Problems solved by technology

However, this solution cannot solve the constant temperature environment when the power battery is working in a low temperature environment without preheating the external charging power source, so that the power battery cannot be effectively charged and discharged, especially when parking in the wild, it will cause the electric vehicle to break down.

Embodiment

[0070] When the vehicle is in a stationary state, all electronic control parts of the vehicle have no need for cooling or preheating, and the vehicle is not charging, at this time, all solenoid valves are closed, and all four-position three-way valves are fully charged. Closed state (any two roads are not connected), thus ensuring the storage of thermal energy in the thermal energy storage tank.

[0071] Such as Figure 4 The pipeline status of the power battery that requires preheating is shown: when the vehicle is in the charging state, the system controller will control the heater integrated in the thermal energy storage tank to electrically heat the antifreeze in the thermal energy storage tank through the vehicle charging power supply , until the temperature of the antifreeze in the thermal energy storage tank reaches the desired temperature (eg 100°C).

[0072] No matter what state the vehicle is in, when the system controller detects that the capacity of antifreeze in ...

Abstract

The invention discloses an energy storage type thermal management system for an electric vehicle. The energy storage type thermal management system comprises a system sensor, a system controller and an electric control part, wherein the system sensor is connected with the system controller and used for monitoring the operating state of the overall energy storage type thermal management system in real time and transmitting the monitored signal to the system controller; the system controller is connected with the electric control part and used for receiving the signal transmitted by the system sensor, processing the received signal and controlling the electric control part in real time; and the electric control part is used for executing the signal transmitted by the system controller. A thermal energy storage tank is adopted to recycle, store and reuse the thermal energy generated by the power motor, the power storage battery and other electric control part in the operating process of the electric vehicle, so that the energy of the electric vehicle is effectively reduced while the cruising power of the electric vehicle is improved; and in addition, the heating function to the vehicle is realized by the hot air function through a PTC and the auxiliary heating through the liquid thermal energy in the thermal energy storage tank.

Description

technical field [0001] The invention belongs to the technical field of vehicle thermal management systems, and in particular relates to an electric vehicle energy storage thermal management system. Background technique [0002] Since the thermal management system of an electric vehicle involves the effective work of the power battery, the thermal management system of an electric vehicle is to some extent more complicated than that of a fuel vehicle, and it is more difficult to solve the heat problem. This is because electric control components such as power motors of electric vehicles need to dissipate heat during work, and power batteries need to maintain a constant temperature range to work properly. Especially in cold areas, when the ambient temperature is lower than 0°C, the charging and discharging function of the power battery of electric vehicles will be seriously ineffective. The power storage battery of the electric vehicle has reached the normal charge and dischar...
