Description

A method, performed by a control device, for controlling a cooling and heating system in a vehicle.
TECHNICAL FIELD The invention relates to a method, performed by a control device, for controlling a cooling and heating system in a vehicle. The invention further relates to a computer program, a computer-readable medium, a control device, a cooling and heating system and a vehicle according to the appended claims.
BACKGROUND Propulsion batteries for vehicles and also the power electronics controlling the propulsion of the vehicle may be cooled or heated to reach an operating temperature of the propulsion batteries and the power electronics, so that electric propulsion machines in the vehicle may deliver power needed for propulsion the vehicle.
A passenger compartment in a vehicle may also be heated or cooled. A system for climatization of the passenger compartment may be adapted to regulate the temperature and the humidity in the passenger compartment.
The propulsion battery may be connected to a radiator for cooling and heating the propulsion battery. The radiator may be arranged in a space in the vehicle, which may have connection to the ambient air outside the vehicle and also to the passenger compartment. Air direction devices, such as flaps, may be arranged to open and close openings in the body of the vehicle for directing air through the radiator. Air passing the radiator may cool or heat of the propulsion battery. A cooling system for the passenger compartment, such as a passenger AC-system, may be separate from other components in a vehicle that need to be cooled.
The document EP3045331 A2 discloses a thermal management system for a vehicle comprising a battery thermal control loop connected to a passenger cabin thermal control loop by means of a four-way valve.
Vehicles of today are typically manufactured for a specific purpose, e.g. a bus is manufactured for transporting people and a truck is manufactured for transporting goods. Such vehicles are typically manufactured and completely assembled in a factory or they may be partly assembled in a factory and completed at a body manufacturer. Once the vehicle is assembled, the vehicle may be used for the specific purpose. Thus, a bus may be used as a bus and a garbage truck may be used as a garbage truck. Different vehicles are thus needed for different purposes, which may require a large fleet of vehicles and which may be very costly. It may therefore be desired to be able to customize a vehicle depending on different missions.
There are, for example, known solutions where a truck can be rebuilt by changing a concrete mixer to a loading platform. This increases the flexibility and two different functions can be achieved by means of one single vehicle. Also, document US-2016/0129958 A discloses a modular electric vehicle using interchangeable vehicle assembly modules. The user can thereby disassemble and reassemble the vehicle for use in different applications. Disassembling and reassembling such a vehicle would, however, be a very cumbersome and time consuming work. Furthermore, when a failure occurs in one of the known vehicle modules it may be difficult to replace the failing module, which may result in that the vehicle may be unusable for a considerable period of time. It may also be cumbersome to transport the replacing module to the site of the vehicle with the failing module.
SUMMARY Despite known solutions in the art, it is desired to increase the efficiency of energy storage devices in a vehicle by controlling the temperature of the energy storage devices to an operation temperature. It is also desired to effectively control the temperature of a compartment for goods and/or passengers in a vehicle. It is also desired to reduce the power needed for heating and cooling of the energy storage devices and the compartment for goods and/or passengers of a vehicle.
An object of the invention is therefore to increase the efficiency of energy storage devices in a vehicle by controlling the temperature of the energy storage devices to an operation temperature.
Another object of the invention is to effectively control the temperature of a compartment for goods and/or passengers in a vehicle.

DETAILED DESCRIPTION The vehicle according to the present disclosure may be a bus or a truck, which is provided with a compartment for transporting passengers and/or goods. The compartment may be cooled or heated for reaching a predetermined desired temperature in the compartment. The vehicle also comprises at least one energy storage device for propulsion of the vehicle. The at least one energy storage device may be cooled or heated to reach an operating temperature.
The vehicle may be a modularised vehicle, which is autonomously operated. Modularised vehicles are typically assembled at the customer’s premises and the customer may thus buy a set of modules from a manufacturer. The assembled vehicle may comprise at least two modules including at least one drive module and at least one functional module. Such a modularised vehicle is applicable on all sorts of road vehicles and may thus relate to heavy vehicles, such as buses, trucks etc., which may be used on public roads.
The method, performed by the control device, for controlling a cooling and heating system in a vehicle will effectively heat or cool the compartment for goods and/or passengers. In addition, the efficiency of the at least one energy storage device is increased. The power needed for heating and cooling the at least one energy storage device and the compartment for goods and/or passengers is reduced. The at least one energy storage device, is effectively cooled or heated to reach an operating temperature, so that electric propulsion machines in the vehicle may deliver power needed for propulsion the vehicle. The at least one energy storage device may comprise at least one energy storage unit, such as propulsion batteries, for propulsion of the vehicle. The at least one energy storage device may also comprise power electronics for controlling the least one energy storage unit and for controlling the propulsion of the vehicle.
According to an aspect, the present disclosure relates to a method, performed by a control device, for controlling a cooling and heating system in a vehicle, wherein the system comprises: a first fluid circuit for cooling and heating at least one energy storage device and a compartment for goods and/or passengers in the vehicle, the first fluid circuit comprises a heater device, a control valve and at least one radiator device; wherein the control valve is arranged to direct a first fluid in the first fluid circuit through the at least one radiator device and/or through a bypass conduit in the first fluid circuit; and wherein the at least one radiator device is arranged in connection with the compartment for goods and/or passengers, the method comprising: determining the temperature of the at least one energy storage device; determining the temperature in the compartment for goods and/or passengers; controlling the heater device based on the determined temperature of the at least one energy storage device, a predetermined desired temperature of the at least one energy storage device, the determined temperature in the compartment for goods and/or passengers and a predetermined desired temperature in the compartment for goods and/or passengers; and controlling the control valve based on the determined temperature of the at least one energy storage device, the predetermined desired temperature of the at least one energy storage device, the determined temperature in the compartment for goods and/or passengers and the predetermined desired temperature in the compartment for goods and/or passengers.
The first fluid circuit is configured for cooling and heating at least one energy storage device and the compartment for goods and/or passengers in the vehicle. Heat from the first fluid is transferred to the at least one energy storage device for increasing the temperature of the at least one energy storage device. When the temperature of the at least one energy storage device should be decreased, heat from the at least one energy storage device is transferred to the first fluid.
The heater device in the first fluid circuit is controlled based on the determined temperature of the at least one energy storage device, a predetermined desired temperature of the at least one energy storage device, the determined temperature in the compartment for goods and/or passengers and a predetermined desired temperature in the compartment for goods and/or passengers. The temperature of the at least one energy storage device may be determined by means of a temperature sensor. The predetermined desired temperature of the at least one energy storage device may coincide with an operating temperature for the at least one energy storage device. The operating temperature for the at least one energy storage device is a temperature at which the at least one energy storage device deliver power at a most efficient level for propulsion the vehicle. The determined temperature in the compartment for goods and/or passengers may be determined by means of a temperature sensor. The predetermined desired temperature in the compartment for goods and/or passengers may be about 20 °C, which is a temperature many human beings find most comfortable to stay in.
Heat from the first fluid in the first fluid circuit may be transferred through the at least one radiator device to the compartment for goods and/or passengers for increasing the temperature in the compartment for goods and/or passengers. If the temperature of the first fluid is lower than the temperature in the compartment for goods and/or passengers, the first fluid may absorb heat through the at least one radiator device from the air in the compartment for goods and/or passengers and thus lower the temperature in the compartment for goods and/or passengers.
The control valve in the first fluid circuit is arranged to direct the first fluid through the at least one radiator device and/or through a bypass conduit in the first fluid circuit. The control valve is controlled based on the determined temperature of the at least one energy storage device, the predetermined desired temperature of the at least one energy storage device, the determined temperature in the compartment for goods and/or passengers and the predetermined desired temperature in the compartment for goods and/or passengers. The bypass conduit in the first fluid circuit may direct the first fluid through the at least one radiator device for increasing or decreasing the temperature in the compartment for goods and/or passengers and/or for increasing or decreasing the temperature of the at least one energy storage device.
Alternatively, if the temperature in the compartment for goods and/or passengers should not be affected by the temperature of the first fluid in the first fluid circuit, the control valve is controlled to direct the first fluid through the bypass conduit and thus circulate the first fluid back through the at least one energy storage device. The number and size of the radiators may depend on the volume of the compartment for goods and/or passengers According to an example, controlling the control valve comprises controlling the control valve to direct the first fluid through the bypass conduit and wherein controlling the heater device comprises controlling the heater device to increase the temperature of the first fluid in the first fluid circuit for increasing the temperature of the at least one energy storage device, if the determined temperature of the at least one energy storage device is below the predetermined desired temperature of the at least one energy storage device and the determined temperature in the compartment for goods and/or passengers is above the predetermined desired temperature in the compartment for goods and/or passengers.
If the temperature of the energy storage device is below its predetermined desired temperature and the temperature in the compartment for goods and/or passengers is above the predetermined desired temperature, heated first fluid in the first fluid circuit should not pass the radiator devices in the passengers compartment. Instead, the control valve is controlled to direct the heated first fluid through the bypass conduit and further to the at least one energy storage device. The first fluid in the first fluid circuit will thus bypass the radiator devices. In addition, if the temperature in the compartment for goods and/or passengers is at the predetermined desired temperature the control valve may be controlled to direct the first fluid in the first fluid circuit through the bypass conduit and thus bypass the radiator devices in order to avoid the temperature in the compartment for goods and/or passengers to increase.
According to an example, controlling the control valve comprises controlling the control valve to direct the first fluid through the at least one radiator device for increasing the temperature of the at least one energy storage device, if the determined temperature of the at least one energy storage device is below the determined temperature in the compartment for goods and/or passengers.
Air in the compartment for goods and/or passengers having a temperature above the temperature of the energy storage device may be used to increase the temperature of the energy storage device. The control valve may be controlled to direct the flow of the first fluid in the first fluid circuit through the radiator devices, so that warm air in the compartment for goods and/or passengers will transfer heat through the radiator devices to the first fluid in the first fluid circuit. The temperature in the first fluid will thus increase after it has passed the radiator devices. Thereafter the first fluid will transfer heat to the at least one energy storage device.
According to an example, controlling the heater device comprises controlling the heater device to increase the temperature of the first fluid in the first fluid circuit for increasing the temperature of the at least one energy storage device and for increasing the temperature of the compartment for goods and/or passengers.
The first fluid in the first fluid circuit may be heated by the heater device. Thus, heat generated in the heater device is transferred to the first fluid. Since the first fluid is arranged to circulate and pass through the radiator devices and the at least one energy storage device, the temperature in the compartment for goods and/or passengers and the temperature of the energy storage device will increase when heat from the first fluid is transferred to the compartment for goods and/or passengers through the radiator devices and transferred to the second fluid and further to the energy storage device through the radiator devices. For increasing the temperature of the at least one energy storage device and for increasing the temperature of the compartment for goods and/or passengers by means of the heat in the first fluid, the control valve may be controlled to direct the first fluid through the radiator devices.
According to an example, controlling the control valve comprises controlling the control valve to direct the first fluid through the at least one radiator device for decreasing the temperature of the at least one energy storage device, if the determined temperature of the at least one energy storage device is above the predetermined desired temperature of the at least one energy storage device.
The at least one radiator device may act as a cooler for the first fluid. Thus, when the first fluid passes the radiator devices, the air passing the radiator devices may decrease the temperature of the first fluid if the temperature of the air passing the radiator devices is lower than the temperature of the first fluid. The first fluid having a decreased temperature flowing to the at least one energy storage device. At least one energy storage device, heat will be transferred to the first fluid. Since heat from the at least one energy storage device is transferred to the first fluid, the temperature of the energy storage device will decrease. The temperature of the air passing the radiator devices may increase. If the determined temperature in the compartment for goods and/or passengers is lower than the predetermined desired temperature in the compartment for goods and/or passengers, the heated air that has passed the radiator devices may be directed to the compartment for goods and/or passengers for increasing the temperature in the compartment for goods and/or passengers.

However, if the determined temperature of the at least one energy storage device is above the predetermined desired temperature of the at least one energy storage device, the control valve may be controlled to direct the first fluid through the at least one radiator for decreasing the temperature of the first fluid. The at least one air direction device may thus be controlled for directing the air that has passed the at least one radiator device away from the compartment for goods and/or passengers in order to avoid the compartment for goods and/or passengers to be heated by the air that has passed the at least one radiator.
