Description

电动载具的供电电池 技术领域
本发明是有关一种电动载具的供电电池，特别是指将每一个第一电池组其内部所设的多个充电电池分成至少两个以上的第二电池组以并联方式电性连接，再将每一个第一电池组以并联方式相互电性连接而形成一完整的供电电池；借此，当供电电池进行充电时，由外部预设的充电电源与供电电池电性导通，使充电电源的电流及电压以分流方式分别对每一个第一电池组及其内部的每一个第二电池组进行充电。
 背景技术
随着环保意识抬头，节能减碳的概念逐渐受众人所重视，绿色能源的开发与利用成为世界各国积极投入发展的重点。也因为如此，近年来电动载具越来越受欢迎，主要原因是电动载具不需传统燃料（如：石化汽油）作为驱动能源，因此不会排放废气，符合现今节能减碳与环保意识。
电动载具主要是利用所设的电池模组将电能供应至驱动马达，由驱动马达驱动连结电动载具的车轮，让驱动马达将电能转换成动能，借以带动电动载具的车轮转动，达到电动载具不需传统燃料而可行驶的目的。
 技术问题
也因此现今电动载具可行驶的距离，主要取决于电动载具的电池模组的蓄电量；然而，现今电动载具的电池模组的电池容量有限，无法行驶长距离，与现有以传统燃料为动力的载具相比，现今电动载具的行使续航力相差甚远。
除此之外，现今电动载具仍无法普及的缺点在于，现今电动载具的电池模组其充电效果仍不显著，即电动载具的电池模组在充电过程，因现有的电池模组是将内部所设多个充电电池，皆以串联方式相互电性连接，导致现有的电池模组内部多个充电电池会产生充电不平均的现象，同时现有的电池模组在充电过程也容易产生部分电池过热的现象，致使造成电池模组爆炸的可能性；此外也因电池模组内部多个电池充电不平均，导致电池模组在放电过程容易产生部分电池其电量过低的现象，致使造成电池模组损坏的情况。
因此，如何研发一种可使电池能稳定进行充／放电作业，同时避免电池充电过程易产生高温情况，为本发明所欲解决的课题所在。
 技术解决方案
鉴于以上问题，本发明的目的在于提供一种电动载具的供电电池，包括有多个充电电池。由多个充电电池区分成至少两个以上的第一电池组，每一个第一电池组具有预定数量的多个充电电池，而每一个第一电池组内部的多个充电电池再区分成至少两个以上的第二电池组，每一个第二电池组的多个充电电池先以串联方式相互电性连接，之后再将每一个第二电池组以并联方式相互电性连接而构成该第一电池组，使每一个第一电池组具有一预设的电压值及电流量，并且每一个第一电池组设有一第一正／负极接点并与其内部多个第二电池组的并联回路形成导通，最后将多个第一电池组所设的第一正／负极接点以并联方式相互电性连接而构成一完整的供电电池，该供电电池设有一第二正／负极接点并与其内部多个第一电池组的并联回路形成导通。
本发明的改进在于，将每一个第一电池组其内部所设的多个充电电池分成至少两个以上的第二电池组，将每一个第二电池组的多个充电电池先以串联方式相互电性连接，之后再将每一个第二电池组以并联方式相互电性连接而构成第一电池组，最后将每一个第一电池组以并联方式相互电性连接而构成一完整的供电电池；借此，当供电电池进行充电时，由外部预设的充电电源与供电电池的第二正／负极接点电性导通，使充电电源的电流及电压以分流方式分别对每一个第一电池组及其内部的每一个第二电池组进行充电；当供电电池进行放电时，使每一个第一电池组的电压值及电流量汇集于第二正／负极接点后并输出，达到供电电池能稳定进行充／放电作业的目的，同时避免供电电池充电过程易产生高温情况。
其进一步改进在于：还包括有一控制电路，该控制电路设有一第一连接埠及多个第二连接埠，该第一连接埠与该供电电池的第二正／负极接点电性连接，多个第二连接埠分别与充电电源、外部预设的负载电性连接，通过该控制电路对供电电池作电力的输出或输入的调配。
其进一步改进在于：该控制电路具有一预设的电压输出设定值，通过该电压输出设定值对供电电池作限制电压值输出的控制。
 有益效果
本发明的有益效果是：
当供电电池进行充电时，由外部预设的充电电源与供电电池的第二正／负极接点电性导通，使充电电源的电流及电压以分流方式分别对每一个第一电池组及其内部的每一个第二电池组进行充电；当供电电池进行放电时，使每一个第一电池组的电压值及电流量汇集于第二正／负极接点后并输出，达到供电电池能稳定进行充／放电作业的目的，同时避免供电电池充电过程易产生高温情况。

 本发明的最佳实施方式
请先参阅图1、2所示的示意图，本发明揭露一种电动载具的供电电池，包括有多个充电电池1。
多个充电电池1以分组方式区分成至少两个以上的第一电池组2，每一个第一电池组2具有预定数量的多个充电电池1，且每一个第一电池组2内部的多个个充电电池1再区分成至少两个以上的第二电池组11，每一个第二电池组11的多个充电电池1先以串联方式相互电性连接，之后再将每一个第二电池组11以并联方式相互电性连接而构成一组的第一电池组2，使每一个第一电池组2具有一预设的电压值及电流量，另外每一个第一电池组2设有一第一正／负极接点21并与其内部多个第二电池组11的并联回路形成导通，最后将多个第一电池组2所设的第一正／负极接点21以并联方式相互电性连接而构成一完整的供电电池3，而供电电池3设有一第二正／负极接点31并与其内部多个第一电池组2的并联回路形成导通。
本发明列举一实施例，如图1，其中；若使每一个充电电池1其电压值为5Ｖ、电流量为3Ａ时，当每一个第一电池组2设有8个充电电池1，且每一个第一电池组2再平均区分成两个第二电池组11时，则每一个第二电池组11其电压值则为20Ｖ、电流量为3Ａ，又每一个第一电池组2并联有两个第二电池组11，则每一个第一电池组2其电压值则为20Ｖ、电流量为6Ａ；又若供电电池3具有三个第一电池组2时，则供电电池3其总电压值为20Ｖ、电流量为18Ａ。
当供电电池3进行充电时，由外部预设的充电器对供电电池3进行充电，例如：充电器的输出端通过传输线与供电电池3的第二正／负极接点31形成电性导通，使得充电器所输出的充电电源5可与供电电池3电性导通，且充电器所输出的充电电源5（如：输出电压及电流）与供电电池3相匹配，使充电电源5的电流及电压则以分流方式分别对每一个第一电池组2及其每一个第二电池组11进行充电。
当供电电池3进行放电时，由供电电池3的第二正／负极接点31与外部预设的负载6（如：电动马达、电路板、发光元件等）电性连接，使每一个第一电池组2的输出电压值及电流量汇集于第二正／负极接点31后并输出，以对负载6进行供电。
本发明列举另一实施例，如图2，其中进一步包括有一控制电路4，控制电路4设有一第一连接埠41及多个第二连接埠42，第一连接埠41用以与供电电池3的第二正／负极接点31电性连接，多个第二连接埠42用以分别与外部的充电电源5、负载6电性连接，通过控制电路4用以对供电电池3作电力的输出或输入的调配。当供电电池3进行充电时，外部预设充电器的充电电源5可由其中一第二连接埠42传输至控制电路4，控制电路4再通过第一连接埠41将充电电源5传输至供电电池3，使充电电源5的电流及电压以分流方式分别对每一个第一电池组2进行充电。当供电电池3进行放电时，供电电池3的总输出电力由第一连接埠41传输至控制电路4，再由控制电路4将供电电池3的电力调配至负载6，以对负载6进行供电。
值得注意的事，所述控制电路4具有一预设的电压输出设定值，用以对供电电池3作限制电压值输出的控制；当供电电池3进行放电，且供电电池3的输出电压小于等于控制电路4的电压输出设定值时，控制电路4的第一连接埠41则为OFF状态，使得供电电池3停止继续放电，避免供电电池3过度放电，而造成供电电池3损坏。
综上所述，本发明的效果在于：将每一个第一电池组2其内部所设的多个充电电池1分成至少两个以上的第二电池组11，将每一个第二电池组11的多个充电电池1先以串联方式相互电性连接，之后再将每一个第二电池组11以并联方式相互电性连接而构成第一电池组2，最后将每一个第一电池组2以并联方式相互电性连接而构成一完整的供电电池3；借此，当供电电池3进行充电时，由外部预设的充电电源5与供电电池3电性导通，使充电电源5的电流及电压以分流方式分别对每一个第一电池组2及其每一个第二电池组11进行充电；当供电电池3进行放电时，使每一个第一电池组2的电压值及电流量汇集于第二正／负极接点31后并输出，达到供电电池3能稳定进行充／放电作业的目的，同时避免供电电池3充电过程易产生高温情况。
