研发完成动力电池化成分容用高精度双向 ACDC 电源，效率业界最高超越竞争对手 17%以上， 精度达到 0.05% 兼任电池化成双向 ACDC 电源及充电桩的产品经理负责项目推进及市场推广,并陪同公司销 售拜访国内运营商、生产企业等客户并提供技术支持并解决相关技术问题。 精通 Photoshop、Coredraw、MS PPT、MS Word、MS Excel，MS Project 等工具，阅读了《Yes！ 产品经理（工具篇）》、《产品经理手册》、《高效能人士的七个习惯》等书籍。As the advanced project manager, lead the team to research and design bidirectional ACDC power module. The device is used in formation & grading system of Lithium battery. In short, The device will work in converter and inverter mode. it can charge the battery and discharge battery to feed back energy to the Grid. The project was finished, the battery side’s voltage(0~5Vdc) and current(0~60A)’s accuracy is less than 0.1%, the efficiency(charging mode and discharging mode) are more than 80%. And in various cases, it is more than 17%~33% points beyond the opponents. Because the company's marketing team isn’t good at promoting new products, boss ask me to serve as a product manager, in charge of R&D progress, Customer exchange, Market research and analysis, Product promotion etc. I have studied MS PPT, MS Word, MS Excel, Photoshop, Coredraw in my spare time. I have learned the product manager knowledge and product process management. I have often accompanied sales to visit domestic operators, manufacturers and other customers and provided technical support to solve technical problems or answered the question of customers.
