Abstract

The invention discloses a battery module (221). The battery module (221) has a battery cell circuitry (226) that is provided with several battery cells (21), and a monitoring and control unit (230) which is used for monitoring the functional state of the battery module (221). The battery module (221) comprises a couple unit and a discharge circuit (270). The couple unit is connected with power semiconductors (241,242) in half bridge arrangement, for coupling the battery cell circuitry (226) to output terminals (224,225). The discharge circuit (270) is coupled with the battery cell circuitry, for enabling the fast discharge of the battery module. The couple unit and the discharge circuit are controlled by the monitoring and control unit (230).

Description

technical field [0001] The invention relates to a battery module having a battery cell circuit with a plurality of battery cells and a monitoring and control unit for monitoring the functional state of the battery module. The invention also relates to a method for monitoring a battery module by means of monitoring and control cells arranged in the battery module. Furthermore, the invention relates to a battery system comprising a battery and a battery management system, the battery having at least one battery pack in which a plurality of battery modules are accommodated. Background technique [0002] Batteries used in hybrid and electric vehicles are generally referred to as traction batteries, since they are used to power the electric drive. In order to achieve the power and energy quantities required in hybrid and electric vehicles, the individual battery cells are connected in series and some additionally in parallel. In electric vehicles, ten or more cells are often co...
