REDARTI Lithium Battery Chargers are intelligent power systems developed to meet the precise and safe charging requirements of battery banks with advanced lithium chemistries such as Lithium-Ion (Li-Ion), Lithium Iron Phosphate (LiFePO4) and Lithium Titanate (LTO). Designed around the sensitivity of lithium cells to voltage and temperature instability, REDARTI's proprietary microprocessor software prevents cell overcharging, overheating and capacity loss 100%, maximising battery service life.
Depending on the efficiency, volume and power level the application requires, our systems are built in both high-frequency IGBT Switch-Mode (SMPS) and heavy-duty thyristor-controlled (SCR) topologies. Sharing the same industrial robustness, corrosion protection and high insulation standards as our marine chargers, the RED-LION series serves fully automatically and reliably across a wide range of applications — from electric vehicles and marine use to AGV/AMR robots, telecommunications and renewable energy storage facilities.
Smart Charging Algorithm and Safety Measures for Lithium Batteries
Compared with lead-acid batteries, lithium chemistry requires millivolt-level voltage tracking and tight current limiting. REDARTI's proprietary charging software offers the following technical advantages:
- CC/CV (Constant Current / Constant Voltage) Profile That Protects the Cell Chemistry: Charging starts with fast filling at a preset safe current level (Constant Current – CC). When the cell voltage reaches the critical limit, the charger automatically switches to Constant Voltage (CV) mode and reduces the current step by step. Once charging is complete it either cuts the current entirely or switches to float mode, preventing the battery from overheating.
- Fully Automatic Operation with BMS-Compatible Regulation: Thanks to a regulation structure that works in full synchronisation with the battery management system (BMS), the charger instantly reduces current during cell voltage imbalances and lets the BMS complete its cell balancing process without interruption.
- Reverse Polarity, Short-Circuit and Over-Voltage Protection: Hardware and software reverse-polarity protection, together with sudden short-circuit and over-current interlocks, provides full protection against human error when connecting the battery.
Display, Control and Communication
- Flexible Display Options: Depending on user preference and budget, a 4x20-character industrial LCD panel or a standard 3-parameter digital display showing current (A), voltage (V) and charge time in real time is available.
- Optional Modbus RTU (RS485) Communication: A Modbus communication interface fully compatible with industrial automation systems, marine SCADA panels or energy monitoring centres can be integrated as an option. The battery state of charge (SOC), live charging voltage/current and any fault codes can then be monitored and controlled remotely.
- Industrial Enclosure with Marine-Grade Durability: Specially protected chassis with electrostatic oven-baked powder coating, resistant to humid, corrosive sites with high corrosion risk.
Topology Options: Switch-Mode and Thyristor-Controlled
- IGBT Switch-Mode Lithium Chargers: High-frequency (30–35 kHz) switching technology for high efficiency (>95%), low ripple (<1%) and an ultra-light, compact design. Ideal especially for marine, electric vehicle, AGV robot and space-constrained installations.
- Thyristor-Controlled Lithium Chargers: Extremely rugged construction with an isolation transformer, built for heavy industrial conditions. Offers maximum durability at high kW/kVA ratings and under harsh grid conditions.
Applications
- Marine and Yachting: Electric boats, luxury yachts, hybrid marine craft and service battery banks.
- Industrial Warehouses and Logistics Facilities: Lithium-powered AGV / AMR autonomous robots, forklifts and stackers.
- Renewable Energy and Storage Systems: Lithium battery banks in solar (PV) and wind energy storage facilities.
- Telecommunications and Data Centres: Base stations and lithium backup systems requiring uninterruptible power.
