Strategies for implementing fast-charging cycles during shift breaks to maximize forklift uptime without compromising battery longevity.
Our chargers utilize a sophisticated software-driven charging logic designed to maximize battery life and minimize charging time. This profile is optimized for both Lead-Acid and Lithium-ion (LFP/NMC) chemistry.
Maximum rated current is delivered to the battery until the voltage reaches the absorption threshold (approx. 80% SOC). This stage ensures rapid energy recovery for multi-shift operations.
The voltage is held constant while the current gradually tapers down as the battery reaches full saturation (100% SOC). This prevents overheating and gassing in Lead-Acid units.
A low-level constant voltage is maintained to compensate for self-discharge, keeping the battery at 100% SOC indefinitely without stress or water loss.
For Lead-Acid batteries, the charging voltage is automatically adjusted based on ambient temperature (-3 to -4 mV/°C/cell) to prevent undercharging in winter and overcharging in summer.

An automotive-grade differential signaling protocol. In industrial charging, it enables high-speed, noise-immune data exchange between the charger and the BMS.
Industrial ratings for environmental sealing. IP65 protects against dust and water jets; IP67 is for fully potted units. Mandatory for cold storage and outdoor logistics.
A sophisticated algorithm: Constant Current (CC) for replenishment, Constant Voltage (CV) for saturation, and Maintenance to equalise cells.
A strategy for multi-shift operations. By utilizing short breaks (15-30 mins), batteries are "topped up" at high currents, eliminating battery swapping.

Q: How do I calculate the required charger current for my forklift?
A: For standard 8-10 hour charging, output should be approx. 15-20% of Ah capacity. For fast-charging (2-4 hours), select 40-50% of Ah capacity.
Q: When is 3-Phase input necessary?
A: For power outputs exceeding 5.2kW (e.g., 48V/100A or 80V/65A), 3-Phase input (380V-480V) is standard to ensure efficiency.
