Abstract

本发明涉及一种启动电动踏板车的方法,其通过除去始终将电力提供到启动电动踏板车的ECU的辅助电池,当可更换电池组被驱动时将电力提供到ECU,提供使用无线通信类型的可更换电池组,并且使用从智能装置接收的无线通信信号作为可更换电池组的驱动信号。

Description

通过使用无线通信方案的可更换电池组启动电动踏板车的 方法
技术领域
本发明涉及一种使用无线通信类型的可更换电池组启动电动踏板车的方法和装置,更具体地,涉及一种通过在可更换电池组中提供近场通信(NFC)模块,无线地驱动电池组,并且直接从电池组提供电力到电动踏板车的电子控制单元(ECU),在没有辅助电池情况下启动电动踏板车的方法和装置。
背景技术
在常规踏板车的情况下,使用诸如汽油和柴油之类的石油燃料,但最近,出现了电力驱动的电动踏板车。电动踏板车是指没有使用石油燃料和发动机,而是使用电池和电动机的踏板车。
这种电动踏板车必须使用智能钥匙或移动电话进行通信认证,以将驱动主电池连接到驱动单元并打开发动机(连接电源)。为此,需要始终将电力提供到与智能装置执行通信认证的电子控制单元(ECU)的辅助电池。
然而,如果电动踏板车长时间未使用,则电动踏板车的辅助电池会自放电,并且在这种情况下,应当理解,辅助电池不能始终将电力提供到ECU,并且电动踏板车无法启动,因此只有通过连接外部电源以打开点火开关或通过电源和辅助电池之间的连接给辅助电池充电,才能启动电动踏板车。
(专利文献0001)KR 2017-0142499 A
发明内容
技术问题
为了解决这个问题,本发明提供一种即使长时间不使用电动踏板车也能启动发动机的方法,其去除电动踏板车的辅助电池并在可更换电池组上形成无线通信(NFC或蓝牙)模块,通过可更换电池组的NFC模块和智能装置之间的直接通信认证来驱动可更换电池组,并且可更换电池组直接将电力提供到电动踏板车的ECU以启动电动踏板车。
技术方案
根据本发明的实施方式,一种使用无线通信类型的可更换电池组启动电动踏板车的方法,包括:在电动踏板车的可更换电池组中提供NFC模块,其中NFC模块接收来自智能装置的无线通信信号;使用接收的无线通信信号作为可更换电池组的驱动信号;当可更换电池组被驱动时,将电力提供到NFC模块,以在NFC模块和智能装置之间执行无线通信认证;当无线通信认证完成时,通过可更换电池组将电力提供到ECU;和使用所提供的电力通过ECU启动电动踏板车。
此外,使用接收的无线通信信号作为可更换电池组的驱动信号包括:使用从智能装置接收的无线通信信号产生可更换电池组的驱动信号;和使用产生的驱动信号驱动可更换电池组的BMS。
此外,在NFC模块和智能装置之间执行无线通信认证包括:将存储在智能装置中的唯一识别号与存储在电动踏板车的NFC模块中的唯一识别号进行比较;和在唯一识别号的比较中,当智能装置和电动踏板车的唯一识别号相同时,通过NFC模块产生启动待机信号。
此外,所述方法进一步包括:将产生的启动待机信号发送到电池组的BMS;和打开ECU电源开关,通过BMS将电力提供到ECU。
根据本发明的实施方式,提供一种无线通信类型的可更换电池组,用于将电力提供到电动踏板车,其中可更换电池组包括NFC模块,NFC模块被配置为从智能装置接收无线通信信号,并将驱动信号施加于可更换电池组,以在可更换电池组被驱动时,通过从可更换电池组接收电力来执行无线通信认证,其中NFC模块包括:接触模块,被配置为通过使智能装置接近以接收来自智能装置的无线通信信号,并将接收的信号产生为可更换电池组的驱动信号;和认证模块,被配置为使用从智能装置接收的无线通信信号来认证可更换电池组。
此外,接触模块包括:能量收集单元,被配置为使用能量收集技术将从智能装置接收的无线通信信号产生为可更换电池组的驱动信号;信号转换单元,被配置为将产生的可更换电池组的驱动信号转换为DC信号;和信号发送单元,被配置为将转换的DC信号发送到可更换电池组。
此外,可更换电池组进一步包括BMS,用于将电力提供到电动踏板车的驱动单元以操作电动踏板车,或控制可更换电池组的充电或放电。
此外,由信号转换单元转换的DC信号激活可更换电池组的BMS。
此外,根据本发明的实施方法,一种装置包括可更换电池组作为电源。
此外,所述装置是选自由电动自行车、电动脚踏车、电动踏板、电动车辆、混合动力电动车辆和插电式混合动力电动车辆组成的组中的任何一种。
有益效果
根据本发明,通过在可更换电池组中使用无线通信技术,可以使用可更换电池组的驱动信号,即使没有始终将电力提供给启动电动踏板车的ECU,也能启动电动踏板车,并且即使长时间不使用电动踏板车,电动踏板车也不会放电。
另外,通过直接从可更换电池组提供必要的电力,可以除去电动踏板车的辅助电池,由此减小电动踏板车的重量,提高燃料效率,降低制造成本。

参考图2,根据本发明的实施方式的电池组20可以包括用于与智能装置30和/或ECU 10无线通信和相互认证的NFC模块100。
具体地,NFC模块100使用无线通信技术与智能装置30无线通信,并使用经由无线通信接收的信号执行无线通信认证。另外,使用无线通信技术与设置在ECU 10中的NFC终端(未示出)执行无线通信,并且使用经由无线通信接收的信号来执行与ECU 10的相互认证。
首先,将描述与智能装置30进行无线通信的无线通信认证的配置。
NFC模块100可包括:接触模块120,在智能装置30接近NFC模块100时接收来自智能装置30的无线通信信号,并使用能量收集技术将接收的无线通信信号转换为电信号;和认证模块140,使用所接收的智能装置30的无线通信信号进行相互认证。

同时,用于与电池组20无线通信认证的唯一识别号可存储在智能装置30中。唯一识别号包括在从智能装置30发送到电池组20的无线通信信号中并用于与电池组20进行无线通信认证。
在无线通信认证中,使用各种已知技术在NFC模块100的认证模块140中执行通信认证。
4)DC-DC转换器40
根据本发明的实施方式的电动踏板车1可进一步包括DC-DC转换器40,用于将电池组20提供给ECU 10的高电力转换为低电力。
当电池组20和智能装置30之间的无线通信认证完成时,BMS 200将电力不断提供到ECU 10。具体地,BMS 200通过控制连接在ECU 10和电池组20之间的ECU电源开关50打开,将电力不断地提供到ECU 10。在这种情况下,从电池组20供应的电力可以是具有高值的电力以作为供应到操作电动踏板车1的驱动单元(未示出)的电力。因此,当具有高值的电力原样提供到ECU 10时,ECU 10可能发生故障。
因此,DC-DC转换器40将电池组20提供的具有高值的电力转换为具有低值的电力,以将低电力提供到ECU 10。
DC-DC转换器40使用各种已知方法将高电力转换为低电力,并将低电力提供到ECU10。
