目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
本发明人注意到，在零下三十度的环境中，锂电池为代表的电池组的充放电性能基本为零，因此研究电池组对于提升电动设备对环境的适应度非常重要。基于当前低温环境对电池组性能有很大影响的现象，如何为电池组进行快速加热就成为本申请关注的重点。
为了提高电池加热效率，改善现有加热方法的不利影响，提升电动设备对低温环境的适应度，申请人研究发现，可以在现有的电机控制装置中增加一个加热功率模块，在低温严寒下将加热功率模块与电动回路连接，快速加热动力电池。具体为增加电池自加热振荡电路中储存和释放能量。例如，在只有电机绕组和电机逆变器的电池自加热电路中，若电机绕组的电感量太小，导致自加热时电流无法进一步提高而影响加热效果。另外，若电机绕组电感量太小，很快储存满能量而需要释放，导致逆变器中半导体开关需要更加频繁开启和关断，半导体开关需要承受关断尖峰电压的叠加冲击、以及更高的开关损耗，容易影响逆变器寿命。
基于以上考虑，为了解决电机绕组的电感量太小导致的加热效率低的问题及影响逆变器寿命的问题，发明人经过深入研究，设计了一种电机控制装置，通过在电机控制装置内布置加热功率模块，目的在于进行电流或加热回路的导通控制，让电感与电池正极导通，电感储存的能量流向正极；让电感与电池负极导通，电感储存的能量流向负极。这样的设计，可以使电机绕组中都能通入同向电流，极大减少电机噪音的同时减小了对逆变器寿命的影响。
本申请实施例公开的电机控制装置、驱动装置可以但不限用于车辆、船舶或飞行器等电动设备中。可以使用具备本申请公开的电机控制装置、驱动装置组成的电池加热系统，这样，有利于提升电池自加热效率以及满足用户需求。
本申请实施例提供一种电池加热系统的电动设备，电动设备可以为但不限于电动玩具、电动工具、电瓶车、电动汽车、轮船、航天器等等。其中，电动玩具可以包括固定式或移动式的电动玩具，例如，游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等，航天器可以包括飞机、火箭、航天飞机和宇宙飞船等等。
为了避免在对动力电池加热时增加不必要的成本，可以利用电机回路对动力电池进行加热。
图1示出了传统动力电池加热系统的一种充放电电路图。如图1所示，动力电池加热系统100可以包括电池110，与电池110连接的电机逆变器120以及与电机 逆变器120连接的电机绕组130。动力电池加热系统100还包括控制电机逆变器120的电机控制器140。
对于电池110，不仅可以采用动力电池本身实现，也可以采用外部电池例如充电桩实现。外部电池提供的加热能量例如可以是外接直流充电器输出的，或者是外接交流充电器经过整流后输出的，此处不作具体限制。
对于电机逆变器120，可以采用各种类型的开关实现。例如，电机逆变器120可以由电机驱动系统中的逆变器实现，其中逆变器可以采用绝缘栅双极型功率管(Insulated Gate Bipolar Transistor，IGBT)的桥臂开关实现。具体地，逆变器的桥臂数量与电机绕组130中的绕组数量相同。例如，电机绕组130包括三相绕组电机，逆变器包括三相桥臂，即包括U相桥臂、V相桥臂和W相桥臂。其中，三相桥臂中每相桥臂均具有上桥臂和下桥臂，其上桥臂和下桥臂各自设置有开关单元，即电机逆变器120分别包括U相桥臂中的上桥臂开关121和下桥臂开关122，V相桥臂中的上桥臂开关123和下桥臂开关124，以及W相桥臂中的上桥臂开关125和下桥臂开关126。
对于电机绕组130，可以具体包括：与U相桥臂相连的绕组131，与V相桥臂相连的绕组132以及与W相桥臂相连的绕组133。
需要说明的是，电机绕组130不限于是三相绕组电机，还可以是六相绕组电机、十二相绕组电机等。对应地，电机逆变器120可以包括三相桥臂、六相桥臂或十二相桥臂等。
在一些实施例中，可以通过控制电机逆变器120中的开关周期性通断来调制电流。例如，通过控制电机逆变器120中的目标上桥臂开关和目标下桥臂开关周期性通断来调制电流。在一个示例中，若目标上桥臂开关为上桥臂开关121，则目标下桥臂开关为下桥臂开关124和/或下桥臂开关126。
需要说明的是，周期性地导通和断开每一周期中的目标上桥臂开关和目标下桥臂开关可以相同，也可以不同，在此并不限定。比如，每个周期中均控制上桥臂开关121和下桥臂开关124的导通和断开。又比如，在第一个周期中，控制上桥臂开关121和下桥臂开关124的导通和断开；在第二个周期中，控制上桥臂开关123和下桥臂开关122的导通和断开；在第三个周期中，控制上桥臂开关121、下桥臂开关124和下桥臂开关126的导通和断开，即在不同的周期中，控制的目标上桥臂开关和下桥臂开关可以不同。
由此可见，采用图1所示的充放电电路，目标导通开关包括至少一个上桥臂开关和至少一个下桥臂开关，至少一个上桥臂开关和至少一个下桥臂开关位于不同的桥臂上；因此，在一个周期中无法同时导通所有的上桥臂或下桥臂，故在电池、目标上桥臂开关、目标下桥臂开关以及电机绕组之间所形成的不同回路中的电流方向是不同的，从而产生了交流电流。
由于单向绕组的磁动势是空间呈阶梯型分布，随时间按电流的变化规律交 变的脉振磁动势。将三个单相绕组的磁动势叠加，即为三相绕组的合成磁场。通常加热过程中流入三相绕组电机的三相绕组中的电流，大小并不完全相等，流过其中两相绕组的电流，相位互差180°，不存在相位差的两相电流大小相等。其会导致流过电机绕组中的电流三相不相互对称，且电流频率高导致动力电池在加热过程中电机振动噪声大的问题。
根据本申请的一些实施例，参照图2，图2示出了本申请实施例提供的电机控制装置200的结构示意图。电机控制装置200包括箱体210，在箱体210中容纳有电机逆变器220(图2中未标出)的三个逆变功率模块(221、222、223)和加热功率模块230。电机逆变器220中还包括母线电容224。

根据本申请的一些实施例，参照图3，在箱体210的外壳上还设置有低压接口255；控制板250的输出端通过输出端子连接至低压接口255。这样的设计，使得电机控制装置箱体外壳上的各种接口可以更好地适应整个电机组件的连接。
根据本申请的一些实施例，参照图3，电机中性线接口310、电机多相接口320、电池供电正极接口331、电池供电负极接口332以及低压接口255设置在箱体外壳的同一侧面上。这样的设计，使得电机控制装置箱体外壳上的各种接口可以更好地适应整个电机组件的连接。
