Problems solved by technology

Disadvantages pertaining to fast charging of batteries are: for example, although lithium-ion batteries offer a relatively high power density, they are also prone to overcharging, deep discharging and high charging currents, which can lead to rapid charging of high-voltage batteries, especially at high ambient temperatures. overheat
[0017] A disadvantage of systems with external cooling capacity is that a very high infrastructure outlay is required in order to additionally provide a cooling station at the charging station
[0018] Furthermore, the coupling of the charging station and the cooling system of the vehicle for the charging process involves additional operational effort for the user
In addition to the electrical connection, the additional coupling of the system by establishing the fluid connection can also be technically more complex to secure than the electrical connection for the charging process of the battery

Embodiment Construction

[0073] in figure 1 An air conditioning and battery cooling device 1 with two coolers 12 and 14 is shown as a circuit diagram with all important components and optional wiring. In addition to refrigeration facilities, the total thermal system composed of a combination of coolant and refrigerant circulation circuits also has a heat pump function. This can be understood as the use of air conditioning and battery cooling devices to provide cold and heat to the vehicle.

[0074] The system is composed of two coolant circulation circuits and one refrigerant circulation circuit, wherein the coolant circulation circuits can be coupled to each other.

[0075] The A / C coolant circulation loop is shown as a thin double line.

[0076] The refrigerant circulation circuit is shown as a double line with a medium line width. The electric drive train coolant circulation loop including the battery cooling loop is shown in thick double lines.

[0077] In circuits with different operating states, the l...

Abstract

An air conditioning and battery cooling assembly with an A / C coolant circuit and an E-drive train coolant circuit as well as a refrigerant circuit, wherein the A / C coolant circuit and the E-drive train coolant circuit are coupled together across a 4 / 2-way coolant valve in such a way that the A / C coolant circuit and the E-drive train coolant circuit can be operated separately or can receive a flowin serial manner.

Description

Technical field [0001] The present invention relates to an air conditioning and battery cooling device with high cooling power and passive battery cooling for battery electric vehicles, and a method for air conditioning and battery cooling of the vehicle. Background technique [0002] The invention particularly relates to the design of thermal systems for electric vehicles, vehicles with hybrid drives, or fuel cell vehicles operated by so-called high-voltage batteries or accumulators. The above-mentioned highly electrified vehicles are usually equipped with the possibility of fast charging for electric energy storage. Associated with this is the increased demand for cooling of the corresponding energy storage during rapid charging. In addition, a large charging current leads to high electrical losses and therefore to strong heating of the energy storage. [0003] Therefore, during the rapid charging of the battery, the thermal system must provide a particularly high cooling power...
