Battery temperature control device for charging and replacing power station, and electric vehicle charging and replacing power station

Abstract

The invention relates to a battery temperature control device for a charging and replacing power station, and an electric vehicle charging and replacing power station. The battery temperature controldevice comprises: a pipeline portion, a liquid cooling machine unit and a control portion, wherein the pipeline portion is connected to one or more batteries of the charging and replacing power station and is used for providing a refrigerant for the batteries to heat or cool the batteries; the liquid cooling machine unit is connected with the pipeline portion and is used for cooling or heating therefrigerant provided for the pipeline portion; and the control portion is connected with the liquid cooling machine unit and is used for controlling the liquid cooling machine unit and the pipeline portion. The charging and replacing power station comprises one or more battery temperature control devices, and the battery temperature control device is arranged in a battery compartment in the electric vehicle charging and replacing station. The pipeline portion, the liquid cooling machine unit and the control portion all adopt a split design, the length of a cable or a hose can be adjusted according to specific space layout requirements, the installation positions of the pipeline portion, the liquid cooling machine unit and the control portion are set, and the requirements of internal design and layout diversity of the charging and replacing power station are met.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery temperature control device for a charging and swapping station and an electric vehicle charging and swapping station. Background technique [0002] With the rapid development of electric vehicles, how to quickly realize the energy supply of electric vehicles and make electric vehicles as convenient as traditional fuel vehicles is one of the important problems faced by the electric vehicle industry. The emergence of charging and swapping stations has successfully solved this problem . The charging and swapping station replaces the battery on the car that needs to be replenished with a fully charged battery in the battery compartment, and sends the replaced battery into the battery compartment for charging. Lithium-ion batteries are the core components of electric vehicles. As users' requirements for electric vehicles increase, the requirements for the power ...

AI Technical Summary

Problems solved by technology

[0004] (1) The display screen of the existing water-cooling system is placed on the unit of the water-cooling system, and the equipment that blocks the display screen cannot be placed in front of the control screen, which limits the flexibility of the design and layout of the charging and swapping station

[0005] (2) Circuit breakers, relays and other components are usually installed inside the water-cooled unit. When the water-cooled unit fails and needs to be powered off in time, or manually restored, it will affect the normal operation of other equipment in the charging station

[0008] B: After the water-cooling system is filled to a certain level, the operation of the water-cooling system is manually resumed, which increases the operating burden and causes the water-cooling system to not recover in time

[0009] To sum up, some components on the control part and pipeline part of the existing charging and swapping station water cooling system are placed in the water cooling unit or near the water cooling unit, and the location of each component cannot be adjusted according to the specific layout requirements, so that the charging and replacing Electrical layout has limitations
