Detailed Description

In the present invention, the embodiments and the features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail with reference to the accompanying drawings in conjunction with embodiments.

The utility model provides a battery pack, wherein, battery pack includes casing 1, sets up module 2 and liquid cooling piece 3, setting in the casing 1 are in light receiving piece 5, orientation on the bottom surface of casing 1 light emitting piece 4, alarm 8 and battery manager 6 that light receiving piece 5 was received, battery manager 6 electricity connect in light receiving piece 5 light emitting piece 4 with alarm 8, battery manager 6 sets up to: the alarm 8 is controlled to give an alarm according to the intensity of the light received by the light receiving member 5.

The battery pack includes a case 1 and a module 2 disposed in the case 1, and the module 2 is cooled by a liquid cooling member 3 to be maintained at a proper operating temperature.

In addition, a light receiving member 5 on the bottom surface and a light emitting member 4 facing the light receiving member 5 are provided in the case 1, the light emitting member 4 emits light signals such as light beams, light rays, etc. with a predetermined light intensity and the light receiving member 5, and a battery manager 6 is connected to the light emitting member 4 and the light receiving member 5 to control the light emitting member 4 to emit the light signals and process the signals received by the light receiving member 5.

When the liquid cooling piece 3 leaks, part of the cooling liquid flows to the light receiving piece 5, the light intensity received by the light receiving piece 5 is affected, the electric signal transmitted from the light receiving piece 5 to the battery manager 6 is changed due to the change of the light intensity, and the battery manager 6 controls the alarm 8 to give an alarm according to the change of the electric signal corresponding to the light intensity, so that a user is reminded of checking the leakage condition of the cooling liquid in the battery pack in time.

The critical value of the light intensity received by the light receiving part 5 can be determined through the test data, when the detected light intensity is lower than the critical value, the battery manager 6 can control the alarm 8 to alarm and remind a user according to the corresponding electric signal, and the alarm signal can be an acoustic signal, an optical signal and the like.

In addition, the battery pack includes a humidity sensor disposed on a bottom surface of the case 1 and electrically connected to the battery manager 6, and the battery manager 6 is configured to: the alarm 8 is controlled to give an alarm according to the intensity of the light received by the light receiving member 5 and the humidity detected by the humidity sensor. When the liquid cooling piece 3 has the coolant leakage, the coolant partially flows to the bottom surface of the housing 1 (the bottom surface inside the housing), the humidity sensor can be arranged on the bottom surface, when the coolant flows to the humidity sensor (or the coolant is evaporated to cause the humidity change in the housing), so that the humidity detected by the humidity sensor is increased, the battery manager 6 controls the alarm 8 to give an alarm according to the humidity change detected by the humidity sensor, and particularly, the battery manager can be combined with the humidity change of the humidity sensor and the light intensity change received by the light receiving piece 5 to judge whether the coolant leakage occurs according to the information of two different types. Wherein, can also be according to the test data, set up the humidity critical value, when the humidity that the humidity transducer detects exceeds this critical value, can regard as there is the leakage possibility, can choose to send out the police dispatch newspaper.

Alternatively, the light receiving member 5 and the humidity sensor are disposed at the lowest point on the bottom surface of the case 1. Can set up sunken region on the bottom surface of casing 1 to receive piece 5 and humidity transducer setting with light in this region, the coolant liquid of leaking collects in sunken region department more easily, makes the coolant liquid can influence the light intensity and the humidity that the piece 5 and humidity transducer located more rapidly, and the piece 5 that receives of being more convenient for detects the light intensity change, and the humidity transducer of being convenient for detects the humidity change.

Wherein the height of the module 2 with respect to the bottom surface of the housing 1 is greater than the light receiving member 5 and the humidity sensor. When the coolant liquid that liquid cooling piece 3 leaked arrived light and receives piece 5 and humidity transducer position, its volume of leaking is less relatively, is not enough to soak module 2, that is to say, set up the height of module 2 to be greater than light and receive piece 5 with humidity transducer for when detecting preliminary leakage, the volume of leaking of coolant liquid is not enough to soak module 2, with protection module 2.

Wherein, the laminating setting of liquid cooling piece 3 is in the bottom of module 2. That is to say, the liquid cooling member 3 is located the downside of module 2, and when it leaked, the coolant liquid flowed down, can not directly flow to module 2 position, and the leakage quantity is less relatively and can not soak module 2, guarantees that module 2 is not soaked when detecting the leakage.

In addition, a support member 7 is provided on the bottom surface of the housing 1, and the liquid cooling member 3 is provided on the support member 7. As shown in fig. 1, a convex supporting member 7 is provided on the bottom surface of the housing 1, which can support the liquid cooling member 3 and the module 2 at a relatively high position, and has a distance from the bottom surface of the housing 1, so that when a small amount of leakage occurs, the cooling liquid does not soak the module, and the leakage can be timely detected by the light receiving member 5 and the humidity sensor, thereby reminding a user to detect the leakage of the battery pack.

Wherein, the liquid cooling piece 3 is a water cooling plate. The liquid cooling member 3 may be a plate-shaped structure in which a cooling liquid flow passage is provided, but of course, in other embodiments, the liquid cooling member 3 may be a cooling pipe.

Alternatively, the light emitting element 4 is a laser emitter. The light emitting element 4 can emit laser light which, unlike ordinary light, can be more easily recognized by the light receiving element 5, facilitating distinction from ordinary visible light, to more accurately detect a change in the laser beam. The light receiving member 5 may be an optical sensor, a photosensitive element, or the like.

Wherein, the light emitting piece 4 is located above the light receiving piece 5, and a bracket for supporting the light emitting piece 4 is arranged on the side wall of the shell 1. As shown in fig. 1, the light emitting element 4 and the light receiving element 5 are located at the side of the module 2, the light emitting element 4 is located above the light receiving element 5 and maintains a proper distance, and a bracket is attached to a side wall of the housing 1 to support the light emitting element 4 through the bracket. The bracket can be welded on the side wall of the shell 1, and can also be connected on the side wall of the shell 1 in a clamping manner.

Additionally, the utility model also provides a vehicle, wherein, the vehicle is provided with above scheme the battery package. The vehicle may be a fuel powered vehicle, a hybrid vehicle or an electric vehicle.
