This industrial-grade Lithium Iron Phosphate (LiFePO4) battery pack supplies primary traction and auxiliary power for commercial electric maintenance vehicles. Designed as a direct drop-in replacement for traditional lead-acid systems, it provides a stable voltage platform, eliminates routine maintenance, and delivers high resistance to shock and mechanical vibration. Built with an integrated Smart Battery Management System (BMS), the unit monitors cell voltages, thermal behavior, and state of charge (SoC) in real time to ensure operational safety across diverse fleet environments.
Compatibility & Applications
Target Vehicle Fleet: Airport baggage tugs, municipal utility trucks, floor sweepers, scissor lifts, and industrial heavy-duty burden carriers.
Mechanical Retrofitting: Custom-engineered enclosure footprints match the exact battery well dimensions of legacy lead-acid setups, minimizing chassis modification for vehicle OEMs.
Charger Compatibility: Operates seamlessly with standard industrial off-board and on-board high-frequency chargers programmed for LFP charging curves (CC/CV).
Key Features
Extended Cycle Lifetime: Delivers >= 3,500 cycles at 80% Depth of Discharge (DoD) under nominal testing conditions (25 deg C), reducing total fleet replacement frequency.
High Discharge Capability: Sustains high continuous and pulse currents to support heavy starting loads, steep inclines, and hydraulic lifting mechanisms without sudden voltage sag.
Smart Thermal Management: Integrated low-temperature firmware logic prevents charging when ambient temperatures drop below 0 deg C to protect cell chemistry, with optional internal heating films for sub-zero climates.
Robust Telematics Integration: Transmits diagnostic data, fault codes, and real-time operational parameters directly to vehicle controllers via CAN 2.0 (J1939 / CANopen protocol optional).
Industrial Vibration Resistance: Internal cell arrays and busbars are secured using reinforced structural framing and shock-absorbing damping pads, engineered to withstand continuous road impact (ISO 16750-3 compliant).

FAQ
Q: Can this battery be installed directly into existing legacy lead-acid battery compartments?
A: Yes. We design custom mechanical enclosures to match your exact spatial dimensions, weight distribution, and terminal locations. Send us your compartment drawing or legacy battery model for a precise drop-in fit.
Q: What is the expected calendar and cycle life under rigorous daily fleet operation?
A: The battery is rated for >= 3,500 cycles at 80% Depth of Discharge (DoD) at 25 deg C before dropping below 80% of original capacity. Calendar life typically exceeds 8 to 10 years depending on operational intensity and depth of discharge.
Q: How does the system handle cold-weather charging and operations?
A: The discharge cycle functions down to -30 deg C. For charging below 0 deg C, the BMS automatically blocks current to protect cell chemistry, or optionally triggers internal low-energy heating pads prior to charge initiation.
Q: What compliance and export testing documents are included?
A: Every shipment includes UN 38.3, CE, and RoHS documentation. Comprehensive test reports covering vibration, mechanical shock, external short-circuit, and thermal stability are available upon request.
Q: What is the typical lead time for custom prototype development?
A: Initial 2D/3D mechanical drawings are delivered within 3 business days. Prototype sample production takes 15 to 20 days, and batch manufacturing runs require 30 to 45 days depending on total volume.
Q: What charging equipment is required for these packs?
A: The pack requires a Constant Current / Constant Voltage (CC/CV) charging profile configured specifically for LFP chemistry, with a maximum per-cell limit strictly regulated by the onboard BMS.
