Temperature Adjusting Device And Method Used For Battery Cell And Battery Module, Battery Unit, Battery And Battery System

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...

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
