Low Efficiency & Long Downtime: Requires 8-12 hours to fully charge plus cooling time. Multi-shift operations demand 2-3 battery sets per truck, causing frequent battery swapping and lost productivity.
High Total Cost of Ownership (TCO): Short lifespan (1.5-2 years), high replacement frequency, and continuous maintenance costs (acid topping, watering, and ventilation infrastructure).
Bulky & Space-Consuming: Low energy density results in oversized battery boxes and restricts modern compact forklift designs. Dedicated charging rooms take up valuable warehouse space.
Lack of Smart Integration: No standard CAN communication interface, creating an operational "black box" that prevents fleet managers from tracking battery health (SOH/SOC) or conducting predictive maintenance.
For the vast existing forklift market, Qianhang provides more than just a battery replacement—we deliver a comprehensive power system upgrade solution. Driven by precision, safety, and compatibility, our hardware retrofit solution ensures maximum return on investment for our clients at the lowest possible cost.
