Motor Controller Specification

3 Versions are available from September 2016




gensis one 80kW   gensis two 160kW   gensis three 240kW

Designed to be operated at a maximum battery pack of 200 Volts at 400 -1200 Amps, This gives 80 - 240kW of power (107 - 320 Hp) at the motor. 


This is a continuous rating for 1 minute  restricted by the DC Motor temperature. The Kostov K9HV (recommended for gensis one) dc motor has a peak power rating of (conservative) 80kW and a 60 minute rating of 32kW (43 Hp) although this would propel most cars in excess of 80mph on the flat (Power is used during acceleration only eg 10 second bursts or less). 


gensis two should use K9HV, K11HV or K13  Kostov models.  


gensis three only dual motors should be used either the dual 9 or dual 11 in parallel configuration available from Kostov motors (see links)


We do not recommend using low battery pack voltages below 150 Volts due to I2R losses and overheating of motors. In the short term lower battery pack voltages can be used but will impact on battery life if current drawn exceeds the manufacturers recommendation.
