Quisque dapibus suscipit sapien. RTD Explorer Features: Bootloading Serial Terminal Real-Time Graphing CSV Export Fault Display RTD Explorer is a real time data acquisition program for the open source cougar based EV motor controllers. With this program you will be able to view and modify parameters of the Cougar based controllers in real time. All available real time information can be graphed for quick visual checking. Data can also be exported for viewing in a program such as Excel. Adam Brunette 774-200-3412 www.EVVette.com Kits By Creator Paul Holmes: http://paulandsabrinasevstuff.com/ Open Source 144V 500A Cougar Controller Open Source Cougar Controller The open source Cougar controller is a project started by Paul Holmes back in December of 2008. When trying to convert a 70’s Super Beetle, He was frustrated in the cost of even the cheapest Curtis controllers. Thus, The Cougar was born. The controller was designed around an ATmega8 AVR microcontroller and was later on upgraded to a ATmega168. Both are still compatible in current firmware. The main logic board was designed to run off the cars 12V accessory battery and is isolated from the traction battery. Fully customizable. Many different controllers with different power stages have been built all over the world, All based on the same logic! 144V 500A for $600* and Less!! High Pedal Lockout (the controller won't start if the accelerator is pressed down) Cycle by cycle hardware over current protection Low voltage controller disable (if the control section power supply drops too low, the mosfet driver is disabled) Controller accepts any pack voltage in the range of 0v up to 144v nominal. 0v won't have a very high top speed. :) Throttle is proportional to current. No jerky starts. Very smooth operation at any speed. It's not yet known how long the controller can run at a given current Controller was able to output 200 amps for about 20 minutes in Phoenix during July, where the ambient temperature was around 108 degF, Without thermal limiting coming on. 8 step thermal current limiting starting at 85°C Full Shutdown at 100°C There is temperature cutback, starting at around 75 degC. All setting’s reprogrammable through serial Connection 16kHz SILENT Switching operation all the time. No high pitch wine when the controller gets hot. Sensorless Motor Overspeed protection. No Tach Sensor needed!! Battery Amps Limiting Amp Hours Used Calculator Built In Contactor Control. Tunable for different Performance *Prices vary depending on who’s kit you buy.
