or run the calculator above.
The XEYAR patent (PPA Rev.12 in the United States, CIPO FIG.1 in Canada) protects the Modular Battery-Buffered Clustered EV Charging System, including the shared DC bus architecture, the energy management algorithms that orchestrate grid + battery + chargers simultaneously, and the multi-port distribution logic. Inventor: Salim M. Moten. Patent vehicle: XEYAR Ltd.
MÖTEN evfc holds the exclusive license to manufacture and sell systems using this architecture. No other manufacturer can legally build a charger using this specific shared DC bus topology. Patent applications are pending in both the US and Canada.
SKUs follow the pattern: {Family}{Power}-B{Battery_kWh}{Chemistry}-{Ports}C
For example, LYNX48-B50N-12C reads as: LYNX charger family, 48 A rated, 50 kWh battery using Na-ion chemistry, 12-port cluster. Another example: SPHINX240-B121N-4C = SPHINX 240 kW DCFC, 121.8 kWh Na-ion battery, 4-port cluster.
Battery chemistry suffix: S = SuperCap (3C, ultra-long life), N = Na-ion RockNa (5C, cost-optimized). Both are field-selectable based on site requirements.
Yes. The eMÖTEN Charger Management System is certified compliant with NEC 625.42(A), which allows EVSE load calculations to use the CMS-managed maximum demand instead of the nameplate sum. This is the same code provision that makes shared-circuit and dynamic load management installations legal under the National Electrical Code.
The DRACO ESS module is certified to UL 9540 (3rd Edition) for energy storage system safety, and the bidirectional PCS is certified to UL 1741 for grid-interactive inverters. All charger families carry ETL or UL listings. We provide AHJ-ready documentation packages (CMS load study + UL listing letters + one-line diagrams) for every installation.
Yes. Free shipping is included with every MÖTEN charger, delivered to your jobsite anywhere in the world. This is meaningful savings since competing manufacturers (ChargePoint, Wallbox, Autel, Enel X, Blink) all charge freight separately on top of hardware cost.
This is one of three durable moats we offer with every MÖTEN charger: (1) free shipping to your jobsite, (2) eMÖTEN CMS included on all MÖTEN hardware, and (3) the patented XEYAR architecture. No competitor offers any of the three; we offer all three by default with every MÖTEN charger.
L2 cluster systems typically ship in 5–7 business days from US stock and commission in 1–3 days on-site. DC cluster systems ship in 4–8 weeks depending on configuration (KOMODO 720 kW hubs, with cabinet + dispensers, run on the longer end) and commission in 7–21 days on-site.
The big time win comes from not waiting for utility infrastructure. A conventional non-buffered 12-port L2 site requires a transformer or service upgrade that typically takes 6–9 months through the utility. Our equivalent LYNX48-B50N-12C cluster commissions in days because it runs on existing 100 A service.
