More readily available traction battery

Abstract

The invention relates to a traction battery comprising at least two serially connected battery modules (1, 2), each of which has a first battery module pole (1a, 2a), a second battery module pole (1b, 2b), and at least one inserted series circuit and / or parallel circuit of battery cells (1c, 2c). A first terminal (3) of the series circuit of battery modules (1, 2) is connected to a first battery pole (4), while a second terminal (5) of the series circuit of battery modules (1, 2) is connected to a second battery pole (6). According to the invention, at least one battery module (1) of the at least two serially connected battery modules (1, 2) is a first battery module (1) which has a first disconnecting device (1d), a second disconnecting device (1f), and a bridging device (1e). When triggered accordingly, the first disconnecting device (1d) interrupts the connection between the series circuit and / or parallel circuit of battery cells (1c) and the first battery module pole (1a), and when triggered accordingly, the second disconnecting device (1d) interrupts the connection between the series circuit and / or parallel circuit of battery cells (1c) and the second battery module pole (1b). Furthermore, the first battery module pole (1a) and the second battery module pole (1b) are short-circuited via the bridging device (1b) inserted between the first battery module pole (1a) and the second battery module pole (1b) when the bridging device (1b) is triggered accordingly. Additionally or alternatively, at least one battery module (2) of the at least two serially connected battery modules (1, 2) is a second battery module (2) that has at least one charging and disconnecting device (2d), a disconnecting device (2f), and a bridging device (2e).

Description

technical field [0001] The invention relates to a battery, in particular a traction battery, according to the preamble of claim 1 . Background technique [0002] It has emerged that in the future new battery systems will be increasingly used not only in stationary applications (e.g. wind power plants) but also in vehicles (e.g. in hybrid and electric vehicles), for which new battery The system puts forward very high requirements or reliability. The background to these high demands is that the failure of the battery can lead to the failure of the entire system (for example, in electric vehicles, the failure of the traction battery leads to the so-called battery, so that during strong winds the rotor blades are regulated to avoid unreliable operation of the device). [0003] Furthermore, there are often requirements for battery systems in stationary applications that it must also be possible to operate the battery system during maintenance work, if required with a limited op...
