Problems solved by technology

When the traction power is, for example, 60KW, there will be a loss of 5%, that is, a power loss of 3KW
Furthermore, for example in the summer months or in hotter regions, outside temperatures of 40°C or higher are outside the permissible temperature range, so that the battery cells cannot reach, for example, 10 or more years without cooling. 15 years of life

Embodiment Construction

[0052] figure 1 Shown is a schematic perspective view of a battery module 10 according to one embodiment of the invention.

[0053] The battery module 10 includes a plurality of battery cells 100, namely 100 1 ...100 3 , such as two, three, four or more battery cells. Such as figure 1 Shown exemplarily in , the battery cell 100, 100 1 ...100 3 They are oriented in a first spatial direction, so that their longitudinal sides run parallel to one another, which are oriented in a second spatial direction perpendicular to the first spatial direction. In the case of intended use, a third spatial direction perpendicular to the first spatial direction and the second spatial direction is referred to as a battery cell 100 , 100 1 ...100 3 height direction.

[0054] Accordingly, a battery pack, battery or battery system may include a plurality of battery modules.

[0055] Battery cell 100, 100 1 ...100 3 Can be prismatic, such as square, and include a single cell housing 110 re...

Abstract

The invention provides a temperature adjusting device (30, 40, 50, 60, 70, 80, 90, 200, 220, 300, 310, 320, 330) used for battery cells (100). The device is characterized in that a pipe or a hose (300) includes a channel used for accomodating the temperature adjusting agent; a plurality of connection mechanisms (200) used for accomodating the channels (210) of the pipe or the hose, wherein the connection mechansims can be disposed appropriately so as to enable the pipe or the hose (300) to be disposed in the channels (210) of the connnection mechanisms (200) and the temperature adjusting agent can be used for temperature adjustment of the battery cell (100). The invention also discloses the battery modules (10, 20), a battery unit, a battery, a battery system, a vehicle and a method for performing temperature adjustment of the battery cell (1001...1003).

Description

Background technique [0001] Lithium-ion batteries consist of a positive electrode (anode) and a negative electrode (cathode) which are reversibly loaded (inserted) with lithium ions (Li+) during charging or unloaded (removed) with lithium ions during discharge. In this case, the volume of the lithium-ion accumulator increases during charging due to the insertion and decreases during discharging due to the removal. Lithium-ion batteries have high energy density and low self-discharge. [0002] However, it is foreseeable that as rechargeable electric accumulators ( EES), newer battery systems such as lithium-ion accumulators or nickel-metal hybrid accumulators are increasingly used. [0003] Such battery systems have to meet high requirements with regard to usable energy content, charging / discharging efficiency, reliability, lifetime and undesired loss of capacity due to frequent partial discharges. [0004] The battery system includes a plurality of battery cells. Battery c...
