An electrochemical energy accumulator (100) and a method for balancing a multiplicity of sections (S1, S2, S3) of electrochemical accumulator modules (10) connected in parallel with one another by means of at least one UniBB module are proposed. In this context, the following steps are carried out: detecting (S100) a first state of charge (I) of a first accumulator module (M1), detecting (S200) a second state of charge (II) of a second accumulator module (M2), wherein the second accumulator module (M2) is a UniBB module, and operating (S300) the second accumulator module (M2) as a power source in order to adapt the first stage of charge (I) and the second state of charge (II) to one another. |
