The motor
controller is an important pillar of any electric vehicle.
The controller is basically the computer of the EV which
governs the motor performance of the electric motor.
A well
coordinated system between controller and the motor can help
propel the EV from 0 to 100 within 6 seconds (or less). The
controller controls both manual and automatic drive systems
for starting, stopping, going forward or backward. It
is also capable of governing the speed, regulating torque
and protects against overloads (or faults).
The EVS1
was specifically designed to provide your EV with amazing
pickup and torque unlike any other controllers. The
EVS1 is so powerful that most modern EV batteries would find
it a challenge to match its full operating capacity.
That is why it is important to have certified engineers to
support with the formulas that is suitable to your EV
integration with proper voltage limits.

 |
The
Soliton1 has undergone extensive testing to establish its
current ratings. With no liquid cooling, the controller can
withstand 15-20 seconds of 1000A current before temperature
derating begins.
With liquid cooling (1-2
gpm flow), the controller can deliver 1000A indefinitely.
|
 |
On the
controller's side are two 1/8-27 NPTF ports for liquid
cooling. The controller can be operated without liquid
cooling for a short time at high current.
For longer periods, liquid
cooling is required. Two brass fittings are shipped with the
controller with barbs for 1/4 ID hose. |
 |
Data is
continuously streamed from the controller to its CANbus port
in 100 millisecond intervals.
With the datalogging software
(comes with controller), the data can be viewed. Future
upgrades to the controller (firmware updates, etc.) can also
be sent through this port. |

GENERAL
SPECIFICATIONS & FEATURES |
|
Performance |
1000 Amps: |
The Soliton1 has a continuous
current rating with liquid cooling of 1000A. Running on the
integrated cooling fans only, 1000A is typically available
for 15-20 seconds before thermal derating kicks in. |
|
1400 Amps: |
The Soliton1 can be factory
setup for 1400A race operation upon Evnetics' approval of
your application (special racing warranty applies). |
|
340 Volts: |
8 to 340 Volts maximum pack
voltage. The full charge pack voltage must be limited to 340
Volts. |
|
Features |
Idle: |
PID controlled. Makes
converting vehicles with automatic transmissions, power
steering, A/C, etc. much easier! |
|
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. |
|
"Limp Home" Mode: |
Low pack voltage limit
function protects batteries against over-discharge while
extracting the maximum possible range by limiting motor
current to whatever amount keeps the pack voltage above the
programmed limit. This function provides the greatest
"limp-home" capabilities. |
|
Motor voltage protection: |
User can limit the motor
voltage output to any level.
Current control: Throttle controls motor current (torque)
for a very natural driving feel.
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: |
Spread spectrum switching, or
dithering, is used at low motor currents to maintain precise
control and eliminate jerky starts. |
|
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). |
|
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. |
|
Superior
Construction |
Dyno Tested: |
Every single Soliton1 is put
through a vigorous dyno tested procedure to ensure quality.
|
|
600 Volt IGBT modules: |
Rugged design based on
industrial IGBT modules, not lots of little IGBTs or MOSFETs
in parallel. |
|
Cutting Edge Input Capacitor: |
Ultra low loss polypropylene
film capacitor. No electrolytics to overheat and fail! |
|
Built in Precharge: |
Precharge management and
components are built inside the controller. There is no need
for a external contactor and resistor. |
|
High Efficiency: |
1.5V max. drop at 1000A (0.8V
typical).
Superior Electrical Layout: Internal layout yields very low
noise emissions. |
|
CAE/CAD/CAM: |
Designed and built using the
latest computer-aided engineering, design, and manufacturing
software. |
|
Rugged Enclosure:
|
Great weather ability.
|
|
Forced Air & Liquid Cooled
Heatsink: |
Awesome heat-dissipation
as-is; liquid cooling loops add even more. |
|
Dedicated high power
connections: |
Separate terminals (1/2") for
the battery and motor connections. Makes for a clean and
safe installation. |
|
Connectivity |
Web browser interface: |
Access all settings and update
the firmware with an ordinary web browser!
No additional software or
hardware is required to "talk" to the Soliton. Using a
common ethernet cable and a web browser (internet connection
not required) the controller's maximum voltage and current
can be set. It is also a great tool for visually monitoring
performance in real time. |
|
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: |
Code can be upgraded through
the Ethernet port and is AES encrypted to allow updating to
be done without sending the controller back to us. |
