Description
技术领域
本发明涉及新能源汽车技术领域,更为具体地说是指一种储能系统、方法及新能源汽车。
背景技术
载重大、功率大、能耗高、工况恶劣和长运距是商用车应用的特点,对于新能源商用车需要配置大电量电池才能满足使用功率和续航要求。采用传统的枪充方式,充电时间长,直接影响运营效率,故充换一体换电箱应运而生。目前,现有的商用车通常将换电箱安装在车头的后方,不仅占用载货空间,空间利用率低,而且换电箱较高,在急刹车工况下有前倾被压驾驶室的风险。
公开号为CN112477573A的中国发明专利公开了一种吊装换电式运载车辆,该专利采用的是现有技术中的吊装换电方式,占用车辆载货空间,虽然设置了防倾斜装置,无法完全避免电池箱背压驾驶室的风险,且该专利方案采用的是整体换电方式,用户无法自由配置,灵活性差,同时不适用于多平台车型。而公开号为CN112319302A的中国发明专利公开了一种电动商用车换电系统,该专利通过车辆大梁底部设置横置电池仓,其一端设仓门,另一端壁设同电池包插头对接的连接插座,电池仓内部设舱内轨道同电池包滚轮配合,实现侧抽换电,完全避免了电池箱背压驾驶室的风险。然而,该专利未公开电池包的工作方式,且无法适用多平台车型。
为此,我们提供一种储能系统、方法及新能源汽车。
发明内容
本发明提供一种储能系统、方法及新能源汽车,以克服现有商用车的换电箱占用载货空间,空间利用率低,且换电箱较高,急刹车工况下有前倾背压驾驶室的风险等缺点。
本发明采用如下技术方案:
一种储能系统,应用于商用车,包括一底盘主体,所述底盘主体包括前桥区和底盘中段,所述底盘中段从右至左依次分为中段右区、中段中区以及中段左区,所述前桥区底部布置有F模块,所述中段右区、中段中区以及中段左区底部分别对应布置有R模块、M模块以及L模块;对于纯电动车型,所述F模块为不可换电固定电池包,所述R模块及所述L模块均为充换一体电池包,所述M模块为充换一体电池包或不可换电固定电池包;对于混动车型,所述F模块为增程器,所述M模块为不可换电固定电池包,所述R模块和所述L模块均为储气瓶,或者均为储油罐。
上述储能系统应用于纯电动商用车时:
一种实施方案中,所述F模块及所述M模块均为不可换电固定电池包,组成车辆的固定能量源;所述R模块和所述L模块均为充换一体电池包,组成车辆的补充能量源。
另一种实施方案中,所述F模块为不可换电固定电池包,作为商用车吊钩机构、空调或救援车救援设备等的固定能量源;所述R模块、M模块及L模块均为充换一体电池包,组成车辆的能量源。
上述储能系统应用于混动商用车时,所述F模块与所述M模块组成车辆的固定储能单元,所述R模块和所述L模块组成车辆的主能量源。
本发明还提供一种纯电动商用车的能量选择方法,包括上述一种储能系统,当M模块为不可换电固定电池包时,具体步骤如下:
A1、系统启动进入判定,识别系统充换一体能量源个数;
A2、对步骤A1中充换一体能量源进行SOC排序,确认固定能量源无故障,锁定固定能量源为主能量源,车辆进入持续作业状态;
A3、作业过程中,持续判断本次启动主能量源的SOC和故障状态,如SOC较低或有故障且还有作业需求,则将主能量源自动切换至充换一体能量源中无故障的SOC最高者,返回继续作业;
A4、如无作业需求,则结束流程。
本发明一种纯电动商用车的能量选择方法,当模块为充换一体电池包时,其具体步骤则如下:
B1、系统启动进入判定,识别系统充换一体能量源个数;
B2、对步骤B1中各能量源进行SOC排序,优选出SOC最高者,确认无故障,锁定为主能量源,车辆进入持续作业状态;
B3、作业过程中,持续判断本次启动主能量源的SOC和故障状态,如SOC较低或有故障且还有作业需求,则将主能量源自动切换至剩下的能量源中无故障的SOC最高者,返回继续作业;
B4、如无作业需求,则结束流程。
由上述对本发明的描述可知,和现有技术相比,本发明具有如下优点:
1、本发明将电池包固定在底盘主体的底部,提高空间利用率,增加载货空间,无电池包背压驾驶室风险。
2、本发明在同一架构上通过底盘主体划分并设置换电区域,实现多种形态电池灵活组合,可充可换,用户可根据实际运营场景需求灵活自由扩减容,提高了车辆使用的灵活性和适用性,同时底部换电更安全。
3、本发明的储能系统具备可拓展性,在同一架构上将车辆底盘中段左右两侧的L模块及R模块替换为储气瓶或储油罐,并在驾驶室下方的前桥段增加不同燃料类型增程器,实现在现有驱动和电池架构不变的情况下,直接用于混动车型,降低车辆开发成本。
4、本发明采用分布式局部换电方式,各电池包均可独立使用,更加灵活便利。
5、本发明通过一种能量源选择方法,实现车载能源的自动切换,进而实现增程或提高作业强度。
