Parking lots are natural homes for EV charging—but many only have single-phase power, making standard 3-phase fast-charge builds slow and expensive. B.E.S.T (Buima Energy Storage Tile) changes the equation by delivering 400 VDC fast charging from single-phase 220 VAC, with thin, modular tiles that respect space, budget, and design.

Why parking lots love B.E.S.T

1) Fast DC without 3-phase

Get 400 VDC fast charging from single-phase 220 VAC, avoiding utility service upgrades, new transformers, and heavy civil works. Many sites see up to 50% lower site CAPEX versus building a conventional 3-phase DC station.Note: Savings depend on utility rules, distance to service, and site conditions.

2) Space-smart, site-friendly design

B.E.S.T tiles are 90×90×6.7 cm and mount flush on walls, fences, or compact plinths—preserving stalls and sightlines. Custom-print facades let owners brand the system or match architectural finishes so equipment enhances the property instead of cluttering it.

3) Built to scale and balance

Demand varies by hour and season. With series/parallel configurations, B.E.S.T can increase capacity (parallel) and step up voltage (series) to support more bays or higher charger power—while helping balance loads across lanes.

4) Solar-ready economics

Pair canopy or rooftop PV with B.E.S.T to store daytime generation and serve evening/peak charging, cutting demand charges and improving the site’s energy mix. Add revenue streams: charging fees, peak-shaving savings, and sponsorship on branded facades.


Outage-Proof Operations (No More “Free Parking” Mode)

When the grid goes down, many lots must lift gates and offer free parking. With B.E.S.T, priority loads—gate arms, ticketing/POS, LPR cameras, payment kiosks, lighting, CCTV, and DC chargers—stay powered on a protected DC bus. Your site remains operational, access stays controlled, and revenue doesn’t stop.


What operators gain

  • Faster time-to-revenue vs. waiting on 3-phase utility upgrades

  • Clean, predictable bills via EMS-driven peak-shaving and tariff-aware dispatch

  • Resilience: power critical systems (gates, lights, cameras, payment) during outages

  • Better customer experience: clear signage, branded facades, and consistent charger availability


Deployment quick-check (parking lot edition)

  1. Power survey: confirm single-phase 220 VAC capacity and meter location

  2. Siting: walls/fences for tiles (weights); short, protected cable runs to charging bays

  3. PV (optional): canopy or rooftop interconnection plan

  4. Connectivity: network for payments, EMS, and monitoring

  5. Permitting & safety: signage, traffic flow, ADA/accessible paths, bollards


Example layouts

  • Convenience store (2 bays): single-phase service + B.E.S.T buffer → DC fast charging; CAPEX cut vs. 3-phase build; brand the facades.

  • Office lot (4 bays): PV canopy + B.E.S.T → weekday peak-shaving, public charging evenings; higher utilization and cleaner kWh.

  • Fleet corner: load-balanced bays for e-scooters/carts; series/parallel scaling as fleet grows.


Why B.E.S.T is built for the long run

Designed and manufactured in-house in Taiwan, from battery packing to EMS software, for full traceability and quality control. Japanese LFP cells (8000+ cycles @ 1C) and AIoT EMS provide live status, alerts, and transparent reports—SOC, cycles, demand-charge impact—so owners, tenants, and financiers can trust the numbers.

Want a parking-lot plan in days, not months?Send a site photo, meter specs, and the number of bays. We’ll draft a B.E.S.T layout with sizing, charger power options, and a tailored CAPEX/OPEX outlook.
