[0002] a)目前市场上的充电器只能显示当即情况下电池组的电量,只能起到要不要马上充电的提示作用,电量不够时,提示用户要马上充电,实现这ー过程,只需配设具有检测、对比及显示功能的微处理器即可,即不具备记忆功能,记忆充电器及电池组的使用过程及エ作情況。
[0003] b)电动车充电器,也均不能记忆充电器及电池组的使用过程及工作情况的功能。 当车厂卖出整车后,若用户没有按要求对电动车的电池组正确地使用和充电,如电池长期工作在没充满电的情况,或低电压贮存时间过长,会引起电池过早老化,容量快速减低,内阻増大等问题。当此类问题出现后,用户会提出在保修期内电池损坏要求保修,由于没有记忆的功能,车厂便无法提供证据证明是因为用户没按使用及维护要求导致电池过早损坏。
[0004] c)目前市场上的充电器,均没有万年历的功能,也就不能记录充电器或电池组エ作的具体时间,也就无法提供证据证明是因为用户没按使用及维护要求导致电池过早损坏。
[0005] d)目前市场上的电动车充电器,均不能自动对电池进行均衡充电.需手动设置均衡充电。
发明内容
[0006] 本发明g在针对现有技术的上述不足,推出具备记忆功能的车载式电动车充电器。其能自动记忆充电器和电池组使用和维护的工作数据至少3年时间,当厂家在维修车辆时,只需要将电脑连接到充电器机内的连接器,便可用电脑读出充电器的贮存在其芯片中的由出厂到维修期间的工作数据;可以在用户完成一定周期的充电后,自动对电池进行均衡充电,使电池组的參数更加均衡。
[0007] 为了实现上述目的,完成上述任务,本发明具备记忆功能的车载式电动车充电器采用如下技术方案:
[0008] 构造本发明具备记忆功能的车载式电动车充电器,包括AC输入电路、功率因素校正电路、高压直流电路、DC-DC转换电路、输出控制电路及充电输出端子,AC输入电路的输出端连接功率因素校正电路的输入端,功率因素校正电路的输出端连接高压直流电路的输入端,高压直流电路的输出端连接DC-DC转换电路的输入端,DC-DC转换电路的输出端连接输出控制电路的输入端,输出控制电路的输出端连接充电输出端子,由充电输出端子连接至电动车电池组,向电动车电池组充电;
[0009] 还包括MCU芯片、电池组电压检测电路、工作数据存储模块、车辆控制讯号连接端ロ、万年历芯片、数据读取端ロ及辅助供电电路;电池组电压检测电路分别与充电输出端子及MCU芯片连接,从充电输出端子获取数据,再将数据输入MCU芯片;工作数据存储模块与MCU芯片连接,将来自MCU芯片的数据存储,也可以向MCU芯片输出存储的工作数据;车辆控制讯号连接端ロ与MCU芯片连接,从MCU芯片获取数据;万年历芯片与MCU芯片连接;数据读取端ロ与MCU芯片连接,两者进行互动,即数据读取端ロ可以从MCU芯片读取所需要的数据;辅助供电电路的输入端连接高压直流电路的输出端,再向DC-DC转换电路、输出控制电路、MCU芯片及工作数据存储模块供电;辅助供电电路还与车辆控制讯号连接端ロ连接;
[0010] MCU芯片通过电池组电压检测电路监测到电池组的电压,并自动记录电池组的充电及放电数据存储于所述工作数据存贮芯片中,其记录的数据至少包括:①.正常完成充电过程的次数、放电后未及时充电的次数及发生的时间、充电未充满便关电停止充电的次数及发生时间、电池组电压达到低压保护的次数及发生的时间。
[0011] 对上述技术方案进行进一步阐述:
[0012] 当要读取充电器贮存的数据时,将计算机通过联机连接到所述数据读取端ロ,SP可调出全部的存贮记录或按需要调出相关的存贮记录。
[0013] 通过存贮于所述工作数据存贮芯片的数据,MCU芯片可以在电池完成一定次数的充/放电后,自动启动对电池进行均衡充电模式,自动修复平时充放电产生的电池单体间的不均衡。
[0014] 所述MCU芯片通过所述电池组电压检测电路实时监测电池组的电压,可以对电池组实施过放电保护,包括当电池组的电压降到一定的值并持续一定的时间,MCU便发出信号来降低车速,当电池组电压继续降低到另ー个更低的电压吋,MCU便可以发出信号来让车辆停止运行.以达到保护电池组,避免过放电导致电池组损坏。
[0015] 本发明具备记忆功能的车载式电动车充电器,其有益效果在于:

[0018] 其三,能配合车辆制造厂强制用户对电池低压进行保护性操作,即具有电池低压保护功能。当电池电压降低到一定的范围吋,自动控制电动汽车的油门,使车辆工作在慢速的状态,如果车内电池电压继续降低,充电器将发出控制信号,控制车辆使其停车。这样可确保电池组不会因为过放电受到损害。
[0019] 其四,用途广,可广泛应用于电动叉车、高尔夫球车、观光车及电动汽车等交通运输工具。
附图说明
[0020] 图I为本发明电路方框示意图。具体实施方式 [0021] 下面,结合附图介绍本发明的具体实施方式。
[0022] 如图I所示,本发明具备记忆功能的车载式电动车充电器,包括AC输入电路、功率因素校正电路、高压直流电路、DC-DC转换电路、输出控制电路及充电输出端子,AC输入电路的输出端连接功率因素校正电路的输入端,功率因素校正电路的输出端连接高压直流电路的输入端,高压直流电路的输出端连接DC-DC转换电路的输入端,DC-DC转换电路的输出端连接输出控制电路的输入端,输出控制电路的输出端连接充电输出端子,由充电输出端子连接至电动车电池组,向电动车电池组充电;
[0023] 还包括MCU芯片、电池组电压检测电路、工作数据存储模块、车辆控制讯号连接端ロ、万年历芯片、数据读取端ロ及辅助供电电路;电池组电压检测电路分别与充电输出端子及MCU芯片连接,从充电输出端子获取数据,再将数据输入MCU芯片;工作数据存储模块与MCU芯片连接,将来自MCU芯片的数据存储,也可以向MCU芯片输出存储的工作数据;车辆控制讯号连接端ロ与MCU芯片连接,从MCU芯片获取数据;万年历芯片与MCU芯片连接;数据读取端ロ与MCU芯片连接,两者进行互动,即数据读取端ロ可以从MCU芯片读取所需要的数据;辅助供电电路的输入端连接高压直流电路的输出端,再向DC-DC转换电路、输出控制电路、MCU芯片及工作数据存储模块供电;辅助供电电路还与车辆控制讯号连接端ロ连接;
[0024] MCU芯片通过电池组电压检测电路监测到电池组的电压,并自动记录电池组的充电及放电数据存储于所述工作数据存贮芯片中,其记录的数据至少包括:①.正常完成充电过程的次数、放电后未及时充电的次数及发生的时间、充电未充满便关电停止充电的次数及发生时间、电池组电压达到低压保护的次数及发生的时间。
[0025] 当要读取充电器贮存的数据时,将计算机通过连接线连接到所述数据读取端ロ,即可调出全部的存贮记录或按需要调出相关的存贮记录。
[0026] 通过存贮于所述工作数据存贮芯片的数据,MCU芯片可以在电池完成一定次数的充/放电后,自动启动对电池进行均衡充电模式,自动修复平时充放电产生的电池单体间的不均衡。
[0027] 所述MCU芯片通过所述电池组电压检测电路实时监测电池组的电压,可以对电池组实施过放电保护,包括当电池组的电压降到一定的值(例如I. 8V/单元格)并持续一定的时间(例如:10秒钟),MCU便发出信号来降低车速,当电池组电压继续降低到另ー个更低的电压时(例如I. 7V/単元格),MCU便可以发出信号来让车辆停止运行.以达到保护电池组,避免过放电导致电池组损坏。
[0028] 本发明中的万年历芯片和工作数据存贮芯片,充电器出厂时由车辆制造厂校对时间,以便能在出厂后正确记录电池组及充电器的使用日期和时间。
[0029] 本发明的工作过程如下:
[0030] A、当本发明的充电器的AC输入连接到市电对电池充电时.本发明的充电器内辅助供电电路负责对所有的控制部分供电,MCU芯片和万年历芯片通讯以获取每个事件发生的时间,工作时MCU芯片先检测DC输出端子是否有连接到电池上,和检查电池的电压是否正常,如果没有连接电池或电池电压不正常,本发明的充电器都将自动关断输出;如果连接正常,本发明的充电器的MCU将按照出厂设定的程控对电池进行充电,并对充电过程进行监控,如果充电过程能够按已定的程序将电池充满,MCU将会记录一次正常充电到存储模块中。
[0031] B、当正常充电的次数达到一定的次数(例如30次)MCU芯片将自动进入均衡充电模式,自动修复平时充放电产生的电池单体间的不均衡。
[0032] C、如果开始充电但没能完成充电用户便停止充电将电车开出去使用,MCU芯片也将记录这次为一次不正常充电保养并记录发生的时间。
[0033] D、当本发明的充电器没有连接到市电上,电动车的点火开关也没有点火时,本发明的充电器工作在休眠状态,这时本发明的充电器不会用蓄电池的电能,也不检测电池组的电压,但本发明的充电器内的电池能让万年历芯片继续运行,不会因为外面没有电能而不工作,这样避免了本发明的充电器连接到电动车上后会放电对导致电动车在停用或海运等时间造成电池损坏,而一旦电车的点火开关打火,本发明的充电器的辅助供电电路便会从电池组取电转换为各控制电路,MCU芯片上电后通过电池组电压检测电路监测到电池组的电压,当电池组的电压降到一定的值(例如1.8V/单元格)并持续一定的时间(例如:60 秒钟),MCU便会记录下电池组的电压及发生的时间,同时MCU会发出ー个讯号给电动车控制器,让电动车开始減速,当电池组电压继续降低到另ー个更低的电压时(例如1.7V/単元格),并持续一定的时间(例如:30秒钟)MCU便又记录当时的电池组电压及发生的时间,同时发出另ー个讯号切断电动车控制器的控制电源,让电动车停车。
[0034] 由于本发明的充电器中有万年历和工作数据存储模块、车辆控制讯号连接端ロ、数据读取端ロ,充电器在出厂时由エ厂例如按北京时间设定好日期和时间,以后MCU只要检测到下述需要记录的条件成立,都会记录在存储模块中。其记录的数据包括:正常完成充电过程的次数;放电后未及时充电的次数及发生的时间;充电未充满便关电停止充电的次数及发生时间;电池组电压达到低压保护的次数及发生时间。
[0035] 以上所述,仅是本发明的较佳实施例,并非对本发明的技术范围作任何限制。本行业的技术人员,在本技术方案的启迪下,可以做出一些变形与修改,凡是依据本发明的技术实质对以上的实施例所作的任何修改、等同变化及修饰,均仍属于本发明技术方案的范围内。
