Description

State of the art

It is foreseeable that both in stationary applications, for example in wind turbines, and in mobile applications, for example in electric vehicles (EV) or hybrid vehicles (hybrid electric vehicles, HEV), as rechargeable electrical energy storage (EES) increasingly new Battery systems (accumulator systems), for example with lithium-ion batteries, lithium-polymer batteries or nickel-metal hybrid batteries will be used.

The battery systems must meet very high requirements in terms of usable energy content, charge / discharge efficiency, reliability, life and unwanted capacity loss due to frequent partial discharge.

A battery system includes a plurality of battery cells. Due to their internal cell resistance and the electrochemical processes that take place, the battery cells heat up during charging and discharging. The battery cells can be connected in series (series) to increase the voltage and / or connected in parallel to increase the maximum electric current. In this case, the battery cells can be combined to form battery units or battery modules. When used to drive vehicles, for example, about 100 battery cells (as a traction battery) can be connected in series or in parallel. For example, in a high voltage battery system, the total voltage may be 450V or even 600V.

The permissible for the operation of the battery cells temperature range is typically between -30 ° C and +70 ° C, preferably between +5 ° C and +35 ° C. In the lower range of the operating temperature, the performance of the battery cells can be significantly reduced. At temperatures below about 0 ° C, the internal resistance of the battery cells increases sharply, and the performance and efficiency of the battery cells continue to decrease as temperatures continue to fall. In this case, an irreversible damage to the battery cells can occur. Even if the operating temperature is exceeded, the performance of the battery cells may decrease significantly. At temperatures above approx. 40 ° C, the service life of the battery cells is reduced. In this case, an irreversible damage to the battery cells can also occur. Furthermore, the allowable for the operation of the battery cells temperature difference (temperature gradient) in a battery cell and / or within a battery module or a battery typically between 5 Kelvin and 10 Kelvin. For larger temperature differences, different areas of a battery cell or different battery cells of a battery module or a battery can experience different loads or even (partially) overloaded and / or damaged. Furthermore, due to temperature differences and / or temperature changes, there is a risk of the formation of condensation in the battery. The damage can lead to an accelerated aging of the battery cells or a thermal runaway of the battery cells, which represents a danger to humans and the environment.

In a hybrid powertrain of a vehicle, lithium-ion high-performance battery cells are operated with a very high dynamics. During short-term peak loads caused, for example, by recuperation of braking energy during braking or boost assistance during acceleration, the battery cells must in a very short time a high performance (when charging) record or deliver (on discharge). Due to the internal resistance of the battery cells, these short peak loads lead to significant heating of the battery cells. The efficiency of the battery cells when charging or discharging is very high (about 95%); Nevertheless, the resulting waste heat is not negligible. At a traction power of, for example, 60 KW results in a loss of 5%, a power loss of 3 KW. Furthermore, for example, in the summer months or in warmer regions, outside temperatures, which may be 40 ° C and more, outside the allowable temperature range, so that the battery cells without cooling the required life of, for example, ten or 15 years can not reach.

To ensure the safety, function and life of the battery module or battery system, it is therefore necessary to operate the battery cells within the specified temperature range. On the one hand arises, as described above, during operation of the battery cells heat that must be dissipated to prevent heating of the battery cells above the critical maximum temperature. On the other hand, it may be necessary to heat the battery cells at low temperatures to a minimum temperature. To maintain the predetermined temperature range, the battery module or battery system is heated, d. H. cooled or heated as needed, the cooling is usually required more often than the heater.

Alternatively, the steps may be performed serially one after the other. Here are the steps 710 - 714 and then the steps 720 - 714 be executed, or vice versa. Furthermore, the steps for carrying out the method 70 be varied. For example, the connection of the connection elements 470 ₁ , 470 ₂ or connecting olives with the openings 460 ₁ , 460 ₂ after closing the channel 450 with the second sheet 500 or even just before or during the assembly of the battery module 10 be done in a battery, a battery system, a vehicle or a system.

Finally, it is noted that terms such as "comprising" and "having" or the like do not preclude that further elements or steps may be provided. It should also be noted that "a" or "an" does not exclude a multitude. In addition, the features described in connection with the various embodiments may be combined with each other as desired. Finally, it is noted that the reference signs in the claims should not be construed as limiting the scope of the claims.
