MiMod® was created to solve several needs for the EV industry. One of EV Instruments’ founders was building his EV project and found that there was nothing available on the market that could monitor the batteries at an individual level and provide detailed battery information from both a charging and discharging perspective. Additionally, he wanted to be able to monitor the EV motor’s RPMs, speed, battery box temperature and other performance parameters. During development, he found that the system, through a console-mounted touch screen, could also allow a driver to control devices and accessories in the EV including headlights, turn signals, door poppers and open/close the trunk. He also made the MiMod system modular and flexible enough to meet the needs of other EV builders and engineers. Today MiMod® is being used in a variety of production applications for EV OEMs as well as working with individuals building their own EV conversion project.

EV Battery Monitoring and Control System (EAA newsletter January 2010)

Being PC-based means having flexibility at its core and while this unit demonstrates a small footprint it draws only minimal power to operate. EV Instruments, a North Kansas City, Missouri. based company started in 2009, manufactures the MiMod™, a monitoring and control system for electric vehicles. While developing updates for his Bradley GT EV, owner Troy Lentz conceived of the MiMod™, which is primarily a battery and electrical control and monitoring system for the car. Its capabilities include, for example, traditional monitoring involving the capture of current levels drawn from the traction pack and the total and individual voltages, displayed in easy to interpret graphical format. While underway - should one or more of the battery modules (or cells, if they are accessible) fall below a predefined threshold a visible and/or audible alarm can warn the driver. This alarming “state” is remembered, as are those preceding it, to be displayed such that action leading up to an alarm can be examined by a technician. Should the situation worsen, the power to the main contactor could be dropped, or a reduced performance mode could be entered. Similarly, if the owner is leaving his EV with a parking attendant, a ‘valet’ mode could be engaged so as to minimize “demonstrations of speed” etc.

MiMod™ provides the EV driver with touch screen controls and the user interface is completely customizable based on the needs of the vehicle owner. Touch screen monitors are available in different sizes and can be mounted either in-dash or on-dash. A version of MiMod™ for commercial fleet trucks is also available from the company. EV Instruments is currently providing small EV OEM companies with MiMod™ so they can provide the latest technology in electric vehicle monitoring and controls
