Product Description
The 72V 300Ah LiFePO4 Battery (nominal voltage 76.8V) is engineered to revolutionize urban cleaning operations. Designed for modern electric street sweepers, this high-voltage lithium solution delivers unmatched power density, rapid charging, and near-silent operation—replacing outdated lead-acid systems with a sustainable, cost-effective alternative. Certified for global safety standards (UN38.3, CE, UL1973), it empowers municipalities and contractors to achieve 24/7 cleaning efficiency while slashing operational costs by up to 40%210.
700A Continuous Discharge: Handles peak loads during simultaneous sweeping, suction, and compaction without voltage drop, ensuring consistent performance in hilly or high-debris areas16.
300Ah Capacity: Supports 8–10 hours of continuous operation on a single charge, covering 220+ km per shift—ideal for overnight city cleaning without midday recharging37.
-20°C to 60°C Operation: Arctic-grade cold-start tech maintains >82% capacity at -20°C; liquid cooling prevents overheating in desert climates210.
1.5-Hour Full Charge (vs. 8+ hours for lead-acid): Opportunity charging during breaks extends uptime. Integrated 4C charging accepts 500A current without degradation28.
Smart Energy Recovery: Regenerative braking reclaims 15% kinetic energy during deceleration, boosting efficiency2.
<65 dB Noise Output: Library-quiet operation for early-morning or residential zone cleaning—no public disturbance37.
Zero Tailpipe Emissions: Eliminates CO₂, NOx, and particulate matter, supporting city carbon-neutrality goals (reduces 12 tons CO₂/year per vehicle)710.
Triple-Layer Protection:
Intelligent BMS: Real-time monitoring for overcharge/discharge, short-circuit, and thermal runaway (UL/IEC62619 certified)18.
Flame-Retardant Enclosure: IP67-rated housing resists dust, water jets, and road salt corrosion210.
CellArmor™ Tech: Isolates faulty cells in 0.2 seconds, preventing cascading failures4.
4,000+ Cycles @ 80% DoD: Outlasts lead-acid by 3x, ensuring 8+ years of service with minimal capacity fade210.
