Problems solved by technology

This increases the price as well as the weight and bulk of the battery system which is a problem especially for electric vehicles
[0005] 2. Since the voltage of each battery cell added by series connection, the assembly of the battery, that is, the connection of each battery cell is carried out at a high voltage up to 1000V, so it is not possible to carry out the battery, each battery cell or module in the local factory. replacement, or in stationary applications only by specially trained specialists with special tools
This results in a high logistical outlay for maintaining the battery system in the event of a failure
[0006] 3. In order to switch the battery system voltage-free, that is to say to separate the actual battery from the load, power switches 11-1 and 11-2 must be connected upstream, which are typically implemented as contactors and for the expected high currents and high expensive for voltage

Embodiment Construction

[0023] figure 2 A first embodiment of the present invention is shown. In the example three DC / DC converters 21-1, 21-2 and 21-3 are seen, but in real applications the number of DC / DC converters could be significantly higher. Each of the DC / DC converters 21-1, 21-2, and 21-3 is connected on the input side with one battery module 20-1, 20-2, 20-3, and these battery modules 20-1, 20-2 , 20 - 3 each have a plurality of battery cells connected in series in the example. as in figure 2 As can be seen in , according to the present invention, the output ends of the DC / DC converters 21-1, 21-2, 21-3 are connected in series, thereby serving as the The sum of the individual voltages produced yields the total voltage between the output terminals 22-1 and 22-2 of the device. The DC / DC converters 21-1, 21-2, 21-3 are constructed in a known manner and allow adjustment of the first and second The output voltage applied at the output either switches off the DC / DC converter 21 - 1 , 21 - 2 ...

Abstract

An energy transmission device for a battery system, a battery system with such an energy transmission device, and a motor vehicle with such a battery system. The energy transmission device comprises a plurality of DC / DC converters, these DC / DC converters respectively have a first input terminal and a second input terminal and a first output terminal and a second output terminal, wherein the first input terminal And the second input is designed for connecting a battery module, wherein the DC / DC converters are connected in series on the output side.

Description

Background technique [0001] There is an increasing demand for battery systems used in stationary applications such as wind power plants and backup power systems, or in vehicles. All these requirements place high demands on reliability and fail-safety. The reason for this is that a complete failure of the voltage supply via the battery system can lead to failure of the entire system. Batteries are used in wind energy installations to adjust the rotor blades in strong winds and to protect the installation from excessive mechanical loads that could damage or even destroy the wind energy installation. In the event that the battery of the electric vehicle fails, the driving performance is poor. The backup power system should in turn ensure uninterrupted operation of eg a hospital and therefore cannot fail. [0002] In order to be able to provide the power and energy required for the respective application, the individual battery cells are connected in series and in some cases ad...
