¶ The documentation of the original Electronics
The Chausson X650 uses almost everything from CBE, by default it comes with a CBE PC180-TR controller, it seems to be made to order for the Trigano group, compared to the standard CBE PC180 it has a Light symbol on the second switch instead of the 12V labeling.
The PC180 is a simple Control pannel with a few LEDs and Buttons to show if the Car is charged by the DC/DC Converter while the engine is running, a shore power indicator, 2 buttons which show the charge state of the PB batteries from the Car and the secondary battery as well as a button to show the fresh water level approximately and a butto to dimm the LEDs at night.
No fancy LCD just a few LEDs and buttons.
The basic switching functions are done by a Pushbutton that connects to an input of a tiny STM32 and the corossponding digital outputs of the STM32 are connected to a darlington transistor array that controlls the remotely located relays in the CBE-DS300 fusebox by pulling the Output pin to GND.
There is a 16pin Wire going from the CBE-180 to the DS300. For some reason the exterior light that sits above the rear door on the passenger side is a 12V Sourcing output.
The Pinout is as follows.
Pin:
1. Unknown
2. Unknown
3. Ground
4. Unknown
5. Unknown
6. Light relay control (pulled to GND when on)
7. 12V always on Input
8. Unknown
9. Unknown
10. Unknown
11. GND parallel to Pin 3
12. Exterior light (12V sourcing output)
13. Unknown
14. Waterpump relay control (pulled to GND when on)
15. Unknown
16. Unknown
¶ Under the passenger seat.
Under the Passenger seat you will find space for an 100Ah AGM battery and behind the cover on the back of the seat console you will find a wooden mount that holds a Redarc 1225 DC/DC Converter with an MPPT Tracker input and a CBE BDS-180.
The 140W solar Cell as well as the Car Battery + is connected to the Redarc to charge the secondary battery while driving or via the solar cell on the roof. The Redarc DCDC has a fixed wire loom with 6 cables. The BDS-180 is used to switch between 2 redundant secondary batteries, it does that automatically or via a Remote Switch it can also turn of the 12V Output completely it also has a Shunt to measure the outgoing and incomming current and Wifi to show the Current and battery state in an App.
Redarc wire Map:
Green: External Indicator LED
Blue: Connects to anything thats switched on with the Ignition(start charging from the Car Alternator)
Orange: Config wire for the Battery type
Yellow: Solar Cell Input
Red: Input from the Alternator/Car Battery
Brown: Output to the secondary Battery
