BOSMAL a certified supplier of further laboratory services for the Volkswagen Group
Integration of components in electric vehicles
BOSMAL's offer in the field of integration of components in electric vehicles
-
development of a project to convert combustion vehicles into electric ones
-
conversion of combustion vehicles into electric ones for small series production,
- selection of drive components and supplementary units for electric vehicles (motor with a frequency inverter, battery, charging system, voltage inverters, components of electric supplementary units-heating elements, air conditioning compressor),
- preparation of algorithms of vehicle components control system with the electric drive and steering system integration with participation of the suppliers of main components, such as the motor and battery unit,
- harness design and modifications to the harness of the base vehicle (in the case of conversion),
- arrangement and mounting of powertrain components and supplementary units in the electric vehicle,
- complex tests for the purposes of EC type-approval (small series production).

Services BOSMAL offers in respect to research on electric vehicles
- road tests of functionality and durability under various traffic and climate conditions,
- measurements of geometric dimensions,
- evaluations of cars in terms of security,
- evaluation of traction performance (maximum speed, acceleration capacity from a standstill or from a specific starting speed),
- evaluation of operating properties (vehicle range on different routes, with various driving styles, at sub-zero temperatures),
- tests of the influence of ambient temperature (low, ambient, high) on the efficiency of the electrical energy storage system, its processing system, the mechanical efficiency of the transmission, and the range and performance of the entire drivetrain,
- evaluation of steerability and stability of the vehicle on the road,
- brake assist and steering system assessment and their activation without assist,
- assessment of ventilation and heating systems’ efficiency,
- determination of road load factors via the coast down method,
- measurement of vehicle range on electrical power, at different (non-standard) ambient temperatures,
- measurement of electricity use at various (non-standard) ambient temperatures,
- measurement of power at the car wheels provided by the electrical energy supply system,
- tests of battery charging time,
- evaluation of the amount of batteries power failure while the vehicle is stopped at negative and positive ambient temperatures,
- measurements of temperatures of motor and batteries parts while the vehicle is in motion,
- test result evaluations,
- other tests and R&D activities.
