A battery system for an electric vehicle includes: a plurality of battery cells, each of the battery cells including electrode terminals; a busbar interconnecting the battery cells by contacting the electrode terminals; a battery housing enclosing the battery cells; and an electrically and thermally insulating cover element. The cover element covers the electrode terminals and the busbar such that the electrode terminals and the busbar are shielded from venting products exiting one or more of the battery cells towards the battery housing during a thermal runaway.

Battery system and vehicle including the battery system

A battery system includes: a plurality of battery cells, each of the battery cells having a venting side including a venting exit configured to allow venting products to exit the battery cells during a thermal runaway and a cooling side opposite the venting side; a cooling plate, the cooling side of the battery cells being in thermal connection with a first side of the cooling plate; and a battery housing enclosing the battery cells in a cell chamber. A guiding channel is formed between a second side of the cooling plate opposite the first side and a channel wall of the battery housing facing the second side of the cooling plate, and a passage fluidly connects the cell chamber and the guiding channel. Thus, when the venting products are emitted by the battery cells from the venting side into the cell chamber, the venting products are directed along a venting path from the cell chamber through the passage into the guiding channel and through the guiding channel to an environment of the battery system via a system exit.

A battery system includes: a plurality of battery units, each of the battery units including at least one battery cell, the at least one battery cell including a positive terminal, a negative terminal, and a cell case; and a flexible printed circuit (FPC) including a plurality of integrated circuits (ICs) configured for voltage measurement and temperature measurement. The ICs are interconnected by a wiring structure of the FPC. Each of the ICs is thermally connected to the cell case of the at least one of battery cell of each of the battery units via a contact element in the FPC and is electrically connected via the contact element to the positive terminal of the at least one battery cell of each of the battery units.

Battery system with a flexible printed circuit

A battery system for an electric vehicle includes a high voltage battery including a plurality of battery cells interconnected with one another configured to provide a high voltage output at battery system terminals and a battery disconnecting element powered by the high voltage battery and configured to disconnect the high voltage battery from at least one of the battery system terminals in the event of a malfunction or crash.

A pyro igniter circuit and a method for testing the same is provided. The pyro igniter circuit includes a supervisory circuit configured to: transmit a test signal having a pulse duration time below an igniter activation pulse time of a pyro igniter disconnect element and/or an ignition control signal, in response to the transmitted test signal, has an amplitude below an igniter activation amplitude of the pyro igniter disconnect element; and receive a diagnostic response signal in response to the transmitted test signal.
