# Hardware for CCS Sniffing
|
|
|
|
## Homeplug adaptors
|
|
|
|
### Devolo dLAN 200 AVplus
|
|
|
|
|
|
|
|
|
|
Pro:
|
|
* Routes the SLAC traffic from RF port to Ethernet, using the original software (INT6000-MAC-4-4-4405-00-4497-20101201-FINAL-B)
|
|
and unchanged parametrization.
|
|
* Works as CentralCoordinator. This means, it sends out "coordinator packets" which enables the connected car to send out the first SLAC message.
|
|
|
|
Contra:
|
|
* Does not support the read-out of the configuration using the github.com/qca/open-plc-utils.
|
|
* Seems not to be able to send SLAC messages on the RF port.
|
|
|
|
### Devolo dLAN 1200+
|
|
Todo: add picture how to connect the DC power and the RF
|
|

|
### TPlink TL-PA4010P
|
|
This adaptor was suggested by https://openinverter.org/forum/viewtopic.php?p=37085#p37085 and there,
|
|
successfully used to establish a communication to the CCS charger.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Pro:
|
|
* Can be configured as pev and as EVSE, using two different configuration files (created and patches with github.com/qca/open-plc-utils)
|
|
* Is able to transmit and receive the SLAC messages, if the special config files are used.
|
|
|
|
Contra:
|
|
* In original parametrization, does not support SLAC (not routed from RF to Ethernet, and not vice versa).
|
|
* Depending on the configuration, only one direction of the SLAC is routed from RF to Ethernet. Means: Not suitable for sniffing the complete
|
|
SLAC sequence.

Power supply: Originally, it has 12V internal supply. There is a DC/DC step down converter included, which supplies the chipset with 3.3V.
|
|
Works on the original 12V supply line also with 13V/110mA, 10V/120mA, 6V/190mA, and, which reduced RF output power, down to 5V/220mA and even 4V/240mA.
|
|
Just supplying 5V from an USB power bank at the original 12V line works fine. The only drawback is a slightly reduced transmit power, because
|
|
the RF transmitter is connected to the 12V, but is is no issue, because it has anyway much too much transmit power for the CCS use case.
|
|
|
|
How to modify:
|
|
- remove the housing
|
|
- remove the AC power connector parts
|
|
- connect cables to supply the device. Works with 12V, also works with 5V from an USB power bank.
|
|
- connect cables and circuit (1nF and 150ohms in series) for connecting to the pilot line.

## Electric vehicle simulator
|
|
|
|
This device is able to convince an AC charger to deliver power, and also is needed to tell an DC charger, that a car is connected. By closing the "vehicle detected" switch, we pull the CP from 12V to 9V, and the charger will switch to the 5% PWM and starts listening to SLAC parameter request messages.
