Problems solved by technology

The heated cooling water will produce a large amount of heat loss in the long-distance pipelines, so a large-power cooling water heating device is usually required, which not only leads to a larger volume of the cooling water heating device, but also has low heating efficiency, not only It wastes the power of the battery box and affects the cruising range of the electric vehicle

Abstract

The invention discloses a water chamber device, a car with the water chamber device and a method for heating and cooling a car battery. The water chamber device comprises a water chamber body, a cooling water heater, a water outlet switching device and a controller, a hollow cavity allowing cooling water to flow is formed in the water chamber body, and the water chamber body is provided with a water inlet allowing the cooling water to flow in and a water outlet allowing the cooling water to flow out; the cooling water heater is arranged in the water chamber body to heat the cooling water in the hollow cavity; the water outlet switching device is used for opening or closing the water outlet; the controller is used for starting or stopping the cooling water heater and controlling the water outlet switching device to close or open the water outlet according to the starting or stopping state of the cooling water heater and the temperature of the cooling water. The volume of the cooling water needing to be heated is reduced, and the cooling water heater is arranged in the water chamber device, so that heat losses in a pipeline are avoided, the heating efficiency is improved, and the heating speed is increased.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a water chamber device, an automobile comprising the water chamber device, and a method for heating and cooling an automobile battery. Background technique [0002] In the soft pack lithium battery box used in the existing new energy vehicles, the thermal management methods include air cooling and water cooling. In the water cooling device, it is necessary to install a cooling water heating device outside the battery box inside the vehicle to increase the temperature of the battery by heating the cooling water in a low temperature environment to ensure the normal operation of the battery. [0003] Among them, the cooling water heating device is mostly arranged in the front cabin of the car, while the battery box is usually arranged under the floor of the vehicle, and the cooling water heating device is connected to the battery box through pipelines to transfer heated cooling water. Th...
