1. A modular system for forming control units for traction batteries of motor vehicles, the modular system comprising:
plural first modules (A, B) and plural second modules (D, E, H),
each of the plural first modules (A, B) being configured to:
(a) determine a state of charge from cell voltages of several battery cells of one of the traction batteries;
(b) control a discharge of the battery cells;
(c) exchange data with at least one other component of the respective motor vehicle; and/or
(d) establish and interrupt an electrical connection between the respective traction battery and the at least one other component of the respective motor vehicle,
each of the plural second modules (D, E, H) being different from each of the plural first modules (A, B),
the modular system being configured to define:
plural first control units (1) for first traction batteries of first motor vehicles, each of the first control units (1) comprising one of the first modules (A, B) and one of the second modules (D, E, H); and
plural second control units (2, 3) for second traction batteries of second motor vehicles, each of the second control units (2, 3) comprising one of the first modules (A, B) and none of the second modules (D, E, H).
