可以理解，该充电器10还可兼容非智能型电池，例如，该电池20还可以为不具有自平衡功能的电池。该非智能型电池包括多组串联或并联的电芯。此时，所述充电器10还包括平衡充接口17及电芯电压采集单元18。其中，所述平衡充接口17用以通过线缆电性连接至所述非智能型电池，进而对所述非智能型电池的各组电芯进行平衡充电控制。所述电芯电压采集单元18电性连接所述控制电路15及平衡充接口17。如此，所述电芯电压采集单元18可通过该平衡充接口17电性连接至所述非智能型电池，进而与所述非智能型电池进行通信，使得所述电芯电压采集单元18可通过该平衡充接口17获取所述非智能型电池的充电电压信息。如此，所述控制电路15可根据该电芯电压采集单元18采集到的非智能型电池的充电电压信息设定相应的充电信号，再控制所述DC-DC转换单元123输出该设定的充电信号，并通过该电源输出接口13输出所述设定的充电信号，以对所述非智能型电池进行充电。
当然，在其他实施例，若所述非智能型电池也具有电池设计信息，则所述控制电路15也可通过信号接口14与所述非智能型电池进行通信，进而获取所述非智能型电池的充电信息，并对其进行识别和认证。也就是说，只有当识别通过的非智能型电池才能被允许充电或者大电流充电。而当所述控制电路15根据该非智能型电池的充电信息判断所述充电器10无法对所述非智能型电池进行充电，即所述充电器10与所述非智能型电池的型号并不匹配时，所述控制电路15可控制所述DC-DC转换单元123停止输出充电信号，进而保护该非智能型电池，以防止对该非智能型电池造成损伤，甚至造成爆炸。
可以理解，在其他实施例，所述控制电路15还可根据该电芯电压采集单元18采集到的非智能型电池的充电电压信息，通过该平衡充接口17控制非智能型电池的各组电芯的当前电压。具体地，当所述电池20为非智能型电池时，该充电器10还包括电芯平衡单元19。所述电芯平衡单元19电性连接所述控制电路15及平衡充接口17。由于非智能型电池在充电过程中，可能导致各组电芯的充电电压并不一致。因此在所述电芯电压采集单元18采集到所述非智能型电池中各组电芯的电压信息后，所述控制电路15可根据各组电芯的电压信息启动所述电芯平衡单元19，例如，使得所述电芯平衡单元19对非智能型电池中电压较高的电芯进行放电，以平衡所述非智能型电池内的各组电芯的充电电压，进而使得非智能型电池内的各组电芯都具有最满容量。
显然，上述充电器10可同时适用于智能型电池及非智能型电池，即既能对智能型电池进行充电，也可以对非智能型电池进行充电。如此，无需再针对每一款电池20单独设置一款相应的充电器10，因而实用性较高。另外，该充电器10还可对智能型电池及非智能型电池进行智能识别及认证，从而确保该充电器10仅对相匹配的所述电池20进行充电，如此可有效保护电池20，延长该电池20的使用寿命，进而防止出现安全事故。
