Abstract:
The present invention is concerned with a cooling process for electrical or electrochemical charge storage devices. According to the invention, a charge storage device with a vertical arrangement and fluidal interconnection of modules is proposed that allows for the distribution, evaporation and recycling of a coolant based on a single two-phase fluid cooling circuit. The device is adapted for an equal distribution of cooling fluid throughout the modules of the arrangement to support an equal temperature distribution by means of immersed two-phase dielectric liquid cooling. The latter provides the same temperature of cooling fluid for all cells in the device as long as the fluid remains in the saturated state at the same pressure.
Abstract:
The present invention of operating a first battery system (10), wherein the first battery system (10) is part of a plurality of interconnected battery systems (10, 12, 14, 16), wherein - at least the first battery system (10) of the plurality of battery systems (10, 12, 14, 16) is positioned in a first electrically driven vehicle of public transport and at least a second battery system (12, 14, 16) of the plurality of battery systems (10, 12, 14, 16) is positioned in a second electrically driven vehicle of public transport, wherein - at least the first battery system (10) is connected to at least the second battery system (12, 14, 16) via a data connection (11), wherein - the first battery system (10) is operated based at least on operating information of the first battery system (10) and of the second battery system (12, 14, 16), and wherein - the operating information of the first battery system (10) comprise at least one of location information, driving information, and status information of the first battery system (10) and wherein the operating information of the second battery system (12, 14, 16) comprise at least one of location information, driving information, and status information of the second battery system (12, 14, 16). Such a method provides an improved reliability of a system of public transport.
