Simple EVSE, WB (wallbox), DIN, W16
For wiring diagrams and examples please check latest manual for EVSE WB. Firmware and other documentation.
3D model for EVSE-WB is available here: https://www.thingiverse.com/thing:3744887
New board EVSE-W16 (can be understood as Simple EVSE successor) is described in pdf documentation together with EVSE-WB and EVSE-DIN (http://evracing.cz/evse/evse-wallbox/evse-wb-din_20190205.pdf). EVSE-W16 can be delivered also with additional 2pcs 16A relay so you can make 3phase charger! Next option is 1pcs 32A relay (available from August 2020). EVSE-W50 (integrated 4*50A relay) release date is expected during 2019 still in development.
Comparison table with original Simple EVSE
| Simple EVSE | EVSE Wallbox | EVSE DIN | |
 |  |
| |
| can limit the current based on external voltage (for usage with home PV power plant) | no | yes, has 0-5V or optionable 0-10V analog input (NOT ISOLATED) | yes, has 0-5V or optionable 0-10V analog input (NOT ISOLATED) |
| can limit the current based on cable used (PP resistor detection) | no | yes | yes |
| can be mounted inside the connector | yes | no | no |
| has relay onboard (able to drive directly 230V contactor) | no | yes | yes |
| vehicles reported to be working | Nissan Leaf, Citroen Berlingo Electrique, Opel Ampera, Renault Fluence, Mitsubishi Miev, Mitsubishi Outlander PHEV, Citroen C-Zero, Peugeot iOn, eGolf (Type 2) | Tesla S/X, basically all tested with Simple EVSE | Tesla S/X, basically all tested with Simple EVSE |
| known not working vehicles | Tesla, eGolf (older yes), Fiat 500e (?) | none | none |
| recommended to use with | single phase J1772 with small 1phase 20A power relay, with other relay it can be used with Leaf 6.6kW (32A) | 3phase Type 2 (Mennekes) wallbox with external power relay (>6kW), Type 1 | in addition to EVSE Wallbox it has DIN housing |
| kit includes | Simple EVSE board with all parts populated, relay 20A (relpol), small AC/DC converter | EVSE Wallbox board with all parts populated, pluggable terminal blocks | EVSE DIN module with all parts populated, pluggable terminal blocks, different pinout compared to EVSE Wallbox! |
| how to use | need to solder wires on the PCB | just connect phase, neutral, PE, relay output (phase), and control pilot CP | just connect phase, neutral, PE, relay output (phase), and control pilot CP |
| Android application EVSE for configuration, bluetooth connection | no | yes with "modbus" firmware upgrade, header RX, TX, GND, 5V (board sold in 2018+ have all "modbus" firmware which is switched off by default) | non-RS485 version has the same firmware as EVSE Wallbox |
| other options | bluetooth module HC-06, UART cable for PC connection | bluetooth module HC-06, UART cable for PC connection OPTION: RS485 isolated interface (A, B) | |
| Notes | fits on DIN rails, size 2 |
