Battery test bench and system for testing batteries

A battery test bench (100) for testing batteries (200, 201), comprising:

• a test cell (110);
• at least two electric power sources (120, 121);
• and
• at least four current rails (130, 131, 132, 133), and
• at least one rail bridge (150, 155) configured to connect a battery (200, 201) simultaneously to the at least two electric power sources (120, 121), so that the at least two electric power sources (120, 121) are connected in parallel:
• wherein the at least two electric power sources (120, 121) are each configured to supply an electric voltage and to deliver an electric current, and
• wherein the at least four current rails (130, 131, 132, 133) are configured for the electrical connection of the at least two electric power sources (120, 121) each to a respective battery (200, 201) to be tested,
• wherein the test cell (110) is configured to accommodate and arrange the at least four current rails (130, 131, 132, 133).
