Performance:

• 1000 Amps: The Soliton1 can deliver 1000A at all duty cycles at up to 300V (slight derating above 300V). If liquid cooling is used that is a continuous current rating! Even with just the built-in fans/heatsink you can get 1000A for 15-20 seconds every 90-120!

• For drag racing applications the current limit can be increased to as much as 1400A upon EVnetics approval of your use and setup (a special racing warranty must be agreed to in writing).

• 300 Volts: The Soliton1 can operate on 10V minimum to 342V maximum.


Features:

• Battery pack protection: both maximum current and minimum voltage on the battery side are programmable - protect your pack from abuse while extracting the maximum performance and range from your pack.

• Motor protection: motor voltage, current and total power can be limited; with separate limits for when in reverse.

• Adjustable switching frequency: Losses in any controller go up with switching frequency; the Soliton1 lets you choose between higher performance and efficiency (8kHz) or guaranteed silence at all current levels (14kHz).

• Smooth starts: Dithering is used at low motor currents to maintain precise control and eliminate jerky starts without resorting to a huge drop in switching frequency.

• Idle: A world's first for EVs! Makes converting vehicles with automatic transmissions, power steering, A/C, etc. much easier!

• Adjustable acceleration rate: The rate at which motor current is allowed to rise is adjustable from a tortoise-like 100A per second to a tire-boiling 25,000A/s (functions essentially like traction control).

• Built-in Main Contactor w/ Auto-Pre-Charge: Precharge management and main contactors are inside the controller.

• Protected against wiring errors: All input terminals protected against reverse and over-voltage. All output terminals protected against short-circuit and inductive kickback (diodes recommended across all coils anyway). Even the battery pack terminals are protected against reverse polarity and overvoltage!

• 3-wire throttle input: Accepts a 0-5V signal from a pot, automotive TPS or Hall effect pedal, etc.. The range is calibrated and "off" can be compensated for drift. Polarity can be inverted and a broken throttle wire detected.

• Tachometer input/ouput: Compatible with industrial proximity sensors (1, 2, 4, 6 per turn) to protect against motor over-speed and necessary for idle. Tach output drives a 4cyl or 6cyl tachometer gauge regardless of input pulses/turn.

• Brake input: inhibits the throttle when active for additional safety.

• Three programmable inputs: Reverse and motor over-temp so far, with sport/econo mode and cell-level low voltage cutoff coming soon

• Three programmable outputs: Meter drivers to display motor and battery amps, power, etc. Switching twin motors between series/parallel (coming soon).

• Error light output: for reporting errors to the driver via the existing "Check Engine" light or other 12V indicator.


Connectivity:

• Web browser interface: Access all settings and update the firmware with an ordinary web browser!

• Data acquisition: Performance data is continuously streamed to the Ethernet port (UDP format) at 0.1s intervals. A basic logging program is available and the data format is open source.

• Firmware upgrades: new features can be added to the Soliton1 without removing it from the vehicle - just upload the encrypted firmware through the web interface (or optional "speed updating" program) and reboot!
