Financial news on April 9, 2025, revealed that Zhuhai Rongbo Drive Technology Co., Ltd. applied for a patent titled "Hybrid Transmission Energy - Saving Oil Pump System and Control Method" (public number CN 119778464 A) in March 2025. The oil pump system includes multiple pumps and valves. By making different pumps start, stop, and reverse according to various working conditions, it can reduce the energy consumption of the mechanical pumps. Specifically, a high - pressure, small - flow pump provides pressure and flow for clutch pressure building and maintenance, while a low - pressure, large - flow pump supplies cooling and lubrication flow. This system improves the efficiency of the hybrid transmission and reduces vehicle fuel consumption.
