Problems solved by technology

[0005] However, today's available electric energy storage systems, especially battery pack systems, cannot increase the voltage during charging, because their wiring (for example in series or in parallel) is fixedly wired, and at the same time it is not possible to connect the Existing components, such as inverters, continue to operate at the operating voltage level

Embodiment Construction

[0028] In all figures, the same reference numerals refer to the same device components or method steps.

[0029] figure 2 A circuit arrangement 200 according to the invention for a vehicle with two electric energy storage units R1 and R2 according to a first embodiment is shown. In this case, electrical components are depicted in the area on the left, which can remain unchanged when using the circuit arrangement 200 according to the invention. In particular, the electrical components are an electric motor 107 , an inverter 106 , a DC / DC converter 104 for a 12 V vehicle electrical system and a vehicle electrical system battery pack 105 , an intermediate circuit with an intermediate circuit capacitor 103 and an air-conditioning compressor 102 . All electrical components connected to the circuit arrangement 200 via the first output A1 and the second output A2 can therefore continue to be used unchanged. The electrical energy storage cells R1 and R2 are connected within the bat...

Abstract

The invention provides a circuit device used for an electric energy storage system with at least two electric energy storage units equipped with first electrodes and second electrodes. The circuit device comprises at least one first input end and second input end electrically connected with an energy source; at least one first output end and second output end electrically connected with electric components; at least two first electrode wiring terminals and second electrode wiring terminals; at least two first switches; at least two second switches and at least one third switch. The first output ends are electrically connected with second wiring terminals of the first switches; the second output ends are electrically connected with second wiring terminals of the second switches; the first switches, the second switches, the third switches and other switches are switched to make the electric energy storage units connected in series or in parallel in order to charge at least one of the electric energy storage units by using the energy source connected to the first input ends and the second input ends during charging operation of the circuit device and / or in order to operate the electric components connected to the first output ends and the second output ends during discharge operation of the circuit device.

Description

technical field [0001] The invention proceeds from a circuit arrangement and an operating method for an electrical energy storage system according to the preambles of the independent patent claims. Background technique [0002] In today's electrically driven vehicles, especially electric vehicles (EV) or hybrid electric vehicles (HEV), battery modules are constructed by connecting individual battery cells in parallel and in series, said battery modules functioning outwardly in the vehicle. The role of the battery pack. The battery pack has a rated voltage that defines a voltage range for charging and discharging processes according to the state of charge and load of the battery pack. [0003] Today, the charging of electrically driven vehicles, especially vehicles having a battery pack as the main energy source, is the subject of intensive research and development. On the one hand, this is because: the current charging time for a complete battery pack is still very long, a...
