Developing advanced technologies for flow control <\/h2>\r\n <\/div>\r\n
Electric vehicles require advanced temperature control of the various systems to ensure optimal operation and good energy efficiency. Various fluid systems operate in coordination: <\/div>\r\n
\r\n
    \n
  • The dielectric oil circuit inside the eMotor cools the rotor and stator.<\/span><\/li>\n
  • The cooling system ensures optimum heat transfer between the vehicle\u2019s various systems.<\/span><\/li>\n
  • The battery needs to breathe under normal conditions and to evacuate hot gases in the unlikely event of a thermal overload.<\/span><\/li>\n
  • The refrigerant loop enables heat transfer that would otherwise be impossible, thanks to heat pump systems.<\/span><\/li>\n<\/ul>\n\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n\n\n

    Dielectric oil cooling for electric motors<\/div>\r\n
    \r\n

    In high-performance electronic motors, hot spots can form in the rotor and stator and impair motor performance. Direct dielectric oil cooling removes heat directly from the rotor and stator, and cooling jets target hot spots for efficient heat dissipation. Valves and restrictors can be used to fine-tune the eMotor\u2019s thermal control.<\/span><\/p>\n\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n\n\n

    The cooling system: the vehicle\u2019s heat transfer system<\/div>\r\n
    \r\n

    The coolant (a water-glycol mixture) is the best fluid for transferring heat between the vehicle\u2019s various systems. Complex integrated cooling systems enable a range of high-performance operating modes, from recovering valuable heat in winter to enhanced cooling during ultra-fast vehicle charging. Bontaz coolant valves and distribution manifolds provide the perfect thermal architecture for optimum operation and energy efficiency in all situations.<\/span><\/p>\n\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n

    Breathing and ventilation of the battery pack<\/div>\r\n
    \r\n

    The battery pack must remain a sealed unit, protected from the elements. However, the pressure balance is maintained by our breathing valves. In the unlikely event of a thermal overload, our ventilation valve solutions enable unwanted gases to be evacuated quickly, safely and in a controlled manner.<\/span><\/p>\n\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n\n\n
