Description

一种电动车加热电池的控制系统
技术领域：
本发明涉及一种电动车加热电池的控制系统。
背景技术：
现有的给电动车动力电池充电的车载充电机或非车载充电机在输出充电之前都需要检测电池电压(即负载)，而现阶段大部分的加热材料都是阻性负载，充电机在不改变策略的前提下无法正常进行加热。
发明内容：
本发明是为了解决上述现有技术存在的问题而提供一种电动车加热电池的控制系统。
本发明所采用的技术方案有：一种电动车加热电池的控制系统，包括第一继电器、第二继电器、第三继电器、第四继电器、加热膜、动力电池和充电机，所述第一继电器、动力电池和第二继电器串联并形成动力电路，第三继电器、加热膜和第四继电器串联并形成加热电路，动力电路和加热电路并联并组成电池组，所述电池组与充电机并联。
进一步地，所述加热膜为硅胶加热膜。
本发明具有如下有益效果：本发明在不改变现有非加热系统所使用的充电机的控制方式，更加便捷、安全、可靠的实现对加热系统的正常充电及加热充电。
附图说明：
图1为本发明结构图。
具体实施方式：
下面结合附图对本发明作进一步的说明。
如图1所示，本发明公开一种电动车加热电池的控制系统，包括第一继电器K1、第二继电器K2、第三继电器K3、第四继电器K4、加热膜3、动力电池2和充电机1，第一继电器K1、动力电池2和第二继电器K2串联并形成动力电路，第三继电器K3、加热膜3和第四继电器K4串联并形成加热电路，动力电路和加热电路并联并组成电池组4，电池组4与充电机1并联。
本发明中的加热膜3为硅胶加热膜。
当动力电池2处于低温环境(一般＜0℃)时，使用充电机1给电池组4充电，整车检测到动力电池2温度过低，将进入充电加热模式。此时整车控制第一继电器K1和第二继电器K2先闭合，再控制第三继电器K3和第四继电器K4闭合，同时通过控制器(单片机)让充电机1的输出功率等于或略大于加热膜3的功率(针对车载充电机加热膜的功率设计要满足充电机的输出)、充电电压等于或率高于电池当前电压并进入恒压模式，这样就可以达到低温给动力电池2加热的目的。
当温度超过0℃，但小于20℃时，可以适当提高充电机1的输出功率和输出电压，达到一边加热和一边小功率充电的目的。当温度超过20℃时，此时可控制断开第三继电器K3和第四继电器K4，进行正常的充电模式。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下还可以作出若干改进，这些改进也应视为本发明的保护范围。
