Smart Electric Vehicle Charge Controller
|
|
|
|

|
|
|
# What is it?
|
|
|
|
It's an open source EVSE (Electric Vehicle Supply Equipment). It supports 1-3 phase charging, fixed charging cable or charging socket. Locking actuator support (5 different types). And it can directly drive a mains contactor for supplying power to the EV. It features a display from which all module parameters can be configured.<br>
|
|
Up to 8 modules can be connected together to charge up to eight EV's from one mains connection without overloading it.<br>
|
|
The mains connection can be monitored by the (optional) sensorbox or a modbus kWh meter. This allows smart charging.
|
|
Communication between the SmartEVSE(s) / Sensorbox or kWh meters is done over RS485(modbus).
|
|
|
|
|
|
# Features
|
|
|
|
- Fits into a standard DIN rail enclosure.
|
|
- Measures the current consumption of other appliances, and automatically lowers or increases the charging current to the EV. (sensorbox required)
|
|
- The load balancing feature let's you connect up to 8 SmartEVSE's to one mains supply.
|
|
- Two switched 230VAC outputs, for contactors.
|
|
- Powered RS485 communication bus for sensorbox / Modbus kWh Meters.
|
|
- Can be used with fixed cable, or socket and charging cable.
|
|
- Automatically selects current capacity of the connected cable (13/16/32A)
|
|
- Locking actuator support, locks the charging cable in the socket.
|
|
- RFID reader support, restrict the use of the charging station to max 20 RFID cards.
|
|
- An optional modbus kWh meter will measure power and charged energy, and display this on the LCD.
|
|
- Built-in temperature sensor.
|
|
- RGB led output for status information while charging.
|
|
- All module parameters can be configured using the display and buttons.
|
|
- WiFi status page.
|
|
- Firmware upgradable through USB-C port or through the built in webserver.
|
|

|
|
- MQTT API
|
|
- Rudimentary support for home batteries
|
|
- Supporting delayed charging

# Connecting the SmartESVE to WiFi
|
|
|
|
In order to connect the SmartEVSE to your local WiFi network, a temporarily hotspot is created by the SmartESVE to which you can connect using a phone/tablet.
|
|
Here you can then scan for your local WiFi, and enter your Wifi network password. Then the SmartEVSE will use this information to connect to your local Wifi network.
|
|
|
|
The steps to connect the SmartEVSE to Wifi are as follows:
|
|
- in the SmartEVSE menu, go to the option WIFI, then select SetupWiFi.
|
|
- after 10 seconds, a hotspot/access point SmartESVE-xxxx is started. (xxxx is the serial nr of your SmartEVSE)
|
|
- Using a phone or tablet, connect to this access point.
|
|
- You will be asked to enter a password. This password is visible on the top right corner of the SmartEVSE's display. (PW:xxxxxxxx)
|
|
- Once connected you will be able to select your local WiFi network, and enter the password for this network.
|
|
- click SAVE, the SmartEVSE will try to connect to your local WiFi network.
|
|
- Enter the menu of your SmartEVSE again. The SmartEVSE should now display the IP address on the top row of the display.
|
|
- use this IP address in a webbrowser to connect to the webserver of the controller. You can also use http://smartevse-xxxx.local (replace xxxx with the serial nr of your controller)
|
|
|
|
# Updating Firmware
|
|
|
|
Connect the SmartEVSE controller to your WiFi network (using the menu of the SmartEVSE), and then browse to http://IPaddress/update where IPaddress is the IP which is shown on the display.
|
|
You can also use http://smartevse-xxxx.local/update where xxxx is the serial nr of your controller.<br>
|
|
Here you can select the firmware.bin and press update to update the firmware.<br>
|
|
It's also possible to update the spiffs partition from this page. (for v3.0.1 this is not needed)<br>
|
|
After updating the firmware, you can access the status page again using the normal url: http://smartevse-xxxx.local (replace xxxx with the serial nr of your controller)<br>
