The solution is to be used in the NETA vehicle series.
Infineon’s BMS solution was developed together with the supporting supplier B&Z Technology. This solution promotes the development of NEVs towards high-performance and high quality. B&Z handles system design and development, testing and verification, mass production and delivery; whereas Infineon provides the relevant technical support.
This BMS solution has been adopted and implemented by NETA Auto, a Chinese new energy vehicle (NEV) manufacturer. The solution is to be used in the NETA vehicle series.
Zhang Yong, NETA Co-Founder & CEO, “Innovation to drive customer value increasingly depends on our ability to differentiate our customers’ systems. By leveraging Infineon’s BMS total solution, we can provide system functionality to our customers while reducing system cost and system deployment time.”
Freeman Cao, Senior Vice President & Head ATV of Infineon Greater China, “Infineon products have an outstanding position in the areas of vehicle electrification, autonomous driving, connected vehicles and security. We always consider product quality as a fundamental driver and strive to achieve the goal of zero defects while meeting the highest requirements for functionality, reliability and time-to-market against cost. Last year, Infineon shipped several billions of automotive devices, which is the best affirmation of Infineon’s product quality by the market.”
The BMS solution was designed to meet the system requirements for NEVs. It adopts different chips from Infineon: the latest generation of the Li-ion battery monitoring and balancing IC TLE9012DQU, the iso UART transceiver IC TLE9015DQU. In addition, the main controller uses the AURIX MCU.
The TLE9015DQU is internally equipped with a bidirectional daisy-chain signal transceiver function. This sends acquired data in both directions to ensure that each analogue front end (AFE) draws the same amount of power during operation. This provides equal power consumption and reduces the risk of unbalanced cell voltage.
