Abstract: A method of assembling and electrically interconnecting an energy storage system, the system includes a cabinet and a plurality of energy storage modules which may be connected together in the cabinet, each energy storage module has a plurality of energy storage devices. The method includes carrying out an electrical interconnection step by providing a removable current monitoring device at one pole of a circuit of the cabinet during the electrical interconnection step; connecting a first module to the pole; monitoring current flow after connecting the first module and, if no current flow is detected, connecting a further module in series with the first module. The monitoring and connecting steps are repeated for each subsequent module until all modules of the cabinet have been electrically interconnected. The final module is connected to the other pole of the circuit and the current monitoring device is disconnected and removed from the circuit.

Abstract: Additional cooling is provided to an energy storage module of a cooling system with a plurality of cooling channels in contact with a surface of an energy storage device, by pipe connections of a common cooling fluid outlet pipe that have a lower melting point than pipe connections of the common cooling fluid inlet pipe. In use, if the pipe connections are subjected to elevated temperatures, or fire, the pipe connections of the common fluid outlet pipe fail before the pipe connections of the common fluid inlet pipe, causing a pressure drop, whereby the rate of fluid flow through the cooler of the energy storage module in which the pipe connection has failed is substantially increased.

Abstract: An exhaust system for energy storage modules connected in series in a cubicle and energy storage cubicles connected in parallel. A cubicle exhaust duct is connected to each of the storage modules in one cubicle and an opening between each of the storage modules and the exhaust duct. A common exhaust duct is connected to each cubicle exhaust duct, an extractor fan, a fluid inlet for the extractor fan with a duct connected to a source of air and a fluid outlet for the extractor fan. A cross section of the fluid inlet is smaller than the fluid outlet. An entry of the fluid inlet and an exit of the fluid outlet are outside the storage device and outside a compartment of the storage device. The extractor fan circulates air and creates an under-pressure in the common exhaust duct and cubicle exhaust ducts to guide gas out the exhaust ducts.

Abstract: An energy storage module with one or more energy storage devices and a cooler on which the energy storage device is mounted in contact with the energy storage device. The cooler has one or more cooling fluid channels for circulating cooling fluid, the channels being in contact with a surface of the energy storage device, each cooling fluid channel being adapted to receive cooling fluid from a source of cooling fluid, extract heat from the energy storage device and return the cooling fluid to the source. At least a part of the cooling fluid channel includes a material having a melting point above 100° C.

Abstract: A mounting system for an energy storage module having a plurality of energy storage devices electrically connected together in series. Each energy storage module further includes a plurality of coolers onto each one of which one of the plurality of energy storage devices is mounted. The mounting system has two or more connectors on each cooler, each connector with a first part and a second part. Each connector is connectable with a corresponding second part and first part on another cooler. Each first part includes a resilient member supporting a protruding tab and each second part includes a corresponding slot to receive the protruding tab. The mounting system further includes an electronics board mount, the mount having one or more pairs of resilient locating members spaced from one another by a distance substantially equal to a width of the electronics board. Each resilient locating member includes a downward facing surface.
