SEVCON power limiter without further tweaks.
Current level adjustment (V3.7)
The power command will by default not change or disable the standard power/current limits. If you
want to do this, you need to specify the current level as a fourth parameter (V3.7).
If you set the current level to anything (even 100% = default), the upper safety limits for the torque
and power levels are disabled. So you need to specify a current level to go beyond 70 Nm and/or
16900 W.
On the Twizy 80, you can raise the current level up to 120% translating to 540 A (100% = 450 A).
On the Twizy 45 the maximum level of 330 A is set at 123% (100% = 270 A).
The theoretical upper limits for the torque and power levels are 254% with current control enabled,
that translates to 140 Nm torque and 33 kW mechanical power (37.3 kW electrical power). Due to
the battery / BMS limits these levels can only be reached for a few seconds, so will not provide a
smooth drive experience. Most of the effect will be the power pedal feeling more responsive, but if
you floor it you'll not get the power you expect.
The maximum overall current level has no direct influence on the torque map, other than to allow
higher torque and power levels.
The default flux map (0x4610, torque→current) does not cover torque levels above 70.125 Nm on
the T80 (36 Nm T45), so if you configure a higher torque, the module will install an extended flux
map.
The extended flux map is an educated guess based on my interpretation of the saturation maps
(0x4614, current→inductance). Saturation begins at 130 A and raises linearly from 150 A up.
The T80 default flux map reflects this on the section from 55 Nm up to 70.125 Nm, but the T45
default flux map ends below that point. So my extended T45 version is a translation of the T80 map
with respect to the different saturation levels:
