                                                                                                                                                                          盖世汽车讯 据外媒报道,海拉(Hella)是全球领先的汽车照明和电子设备生产商之一,该公司宣布为部分电动的汽车,即轻混汽车推出“双电压电池管理系统”以及48伏PowerPack,新产品主要服务于日益增长的48V轻混汽车市场。据总部位于伦敦的分析公司IHS Markit的研究,全球轻混汽车市场新注册用户将从2020年的600万增长至2030年的3500万。

                                                                                                                                                                          从2020年开始,欧盟规定新注册汽车的CO2排放量每公里不得超过95克,而海拉表示其新解决方案能够使汽车CO2排放量每公里少5至6克,从而可在短期内帮助汽车达到CO2排放目标。

                                                                                                                                                                          海拉已经为紧凑型和中型车研发了双电压电池管理系统,该系统可将内燃机车变成轻混车,结合了48V电池、12V电池和变压器(DC-DC变流器)等单独的核心部件,而且都封装在一个传统的铅酸电池包装内,可轻易将其集成至现有的汽车架构中。此外,该双电压电池管理系统还消除了铅酸电池的需要,该系统由锂离子电池组成,可根据应用情况智能切换,因此可用于12V或48V的汽车电气系统。

                                                                                                                                                                          海拉还为功率更高的车辆设计了48V的powerpack,结合了48V锂离子电池组,该电池组包括电池管理系统和DC-DC变流器。除12V电池之外,48V的powerpack也被安装在车内,可支持恢复(制动时恢复能量的能力)或主动滑行(驾驶时关闭内燃机)等混动功能,以及支持用于豪华车型的其他功能,包括环境照明,自动气候控制以及主动底盘控制等。
