科沃斯Ecovacs扫地机器人DH35无法充电生活小窍门

早在2020年3月买的科沃斯(Ecovacs)扫地机器人DH35又出现了无法充电的现象,前几天用遥控器控制扫地机器人返回充电座充电时只听到滴的一声接收到了遥控信号,没有听到第二个确认充电的滴声,结果后来发现扫地机器人已经无法开机了,进行了多次尝试,也毫无反应。

今天抱着试一试的最后希望,从机器背面找到了电池仓的位置,在产品铭牌上方,有两个螺丝固定的盖板下面就是。拆开后发现锂电池充电线是卡扣式的连接,也无法手动充电。用万用表测量了一下电压,显示有13.45V,锂电池应该是没问题的。然后就突发奇想,是不是像其他的家用电器一样,手动断电后,机器电路板上残余的静电消失了,故障状态的记忆也就消除了呢?既然这样,那就多等几分钟再把锂电池连接回机器上吧。

顺便拍了两张照片,显示电池生产商是比亚迪,日期为“1951”,一般来讲是表示2019年第51周生产的,不像生鲜类保质期短的产品,电子配件类产品一般均将生产日期精确到批次或一年中的周次。2020年3月1日从京东上购买到的扫地机器人,主机生产日期标示为2020年2月,其原装配套锂电池的生产日期为两个月之前,说明整个生产供应链还是很紧凑的。



过了几分钟后,说干就干,把锂电池充电线连接回机器,按原样安装好锂电池,紧固好电池仓盖板,就迫不及待地将扫地机器人上的电源开关调到“|”位置通电,然后一直按住启动开关,令人兴奋的滴声如约而至。啊哈,简单的电源物理断电操作就恢复了扫地机器人的状态了,真是简单实用啊,过两个小时又可以扫地、拖地打扫卫生了,真是美好生活吧。真希望多些这种生活小窍门,多延长电子产品的寿命,减少浪费,保护环境。

My account at codeberg.org

 I create my account opentiss at codeberg.org in agreement with Give Up GitHub!.

Before I have account on GitHub. But unfortunately I use my domain email as account of GitHub. So when my hosting service server ended his HK company, my domain becomes to unregistered. Then registered by ad sites owner. GitHub need confirm my account by email when I sign in. And I lost my account of GitHub in fact.

I have to find other hosting service. And now I use a2hosting outside of some dangerous countries as you known. I can only use a new domain opentiss.uk and give up used over fifteen years old domain.

a2hosting is fit to me and is the best web hosting for me. You can register account and normal visit in some dangerous countries. That's important to me. As developer I need visit Internet from dangerous local network. I used Unmanaged VPS Hosting Runway 2 for triennially term. That is cheap for software developer. If you are interesting to a2hosting, I share my refer. You should have discount with the refer.
