NOVELTY - A battery configuration comprises: a set of battery cells; a battery case defining a space and housing the battery cells; and a thermally-conductive electrically-insulating liquid flooding the space and coating the battery cells for conducting heat away from the battery cells while maintaining electrical integrity.    USE - The battery configurations are useful for regulating temperature in a multiple-cell battery and for use in vehicles (all claimed).    ADVANTAGE - The battery configuration is simple, cost-effective, efficient and wear resistant.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are:    (1) a temperature-controlled battery configuration, comprising: the set of battery cells, with conductive electrodes for accessing electrical power capacity of the cells; a system of interconnecting hardware that allows multiple cells to function together as an electrical storage battery; a control system including circuitry that is electrically connected to the cells for at least one of monitoring or controlling the battery configuration; a container sized and shaped to contain and encapsulate the cells along with the system of interconnecting hardware and at least a portion of the control system; and an electrically-insulating heat-transfer liquid filling the container and having direct contact to the cells, the hardware, and the portion of the control system in the container;    (2) a vehicle comprising: a vehicle body with wheels and seating that is adapted to carry passengers and/or cargo; an electric battery-powered motor for powering the vehicle; the temperature-controlled battery configuration comprising the battery including the casing with an inlet and an outlet, and an alternating arrangement of lithium-ion cell packs and spacers with at least one spacer between each of the cell packs, the spacers supporting at least part of a weight of the cell packs in the casing, the spacers further defining with adjacent ones of the cell packs a set of channels; a thermally-conductive electrically-insulating fluid for passing into the inlet, along the channels and against an outer surface of the cell packs, and to the outlet for controlling a temperature of the cell packs; a fluid pump for pumping the fluid; a heat exchanger for controlling a temperature of the fluid; fluid lines operably connecting the pump, the inlet, the outlet and the heat exchanger; the lines being filled with the thermally-conductive fluid; and a controller for controlling the pump and flow of the fluid to control a temperature of the battery configuration to maintain a desired temperature range of the cell packs; and    (3) a method of regulating temperature in a multiple-cell battery comprising: providing a battery with multiple cells spaced apart by spacers, at least a part of a weight of the cells being supported by the spacers and a combination of the cells with adjacent ones of the spacers forming fluid-conducting channels; providing an electrically-insulating heat-transfer fluid; passing the fluid through the channels past an outer surface of each of the cells under adjacent ones of the spacers at a rate sufficient to regulate cell temperature, including deliberately and directly impinging the fluid against the outer surfaces of the cells, but with the fluid not significantly interacting with the cell's electrical charge nor detrimentally affecting the cell's materials of construction; and controlling a temperature of the fluid to achieve temperature control of the cells.
