Jing-Jin Electric Enhances NEV Drive System Production in Anticipation of Market Growth in China

Jing-Jin Electric Technologies (Beijing) Co., Ltd. (JJE) is a Chinese drive motor supplier for new-energy vehicles (NEV). It has an R&D center in Beijing and production plants in Shanghai, Hebei, Zhejiang and Shandong. Drive motor delivery to automakers dropped 21.1% year-on-year in 2019 to 94,000 units due to the government’s decision to reduce subsidies on NEV purchases. In the first quarter of 2020, delivery declined 91.6% to 2,800 units as a result of the outbreak of the new coronavirus among other factors.

Despite reduced subsidies and the impact of the new coronavirus, JJE is working on expanding production capacity in anticipation of sustainable growth in the NEV market. The company is building an e-axle plant Heze, Shandong province to supply BEV and PHEV models. The plant is scheduled to be fully operational in 2022.

JJE is working on improving performance by integrating drive systems for NEV models. In addition, 2-in-1 e-axles which combine a motor and a gearbox, JJE has launched the 3-in-1 JJE-EDM3000F series e-axle which integrates a motor, a gearbox and an inverter. The motor’s rotational speed was increased from 12,000rpm to 16,000rpm, the gearbox’s cost was reduced 15–20% and total weight was lowered 2–3kg.

JJE has been mainly supplying GAC Group and Geely Automobile. The supplier expanded its clientele in 2020 by starting supplying Foton’s M4 light truck, Xpeng’s P7 and SAIC Maxus’ EUNIQ6.
