This is the BCU and LC (Battery Control Unit and Line Charger), side by side.
The Line Charger is enclosed in a sealed brass and aluminum case. It has gaskets and is designed for automotive installation, virtually weather-proof.
The Line charger has three connections. One is for line input (208vac to 240vac), one for charge output (288vdc nominal (actually up to 350vdc)), and a control interface (connected to and used by the BCU).
See also the scanned document which details the connection above.
With documentation for the 8-line interface above, it should be possible to control the line charger without using the BCU. Here are some pictures of the BCU and Line Charger internals--
I have two each of these (one set from bus #135, the other from #168). I have the wire harness sets for each (some wires were cut, but I have all the connectors). I intend to use one set for my project. I was planning to use the other set (as spare, backup, parts), but I am willing to sell one set to an engineering 'partner' (sharing information).
The BCU uses the Motorola 'Coldfire' processor. It supports a CAN interface for communicating with a PC-host. I am reverse-engineering this as a hobby project, but there is no documentation for it (other than a complete pin-out of each of the plugs/jacks on its connections).
