    摘要： An energy store has a plurality of electrical energy storage cells, which are connected electrically in series or parallel and are combined to form an energy storage module. Cooling plates are arranged between the energy storage cells and into which coolant or refrigerant can be introduced. Each cooling plate has a support frame, which extends around an elastic insert. The elastic insert forms a channel structure, which guides the coolant or refrigerant through the elastic insert. A method for producing the energy store has the following steps: adhesively bonding a first electrically insulating film to a side of a support frame of a cooling plate; arranging an elastic insert within the support frame, whereby the elastic insert is also adhesively bonded to the first electrically insulating film, and alternately stacking energy storage cells and cooling plates to form an energy storage module.

    摘要： A cell system includes: a stacked-type cell module (100) having a plurality of lithium ion unit cells (1) being stacked and having through holes (3a, 3b) formed therein; a gas supply part (31); a cooling liquid supply part (32); a temperature sensor (35); and a control part (36) that controls switching between a normal control mode and a high-temperature control mode based on a signal from the temperature sensor (35). In the normal control mode, the control part (36) controls the gas supply part (31) to supply a gas to the through holes (3a, 3b), and at the same time, controls the cooling liquid supply part (32) to stop supply of a cooling liquid, and in the high-temperature control mode, the control part (36) controls the cooling liquid supply part (32) to supply the cooling liquid to the through holes (3a, 3b) to which the gas is supplied, and at the same time, controls the gas supply part (31) to stop supply of the gas. According to this cell system, the increase in temperature of the cell is suppressed while having a simple configuration with a reduced formation region of through holes provided in a lithium ion cell.

    摘要： Thermal management systems for battery cells and methods for their additive manufacture are provided. The thermal management systems include at least one heat pipe that physically contacts the battery cell and conforms to its geometry. Each battery cell is deposited within a separate heat pipe, and each heat pipe is disposed on a base plate, which itself connects to a heat sink. In many embodiments, the heat pipe is a two-phase heat exchanger having three major components: liquid channels, wick elements, and vapor channels. In such embodiments, the wick component comprises a porous body configured to be disposed between the liquid channels and vapor channels. The wick component may be made using a stochastic additive manufacturing process such that the wick component may take any configuration and/or such that the wick component may be directly integrated into the body of the heat pipe as a unitary piece thereof. In other embodiments, the heat pipe is a cavity with flow channels in which fluid can be pumped through. In some such embodiments, the fluid can occupy the heat pipe in a one-phase or two-phase state. This unitary heat pipe is part of a monolithic thermal management system.
