NXPNEWTEC－NTBMS汽车电池管理参考设计

NXP公司的NEWTEC－NTBMS是汽车功能安全完整性等级高达ASIL C的汽车电池管理参考设计,和ISO 26262标准ASIL C兼容,包括两块板:功能安全系统模块(Safety SoM)和电池管理系统(BMS)应用板.Safety SoM基于NXP公司的S32K144和KEA微控制器和FS4503C安全电源系统.BMS应用板基于NXP公司的电池控制器,能够永久测量电池电压,超温保护,过流/过压检测,欠压检测(短路),安全继电器控制(ASIL C),非故意的继电器闭合和断开,各种定义的安全状态以及LIN和CAN总线接口,可控制多达6个锂电池,连续载流能力200A,最大电流800A,主要用在汽车BMS,智能电网和其它电池管理系统(医疗,电动自行车,轻型交通和工业).本文介绍了NewTec NTBMS主要特性,框图,技术数据以及安全特性高达ASIL C电池管理参考设计NEWTEC-NTBMS主要特性,框图,建力图和电路图.

NewTec NTBMS is an e-mobility reference design and complete safety support package for Battery Management Systems. It is constructed with a two boards approach a functional safety System-on-Module (Safety SoM) board and a Battery Management System (BMS) application board. The Safety SoM is based on NXP＇s S32K144 and KEA microcontrollers, and FS4503C safety power system. The BMS application board is based on NXP＇s MC33772B battery cell controller IC. The support package includes the necessary safety documentation and software for certification purposes. It is intended for device manufacturers with Lithium-ion batteries and suppliers of automotive or industrial applications with a high degree of reliability and safety in accordance with ISO 26262 targeting safety level up to ASIL C, or IEC61508 SIL2.

Typical use cases would be:

Automotive Battery Management System for 14V auxiliary battery

Monitoring of starter batteries

Extendable to 48V battery systems

Stationary Energy Storage systems; Smart Grid
