Embodiment Construction

[0023] figure 1 The circuit diagram of a hybrid vehicle battery 1 shown in shows its important components. A hybrid vehicle battery 1 includes a plurality of cells 2 connected in series. Multiple cells 2 form a cell module 3 . exist figure 1 In the embodiment shown in , each cell module comprises two cells 2 . However, embodiments are also conceivable in which each monomeric template 3 comprises, for example, three, four or five monomers.

[0024] Each cell module 3 is assigned a control device 4 for cell monitoring and cell balancing. The cell balancing ensures that the individual cells 2 of a cell module 3 are discharged at least approximately uniformly, so that their service life is extended.

[0025] The individual control devices 4 are connected to a higher-level battery management controller 5 which has a communication interface 6 for exchanging information with external controllers of the vehicle. Furthermore, the battery management controller 5 can be switched of...

Abstract

The invention relates to an HV-battery, in particular a traction battery for a vehicle, having a plurality of cell modules which each comprise a plurality of cells, wherein each cell module is assigned a controller for cell monitoring and / or for cell balancing, wherein the controllers are connected to a battery management control device for communication or control and / or regulation purposes, wherein the HV-battery is of modular construction, in that the cell modules are constructed as plug-in modules that are or can be detachably fixed to a board.

Description

technical field [0001] The invention relates to a battery of a hybrid electric vehicle, especially a power battery of a vehicle, which has a plurality of monomer (single battery) modules, and the monomer modules respectively include a plurality of monomers, wherein each monomer module is equipped with a useful A control device for cell monitoring and / or for cell balancing, wherein the control device is connected to the battery management controller for communication purposes and / or control or regulation purposes. Background technique [0002] Hybrid vehicle batteries (high-voltage batteries) are used, for example, as traction batteries for hybrid vehicles. Metal hydride batteries / metal hybrid batteries (Metall hybrid batteries) or lithium-ion batteries are used as batteries. Several individual cells of the battery are connected in series, whereby the voltage required by the electric motor is generated. [0003] A modular traction battery is known from EP1577966A2, which ha...
