Source/WebKit/chromium:

The battery-client (BatteryClientChromium) will notify the client (WebBatteryStatusClient) when to start or stop
sending battery status updates. The client, in response will send the notifications to WebViewImpl, which sends
this update information to the WebCore::BatteryClient, and it triggers the appropriate javascript-callbacks.
The spec is at http://www.w3.org/TR/2011/WD-battery-status-20111129/.
