Leading Energy DensityThe 33kWh lithium-ion energy storage system utilizes lithium iron phosphate (LFP) batteries, which offer high energy density—more than three times that of traditional lead-acid batteries. Within the limited space available in a vehicle, this enables a lighter design while meeting the power requirements of CT equipment, which consumes approximately 5–10 kWh per scan. It supports the completion of 3–6 full scans consecutively, covering the power needs of most emergency scenarios.

Long Cycle Life and Cost-Effectiveness LFP batteries have a cycle life exceeding 6,000 cycles and can maintain a service life of over 10 years at an 80% depth of discharge (DOD), significantly reducing total cost of ownership. For example, in a mobile CT project utilizing a 33kWh lithium-ion system, with an average of 20 scans per day, the battery life can still cover the equipment’s 10-year service life, avoiding the high costs associated with frequent battery replacements.

AC/DC Automatic Switching Power Supply Technology The system integrates AC/DC detection and automatic switching circuits, making it compatible with 220V/380V AC and DC inputs. When the vehicle is connected to the mains or an external power source, it prioritizes the external power supply and charges the battery; in the absence of external power, it automatically switches to battery power to ensure uninterrupted operation of the CT equipment. For example, when a mobile CT unit performs lung cancer screening in remote mountainous areas, its 33kWh lithium-ion battery system supports continuous operation for 8 hours, covering the screening needs of three villages.

Multi-Level Protection and Thermal Management The Battery Management System (BMS) continuously monitors voltage, temperature, and SOC (State of Charge) to prevent overcharging, over-discharging, and short-circuit risks. The system is equipped with a liquid-cooled heat dissipation module that maintains a battery capacity degradation rate below 20% even in high-temperature environments (e.g., 55°C), ensuring stability under extreme conditions. Additionally, the BMS supports a soft-start function to buffer the inrush current during CT device startup, thereby extending battery life.
