Definitions

  • the present invention generally relates to heat exchangers.
  • the invention relates to heat exchangers for automobiles. More particularly, the invention relates to a heat exchanger that can be used for low-pressure applications as well as for high-pressure applications.
  • thermal control When the battery is operated at a low temperature, the power output will be reduced due to the suppression of the electrochemical reactions, while a high temperature will accelerate corrosion, thus leading to reduced battery life. Other than that, the temperature range and uniformity in a pack are significant factors for obtaining optimum performance from an EV battery pack. An excessive rise in the local temperature in Li-ion batteries will cause a reduction in the life cycle and may lead to the occurrence of thermal runaway in an individual cell or in the entire battery pack. Thermal runaway is a failure mode in the battery and it may cause a fire and an explosion if the thermal management system in the battery is ineffective.
  • Cooling method for the Li-ion battery to ensure that it has an effective thermal management system.
  • There are several types of cooling methods for Li-ion batteries such as air cooling, liquid cooling and the use of phase change materials.
