Vekloud Solid lithium battery

Vekloud Solid-State LiFePO₄ High-Power Energy Cabinet (UPS Battery System)

• Chemistry / safety: Solid-state LiFePO₄ designed for extreme safety (no swelling, no smoke, no fire, no explosion under severe conditions).

• Fast recharge: 4C charging — can recover to full capacity in as fast as ~15 minutes after discharge (application dependent).

• High power output: 6C discharge — supports high inrush / impact loads and large transient currents.

• Long lifetime: 15-year design life and ~4000 cycles (capacity retention >80% after 4000 cycles under typical test conditions).

• Wide temperature capability: Charging 0 to +55°C; discharge typically down to -20°C (system dependent).

• Low footprint / weight advantage: For the same usable energy, footprint and floor loading demand can be about one-third of traditional lead-acid solutions.

• Integrated delivery: Battery packs + high-voltage box + cabinet + monitoring are integrated; reduces on-site installation workload by 80%+.

• Smart monitoring & protection: 3-level BMS (cell/module/system) with real-time monitoring, active balancing, multi-layer protections, SOC/SOH tracking, alarms & event logs.

• HV control unit: Up to 1000 V / 500 A, automatic fault isolation; supports solutions with neutral (where required).

• Communications: RS485, TCP/IP, dry contacts for UPS/DCIM/BMS integration.

• Monitoring platforms: Local display + PC + mobile platform; SOC accuracy typically <5%.

• Scalability: Supports paralleling up to 20 cabinets (energy expansion).

• Self-discharge: Typically ≤3% per month (at moderate temperatures).

• Cooling / wiring: Forced-air cooling; supports top or bottom cable entry.

Available configurations (use “Li + actual V/Ah” as the model name)

All options use 108Ah battery packs; voltage increases with series count:

• Li 204.8V 108Ah — 22 kWh, 4 packs (series)

• Li 307.2V 108Ah — 33 kWh, 6 packs (series)

• Li 409.6V 108Ah — 44 kWh, 8 packs (series)

• Li 512.0V 108Ah — 55 kWh, 10 packs (series)

UPS sizing principles (quick rules)

• Ensure the UPS DC voltage window matches the battery system DC window.

• Energy sizing: (UPS rated capacity × backup hours) ≈ (Battery nominal energy × quantity).

• Power sizing guideline: UPS rated power should not exceed ~4× the battery system total power capability (to keep high-rate operation within safe margins).
