Puhang Special Electric – Pioneering waterway management and empowering smart maritime operations.
The system adopts a technical approach that integrates “high-precision power supply + multi‑type load simulation + multi‑channel data acquisition + automated analysis,” incorporating a programmable DC power supply, a multi‑mode electronic load, a realistic diode‑simulating load, a high‑bandwidth data acquisition system, intelligent analysis software, and an efficient thermal management system. Its core objective is to conduct comprehensive, efficient, and precise testing and evaluation of the device under test’s functional specifications, output performance, and operational stability, meeting the requirements of R&D validation, production‑line screening, and reliability testing.
The QGD-10-Z20 energy-storage‑type starting power unit is primarily used to supply electrical power for the starting of engines and for field maintenance of helicopters in the Z‑8, Z‑10, Z‑20, Z‑20T, Mi‑171, and other series. Its power output complies with the relevant requirements specified in GJB 3706‑1999, “Power Supply Characteristics and General Requirements for Military Helicopter Ground Power Units.”
A certain logistics support unit, based on its experience with routine helicopter maintenance and engine start‑up operations, has developed a specialized energy‑storage‑based power supply unit designed to provide reliable start‑up and maintenance support for various helicopter models in harsh, low‑temperature conditions and without access to grid electricity.
The L2335A lithium battery pack consists primarily of an instrument battery pack, a power battery pack, a battery management system, connectors, and wiring harnesses. The battery management system provides protection against overvoltage, undervoltage, overcurrent, overheating, and short circuits; it also features CAN communication to report the battery pack’s operating status. Power-up is controlled by a remote self‑locking switch, which is routed out via a connector.
A 300 V/24 V (145 kWh) lithium‑ion battery pack serves as the power source for the unmanned underwater vehicle, featuring charge–discharge capabilities and reusable rechargeability, thereby meeting the vehicle’s requirements for surface‑ and underwater‑energy replenishment. Relevant battery‑pack data can be exchanged via CAN communication.
