7月24日,上海汽检安亭试车场地表温度高达60℃。酷暑下,上汽MG新款车型搭载上汽新一代主动散热电驱,完成全球首次电动车连续100次零百加速挑战。100轮连续测试中,车辆零百加速最快达到5.67秒,全程未出现明显动力衰减。 对于电动汽车而言,相比单次零百加速,连续100次测试更考验车辆在持续高负荷工况下的动力稳定性。电机持续高功率运转会不断产生热量,一旦散热能力跟不上,为保护电机、电控等核心部件,系统便可能限制功率,车辆的加速性能也会随之下降。…

7月24日,上海汽检安亭试车场地表温度高达60℃。酷暑下,上汽MG新款车型搭载上汽新一代主动散热电驱,完成全球首次电动车连续100次零百加速挑战。100轮连续测试中,车辆零百加速最快达到5.67秒,全程未出现明显动力衰减。 对于电动汽车而言,相比单次零百加速,连续100次测试更考验车辆在持续高负荷工况下的动力稳定性。电机持续高功率运转会不断产生热量,一旦散热能力跟不上,为保护电机、电控等核心部件,系统便可能限制功率,车辆的加速性能也会随之下降。 “这次测试的重点不是车辆单次零百加速能跑多快,而要经过百轮连续加速再急减速后,看车辆动力和制动是否依然稳定。”上汽MG公关负责人葛思亮介绍,选择在大暑时节开展测试,就是希望将车置于高温、高负荷的严苛工况下,检验并呈现其真实的性能表现。 葛思亮介绍,上汽全新一代超高集成度主动散热电驱在集成电机、电机控制器、减速器等单元的基础上,进一步将热管理部件及软件控制系统纳入一体化设计,缩小系统体积30%,同时提升电机散热能力。此外,上汽首创双比例八通阀一体式热管理系统可在日常行驶中实现电机、电控、电池三条回路独立运行,使各部件保持在适宜的工作温度,解决持续高负荷运行中容易积热、动力衰减的行业难题。材料结构上,电驱应用首创一体式大压铸电机壳体,不仅能够承受更大的扭矩,还能从源头抑制振动和异响,改善车辆行驶时的静谧性。 上汽集团自2009年启动新能源三电核心技术自主研发,并持续推进纯电、插电混动、电池、电驱及软件控制等领域的技术储备。从2012年首款纯电车型量产、2013年首款插电混动车型量产,到近年来半固态电池和主动散热电机等技术落地,上汽不断将基础研发转化为量产产品。…
