Definitions

  • Electric battery comprising thermal conditioning modules encased by a structural matrix
  • the invention relates to an electric battery which is particularly intended for the traction of an electric motor vehicle, or hybrid, that is to say comprising an electric motor driving the driving wheels combined with a thermal engine driving the same or possibly other driving wheels.
  • the energy that a battery is able to supply depends on the energy balance of the various elements as well as their operating temperature. Indeed, the energy that is able to deliver an element increases with temperature and when there are differences in available energy levels in each of the elements, for the same battery, then the battery is said unbalanced. This imbalance greatly affects the performance of the battery both in service life and average energy density because the total energy that can deliver a battery is always limited by the energy of the least charged element, and the Total charged energy is otherwise limited by the most charged element.
  • differences in the level of energy between the elements, causing the imbalance may be due either to differences in the electrical properties of the elements or to variations in temperature of the elements. between these elements.
  • a risk of inversion can then appear for the low states of charge.
  • the chemical compositions of lithium-ion batteries are more or less stable. When subjected to extreme conditions, thermal runaway may occur. For large batteries that are required for vehicles with electrical dominance, this risk is critical, because if the thermal runaway of an element spreads to the entire battery, the energy involved in this runaway becomes very high. .
  • thermal conditioning systems of the elements have therefore been integrated into the batteries.
  • cooling systems have been proposed using air circulation as a cold source. Although many efforts have been made to try to guarantee by this means a temperature distribution as homogeneous as possible within the battery, the fact remains that such systems do not ensure a homogeneous cooling of the elements of the battery.
  • battery solicited power as is particularly the case in applications for electric vehicles and hybrids connectable on the power grid (plug-in English).
  • the thermal dissipation peaks are very large and are a function of the current densities and their variations which, for particular applications, can reach very high values, especially during the phases of strong accelerations, regenerative braking, fast recharge of the battery or highway operation in electric mode.
  • the airflows required to cool the battery cells can only be achieved at the expense of significant element spacing.
  • the liquid may be provided to circulate through plastic cells which are disposed between the battery cells. These cells are insulating and participate in electrical insulation between elements.
  • the plastic bags in which these cells are formed are poor thermal conductors, so they must have a thickness as low as possible in order to ensure approximately correct heat transfer. This results in a maladaptation of the thin walls to the mechanical strength of the elements in the battery.
  • the batteries according to the prior art pose a certain number of problems, notably because of the increase in the degree of hybridization of the thermal vehicles which can go as far as a complete electrification of the drive chain.
  • the batteries then serve not only to assist the vehicles in acceleration phases but also to ensure the movement of the vehicle autonomously over more or less important distances. It is then necessary to increase the energy as well as the electric power of the batteries, which increases the durations of solicitation of the battery, as well as the currents and the average internal resistance. Thus, the energy and thermal power emitted increase, especially as the battery ages.
  • the cost of a battery depends mainly on the number of elements it contains, in other words, its energy. Also, to reduce the impact of the cost of batteries in a vehicle, it seeks to use said batteries over a range of potential as wide as possible in order to extract the maximum energy.
  • the high powers required give rise to large and rapid heating of the battery elements that can induce temperature gradients between the surface and the interior thereof, or even between the elements of the same battery.
  • the increase of the temperature within a battery element induces risks in terms of safety and durability, related to the possible presence of hot spots in the heart of the element.
  • the present invention therefore aims to improve the existing electric batteries by proposing a mechanical and thermal conditioning system that significantly improves the ratio between volume and energy and / or power, as well as the life and safety the battery both from a point of view of chemical behavior and vis-à-vis the constraints in force in the automotive industry, including those concerning the crash.
  • the invention achieves levels of compactness of the system by meeting the requirements of volume density of power and power compatible with the needs of the automotive application, at lower cost and weight.
  • the very low heat transfer resistances possible thanks to the invention make it possible to guarantee the cooling of the battery despite the very high level of compactness.
  • the invention also makes it possible to reduce the temperature within the elements during current draw peaks, and avoids any risk of direct electrical contact of the elements in the event of an impact, which presents an advantage in terms of securing the drums.
  • the efficiency of the thermal management reduces the power consumption and thus guarantees more autonomy for the electric vehicle.
  • the invention proposes an electric battery comprising a plurality of elements generating electrical energy and a conditioning system.
  • said system comprising a bed of thermal conditioning fluid on which said elements are arranged so as to leave a lateral space between the adjacent elements, said conditioning system further comprising a plurality of thermal conditioning modules which are each provided with a fluid flow path between an upstream port and a downstream port, each running path extending in a lateral space with the ports in fluid communication with said bed, said conditioning system further comprising a structural matrix in thermally conductive and electrically insulating polymer resin, said matrix filling the lateral spaces by at least partially coating said generator elements and said conditioning modules.
