Do you have a ZKETECH EBC-A20 battery tester? Perhaps you don’t like the default software used to control the device. In that case, you might like the alternative whipped up by [Kazhuu.]

A reverse-engineering effort targeted at the EBC-A20 served as the basis for the work. The battery tester is ultimately controlled by a simple serial interface, running at 9600 bps, 8 bits, with odd parity. Armed with a relatively complete understanding of the commands used to control the device, [Kazhuu] was able to whip up a simple web app to control the device instead, using WebUSB to access the device over a USB-to-serial converter, though a desktop version for Linux and Windows is also available. If you’ve got one of these battery testers sitting on your bench, using the app is as simple as pointing your browser here with the device plugged in via USB. Then you can run basic load tests on battery cells and graph the results right on your computer without having to deal with the proprietary software.

Of course, if you don’t like the EBC-A20 battery tester, you could always build your own. If you’re whipping up your own test hardware on the lab bench, don’t hesitate to notify us on the tipsline.

你有一台ZKETECH EBC-A20电池测试仪吗？也许你不喜欢用来控制设备的默认软件。如果是这样，你可能会喜欢[Kazhuu.]搞出的替代方案。

一项针对EBC-A20的逆向工程工作为此提供了基础。该电池测试仪最终由一个简单的串行接口控制，运行在9600 bps、8位、奇校验。在对控制设备的命令有了相对完整的了解后，[Kazhuu]能够编写一个简单的网页应用来替代控制设备，使用WebUSB通过USB转串口转换器访问设备，同时也提供了适用于Linux和Windows的桌面版本。如果你的工作台上正好有这款电池测试仪，只需通过USB插入设备，然后将浏览器指向这里即可使用该应用。然后你就可以对电池单元进行基本负载测试，并在电脑上直接绘制结果图表，而无需处理专有软件。

当然，如果你不喜欢EBC-A20电池测试仪，你总是可以自己动手做一个。如果你在实验室工作台上捣鼓自己的测试硬件，请随时通过提示线通知我们。
