example 1

[0019] Such as figure 1 As shown, it is characterized in that: the heat dissipation unit, the preheating unit and the control unit are arranged on the same side plate 1, and are all symmetrically installed on the lateral sides of the foam aluminum box 9, and the anti-collision unit Symmetry is installed on the longitudinal both sides of foamed aluminum casing 9. The box cover 6 is installed on the upper surface of the foamed aluminum box 9; the side plate 1 is symmetrically installed on the lateral sides of the foamed aluminum box 9 through the positioning rod 5 and the positioning groove 12; the three fans of the heat dissipation unit 4. Three heat dissipation heat pipes 2, three heating heat pipes 3 of the preheating unit, a controller 10, and an auxiliary power supply 11 are sequentially installed on the side plate 1; one end of the spring damper 16 is installed on a longitudinal surface of the aluminum foam box 9, The other end is installed on the damper mounting base 7; ...

example 2

[0024] The working process of a new type of vehicle battery cooling and preheating and anti-collision system of the present invention is as follows:

[0025] 1. The heat dissipation unit and preheating unit of this system start to work when they get the command to unlock the central control door, and stop working 5 minutes after they get the command to lock the door from the central control

[0026] 2. When the temperature sensor set in the aluminum foam box 9 senses that the box temperature is 30°C~40°C (the temperature at both ends of the interval only includes 30°C), the foamed aluminum box and the phase change material set in the foamed aluminum box will and the two fans 4 installed on the side plate 1 for primary heat dissipation; when the temperature is between 40°C and 50°C (the temperature at both ends of the range only includes 40°C), four fans 4 are turned on on the basis of the primary heat dissipation for heat dissipation. Two-level heat dissipation; when the tempe...

Abstract

The invention discloses a novel vehicle battery scattered preheating and collision prevention system, which relates to the technical field of vehicle battery safety. The system comprises a heat dissipation unit, wherein the heat dissipation unit is used for dissipating heat of a vehicle power battery which generates a large amount of heat in the charging and discharging process; A preheating unitfor preheating a vehicle power battery under a low temperature environment; An anti-collision unit for carrying out collision safety protection on a vehicle power battery; A control unit for controlling the staged start-up of the heat dissipation unit and the preheating unit by sensing the temperature range of the battery pack. As that unit can effectively solve the practical problem of high-temperature flammability, low-temperature charging / discharging efficiency and weak protection strength of the vehicle battery, the system can effectively improve the char / discharging efficiency and the protection level of the vehicle battery, prolong the service life of the vehicle battery, and ensure the use safety of the vehicle battery.

Description

technical field [0001] The invention relates to the technical field of vehicle battery safety, in particular to a novel vehicle battery heat dissipation and preheating and anti-collision system. Background technique [0002] In recent years, the electric vehicle industry has developed vigorously. As the total power source of electric vehicles, the performance of vehicle power batteries is the main potential factor restricting the current development of electric vehicles. On the one hand, during the high-rate charging and discharging process of the power battery, its internal chemical reaction is complex, accompanied by the release of a large amount of heat, and the gradually accumulated heat will eventually cause the internal temperature of the power battery pack to rise sharply, exceeding the high-efficiency charging and discharging temperature range of the power battery. The upper limit greatly reduces the working performance of the battery, shortens the service life of th...
