中国电池管理系统亮相法兰克福国际车展

2017-09-15 07:26:41   央广网

然而,目前国内的汽车电池能量管理系统技术水平参差不齐,已经成为电动汽车市场进一步发展的瓶颈。近年来,随着新能源汽车在国内的大量推广使用,关于新能源汽车的自燃、虚假续航里程等问题时有发生,也反映出国内在电池组、电池管理系统等方面的设计、检测、生产标准还不够完善。

面对电动汽车用户对于能效、寿命、安全、节能等更高的诉求,市场亟需高水平的电动车能量管理系统。

据什维科技有关人士介绍,该公司新推出的这套GAZELE3电动车能量管理系统,可谓电动车电池的“好管家”。该系统可支持高达400伏2000安培的峰值输出功率。在测试中,可使5人座后驱车0-100公里/小时的加速时间在2.8秒以内,最高时速达到250公里。8人座(前驱+后驱)0-100公里/小时的加速时间最低可在4秒以内,最高时速可达230公里/小时。

有业内人士认为,这一产品如运用到国内新能源汽车上,不仅能够保障车辆安全可靠运行,还可有效提升电动汽车技术性能。

什维科技新推出GAZELE3电动车能量管理系统

  领先一步的技术优势

据什维科技有关人士介绍,相比国内现有的BMS系统,GAZELE3能量管理系统具有多种技术优势。

首先,GAZELE3系统可以延长电动汽车单次充电后的里程数。

该系统对能量系统内部的关键技术指标的检测精度更高,可以对电池包的电压、电流、温度,甚至湿度等工况进行实时分布式网络化多点采样,精确监测,并实时进行高精度调控以确保正常安全运行。通过监测所得的大量数据,以及基于神经元网络的人工智能算法,GAZELE3系统对电池包充电状态(即SOC)的估算精度可达到正负1%以内,远高于目前行业正负3%的标准。

其次,GAZELE3系统能有效延长电池包的使用寿命,降低用户使用成本。

由于采用了电池间主动平衡技术,GAZELE3系统能根据电池电压的变化及各电池电压参差不齐的情况,对最低电压的电池进行主动平衡充电,发挥每节电池的最大效能,因此能量使用效率更高,整个电池包的使用寿命也得到了延长,用户的使用成本得到了降低。同时,这套系统采用了高冗余的设计,在子系统出现故障时,依然能够保持整个系统维持在一定的工作状态,保证车主行驶到修理厂,避免了半路抛锚。
