Abstract
Abstract High-temperature battery with at least one electrochemical storage cell which is surrounded by thermal insulation as well as by feed and discharge lines for the cooling air. At least one module which can be inserted into the high-temperature battery, contains the storage cells. The module has a feedline for cooling air and a discharge for the cooling air which are arranged so that the cooling air can be introduced into the module against the force of gravity and discharged from the module with the force of gravity.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
245 words
High-temperature battery comprising a thermal insulation housing for enclosing electrochemical storage cells, at least one housing air inlet for feeding cooling air into the interior of the housing, and at least one housing air outlet for the discharge of said air from the housing, at least one module containing electrochemical storage cells for insertion into the interior of said housing, said module having at least one feedline for the flow of cooling air in the housing into said module against the force of gravity and at least one discharge passage, through which the air leaves said module with the force of gravity, said feedline arranged at a first lateral end and the discharge passage arranged at a second other lateral end of the module, said feedline and said discharge passage have an inlet opening and an outlet opening respectively, in the lower region of the lateral ends of the module, said feedline and said discharge passage are in connection with the interior of the module containing the storage cells only via a respective connecting opening in the upper region of the module, said storage cells in the module arranged to provide empty spaces between them for the cooling air conducted in the interior of the module to flow through these spaces along the length of each storage cell, and empty spaces as passageways between the storage cells and the inner boundary surface of the module are provided for passage of cooling air in the module.
