Dilithium Design EV Display

Dilithium Display

New Item!

For use with the Dilithium Design Battery Management System, this Electric Vehicle Display is extremely handy for showing battery voltages, state of charge, and can even be used to easily configure voltage settings in the BMS with it's Touchscreen interface!  Packed full of information, right at your fingertips. 

Optional Hall Sensor is used to show current draw in amps in real time. Hall sensor is a DHAB S-44 (-420a - +230a)

Optional analog fuel gauge is availalble online, see details in manual. 

Actual display area is approximately 2.55" tall by 1.91" wide, plus the black bezel for a total size of 3.89" x 2.86"


When I first installed this display I considered it as a secondary display which I would refer to as needed. However, after using it for a period of time I came to realize it would be used as a primary display that would be placed directly in front of me for reference while driving. While it seems small at first it now actually seems like the perfect size for my dash and is placed next to my GPS speedometer with similar size readings.

The main screen provides a lot of information but it seems balanced and easy to read. At the top of the display is the digital fuel gage shown as a bar graph. Just below the bar graph is a digital display of the total battery pack capacity, which you can set to your individual pack size, and the amount of capacity left. Below the fuel gage bar graph is a display of both the pack voltage and the amp draw which are show in digital and bar graph forms. The amp draw is especially useful in determining the amp draw under varying conditions such as hard acceleration, normal freeway driving or going up or down grades. Also on the main screen is a bar graph at the bottom which displays the range between the low voltage and the high voltage cutoffs you have set for the battery pack and cell type for your vehicle. On this bar graph is a display of the range of cell voltages while driving. Below this bar graph is the digital display of your average cell voltage. Under varying conditions you can visually see a graphical representation of the range of the voltages on your individual cells which will increase under load.

From the main display screen you can move through the touch screen to other features. What I especially like is I can change various settings simply by using the touch screen with no need to connect a lap top computer. One of the screens shows the history of the charging cycles with information on the minutes charged, the reason for the charge termination, the maximum voltage during the charge and the watt hours added during the charge. In conjunction with my GPS speedometer I use the history to determine the average miles per kWh so I can manually calculate my driving distance based on my estimate of battery pack capacity.

If the display is connected to a BMS you will be able to adjust various settings on screen and you will be able to see the voltage of all the individual cells. If you detect a widening of the average cell voltage bar graph on the main display, or if you are experiencing a cut off from an individual cell falling below the low voltage cut off level, you can actually locate the problem cell on screen and determine where it is in your pack.

If needed you can connect a lap top computer directly to the display for adjusting additional settings or saving data to the lap top. Another nice feature is you can connect the display to an analog fuel gage if you want to keep the look of your dash in your vehicle. The price for the display is vary reasonable for the amount of data displayed and varying configurations it will handle. Set up is fairly simple especially with the good documentation provided.
