Complete system for electric vehicle propulsion



Complete system for electric vehicle propulsion
Доставчик: IKEM Corp.

These types of electric propulsion are appropriate for conversion of ordinary internal combustion engine /ICE/ vehicle into electric vehicle /EV/ and also for newly designed electric vehicle build-up.

Electric propulsion system includes three type sizes of electric powerwith the relevant components - electric motor and controller:

  • 50/100 kW/nom/max./, 300V
  • 25/50 kW, 144V
  • 70/120 kW, 350V

\\\"\\\\\\\\\\\\"\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"\\\\\\\\\\\\"\\\"

Areas of use:

For the conversion of a standard vehicle into electric one; for newly designed electric vehicle build-up and other electric vehicle such as – electric platforms, electric locomotives, electric forklifts for larga-capacity, specialized electric vehicles for airports, major port centers and logistic centers and others.

Electric vehicles propulsion systems are intended for single-engine electric propulsion for vehicles like cars, minivans, vans, trucks with total weight/curb weight plus payload /1500-6500kg./

With these types of propulsions can be implemented engined cinematic schemes for traction drive which increases the load capacity of the EV.

Controller`s software adapts the specific characteristics of the electric motors with technical and dynamic characteristics of the transport vehicle.

Thus achieving maximum energy efficiency in the EV exploitation in different models of the electric propulsion.

Except the efficient management of the electric motor the software allows:

-   Choosing appropriate load characteristics of the propulsion complied with the mechanic construction and cinematic scheme of the EV. This limits the dynamic overloading, which is extremely important in conversions.

-   Choosing different target modes of exploitation; option to set limits in acceleration, stopping and movement

-   Option to manage a specialized display to control the propulsion

-   Communication option with other systems of the EV

-   Monitoring of parameters by different data inputs and control outputs

Sample of graphics for achieved different speeds in different modes of electric propulsion depending on the weight of the EV and on the slope – Graphics 1, 2 and 3.
