Littelfuse高压配电盒解决方案,支持定制开发,满足不同客户不同车型需求
BDU(Battery Disconnect Unit),电池断路单元,又叫电池分配单元,作为高压配电盒的一种,设计于电池包内部, 起到保护新能源汽车电池模块与电路分配的作用,是电动汽车高压电路重要构成部分,可分为电池箱内与箱外两种安装方式。箱内安装式的外壳一般为塑料材质,没有IP等级要求;箱外安装式一般为铝合金壳体,满足IP67等级要求。
其作用是协调驱动电机控制系统,电池管理系统, 充电管理系统,DC/DC,电空调,电助力转向,制动系统等高压附件的功能转换和能量分配;此外,还可以实现短路过载的快速断电保护,防漏电保护等安全保护功能。 使汽车维护更简单,安装更方便,美化车内设计与减小占用空间, 使汽车电池寿命更长久, 减少汽车日常维护成本。

一般构成
●主正、主负继电器,导通/切断电池包主路直流电流。
●预充继电器、预充电阻,主电路中有大电容用于维持工作时的电压平衡,上电之前其电位为0,因此需要预充回路限制上电瞬间大电流,起到保护高压线路的作用。
●电流传感器,用来测量和计算电池包容量,同时具有过流监测与提供信号的功能
●铜排、连接器、线束,用来作为主功率回路导通的路径与接口。
在电池包的总正和总负端均配置主接触器向系统高压部件提供高压直流供给。另外,主接触器可以在充电或者电流回馈时向电池包输入电流。当系统报错时,电池系统基于整车控制器命令通过主接触器切断电流以保证系统安全。
除了熔断器作为被动保护,电池包里面也有引入智能熔断器Pyrofuse,又叫爆炸保险丝、烟火控制开关,通过检测外部碰撞传感器来控制保险丝熔断,起到主动切断电路的作用。
PDU定义
PDU (Power Distribution Unit),高压配电单元,功能是负责新能源车高压系统中的电源分配与管理,为整车提供充放电控制、高压部件上电控制、电路过载短路保护、高压采样、低压控制等功能,保护和监控高压系统的运行。
一般构成
PDU能够集成BMS主控、交流慢充、直流快充、直流变换、PTC控制、助力转向、空压机等的过流与控制功能,与传统PDU相比多了整车功能模块,功能上更加集成化,结构上更复杂,具有水冷或是风冷等散热结构。PDU配置灵活,可以根据客户要求进行定制开发,能够满足不同客户不同车型需求,比如三合一,四合一,五合一等。
