Description
Die Erfindung betrifft eine flüssigkeitsgekühlte Busbaranordnung, ein Batteriemodul und ein Verfahren zum Betreiben einer flüssigkeitsgekühlten Busbaranordnung.The invention relates to a liquid-cooled busbar arrangement, a battery module and a method for operating a liquid-cooled busbar arrangement.
Unter dem Begriff Busbaranordnung wird eine Anordnung von einem oder mehreren Leitern verstanden, die zum Sammeln und/oder Transportieren und/oder Verteiler von elektrischer Energie dienen.The term busbar arrangement is understood to mean an arrangement of one or more conductors which are used to collect and / or transport and / or distribute electrical energy.
Aus der
Die erfindungsgemäße flüssigkeitsgekühlte Busbaranordnung umfasst
- a) einen ersten leitfähigen Körper mit
- - einem ersten durchgängigen Hohlraum,
- - einer ersten Ausformung zur mechanischen, elektrischen und thermischen Anbindung einer ersten Batteriezelle und
- - einer zweiten Ausformung zur mechanischen, elektrischen und thermischen Anbindung einer zweiten Batteriezelle,
- b) einen zweiten leitfähigen Körper mit
- - einem zweiten durchgängigen Hohlraum,
- - einer dritten Ausformung zur mechanischen, elektrischen und thermischen Anbindung einer dritten Batteriezelle und
- - einer vierten Ausformung zur mechanischen, elektrischen und thermischen Anbindung einer vierten Batteriezelle und
- c) ein elektrisch isolierendes Verbindungselement mit einem dritten durchgängigen Hohlraum,
wobei das Verbindungselement zwischen dem ersten leitfähigen Körper und dem zweiten leitfähigen Körper so angeordnet ist, dass der erste, der zweite und der dritte durchgängige Hohlraum einen zusammenhängenden Kühlkanal formen.The liquid-cooled busbar arrangement according to the invention comprises
- a) having a first conductive body
- - a first continuous cavity,
- - A first formation for the mechanical, electrical and thermal connection of a first battery cell and
- - a second formation for the mechanical, electrical and thermal connection of a second battery cell,
- b) with a second conductive body
- - a second continuous cavity,
- - A third formation for the mechanical, electrical and thermal connection of a third battery cell and
- - A fourth formation for the mechanical, electrical and thermal connection of a fourth battery cell and
- c) an electrically insulating connecting element with a third continuous cavity,
wherein the connecting element is arranged between the first conductive body and the second conductive body such that the first, the second and the third continuous cavity form a coherent cooling channel.
Dadurch, dass der erste, der zweite und der dritte durchgängige Hohlraum einen zusammenhängenden Kühlkanal formen und das Verbindungselement elektrisch isolierend ist, kann eine Kühlflüssigkeit entlang einer gesamten Länge der flüssigkeitsgekühlten Busbaranordnung durch den Kühlkanal geleitet werden, wobei ein gleichzeitiger elektrischer Stromfluss auf eine oder mehrere Teilabschnitte der flüssigkeitsgekühlten Busbaranordnung begrenzbar ist.Because the first, the second and the third continuous cavity form a coherent cooling channel and the connecting element is electrically insulating, a cooling liquid can be conducted along an entire length of the liquid-cooled busbar arrangement through the cooling channel, with a simultaneous flow of electrical current to one or more sections the liquid-cooled busbar arrangement can be limited.
Bevorzugt ist die erfindungsgemäße flüssigkeitsgekühlte Busbaranordnung für den Einsatz in Traktionsbatterien vorgesehen.The liquid-cooled busbar arrangement according to the invention is preferably provided for use in traction batteries.
Vorzugsweise umfasst das Verbindungselement der erfindungsgemäßen flüssigkeitsgekühlte Busbaranordnung eine erste Vertiefung, welche dazu ausgebildet ist, auf ein Ende des ersten leitfähigen Körpers aufgesteckt zu werden, und eine zweite Vertiefung, welche dazu ausgebildet ist, auf ein Ende des zweiten leitfähigen Körpers aufgesteckt zu werden.The connecting element of the liquid-cooled busbar arrangement according to the invention preferably comprises a first recess, which is designed to be plugged onto one end of the first conductive body, and a second recess, which is designed to be plugged onto one end of the second conductive body.
Die Vertiefungen im Verbindungselement ermöglichen einen einfachen Aufbau der erfindungsgemäßen flüssigkeitsgekühlten Busbaranordnung durch Zusammenstecken von Einzelteilen.The recesses in the connecting element allow a simple construction of the liquid-cooled busbar arrangement according to the invention by plugging together individual parts.
Besonders bevorzugt ist der Aufbau modular und mit weiteren Verbindungselementen und leitfähigen Körpern erweiterbar.The structure is particularly preferably modular and can be expanded with further connecting elements and conductive bodies.

- a) a liquid-cooled busbar arrangement according to the invention
- b) a first battery cell which is mechanically, electrically and thermally connected to the first formation of the first conductive body and
- c) a second battery cell which is mechanically, electrically and thermally connected to the second formation of the first conductive body,
wherein the first battery cell and the second battery cell are electrically connected in series with each other via the first conductive body.
Dadurch, dass die erste und zweite Batteriezelle mechanisch, elektrisch und thermisch an Ausformung des ersten leitfähigen Körpers angebunden sind, können die Zellen des erfindungsgemäßen Batteriemoduls bei Auf- und Entladevorgängen über Stromführende Zellanschlüsse gekühlt werden.Because the first and second battery cells are mechanically, electrically and thermally connected to the formation of the first conductive body, the cells of the battery module according to the invention can be cooled via current-carrying cell connections during charging and discharging processes.
