Battery system and method for the homogeneous temperature distribution inside the battery system

A method for a homogeneous temperature distribution inside a battery system, the battery system including a battery housing, a battery cell holder including a plurality of battery cells which is situated inside the battery housing, and a battery management system which is configured to monitor the plurality of battery cells and detect temperatures of the individual battery cells of the plurality of battery cells, the method comprising:

• activating, by the battery management system and as a function of at least one of the temperatures of the individual battery cells exceeding a threshold value, a blower that is situated inside the battery housing on the battery cell holder;
• wherein:
• the battery housing includes a base body, a first cover element closing a first open end face of the base body, and a second cover element closing a second open end face of the base body;
• the battery housing includes an airflow area beneath the battery cell holder;
• the battery cell holder includes a first passage that, between at least two of the battery cells, extends from airflow area to the blower;
• and
• the activating of the blower causes the blower to blow air, which flows from in the airflow area to the blower via the passage, into a second passage that is above the battery cell holder.

An electrically operated two-wheeler, comprising:

• a battery system including:
• a battery housing, which includes a base body, a first cover element, and a second cover element, the first cover element closing a first open end face of the base body, and the second cover element closing a second open end face of the base body;
• a battery cell holder which includes a plurality of battery cells, the battery cell holder being situated inside the battery housing;
• a battery management system configured to monitor the plurality of battery cells and detect temperatures of individual battery cells of the battery cells;
• a blower situated inside the battery housing on the battery cell holder;
• wherein:
• the blower is activated by the battery management system as a function of the temperatures of the individual battery cells exceeding a threshold value;
• the battery housing includes an airflow area beneath the battery cell holder;
• the battery cell holder includes a first passage that, between at least two of the battery cells, extends from airflow area to the blower;
• and
• the blower is configured to blow air, which flows from in the airflow area to the blower via the passage, into a second passage that is above the battery cell holder.
