Electric Vehicle Simulation / EVBot by Cascadia Motion

Required Vehicle Level Inputs (Click to Expand)

By filling out the number of motors and selecting voltage level, motor, inverter, gearing and batteries, EVBot will auto-fill most of the input parameters with initial values for you. You can then tweak those values manually in the next sections to best fit your vehicle configuration.

For helpful tips, roll your mouse over the question marks below.

Number of Battery Modules in Parallel

You can use either of the two battery module selection areas if you only have one battery pack in the vehicle. Even if you have motors on both ends, feel free to use only one battery pack. if you want to look at two pack options simultaneously or if you really plan to have separate front and rear packs then use both!
