Until the battery pack 35 is dead, an alarm is given.

In the embodiment, the load rates of the diesel generating set and the battery pack 35 can be monitored, in the process of temporarily starting the load, the real-time load rate of the diesel generating set is suddenly increased, the control module accesses the battery pack 35, and the diesel generating set and the battery pack 35 jointly supply power to the load; when the load is stable, the diesel generator set is changed to independently supply power to the load; when the real-time load rate of the diesel generator set is smaller than a certain value, in order to ensure the real-time load rate of the diesel generator set, part of the power of the diesel generator set can be distributed to the battery pack 35 for charging; the load of the diesel generator set can be guaranteed to be within a reasonable working range, damage to the diesel generator set is reduced, the service life of the diesel generator set is prolonged, and energy is saved.

According to some embodiments of the present application, optionally, the control module alarms and disconnects the connection to the load when the actual power used by the load is greater than the sum of the maximum power of the diesel-electric generator set plus the maximum power of the battery pack 35.

Therefore, when the actual use power of the load exceeds the sum of the maximum power of the diesel generator set and the maximum power of the battery pack 35, it is indicated that the diesel generator set and the battery pack 35 cannot meet the use of the load, and the connection with the load is cut off to protect the diesel generator set and the battery pack 35.

According to some embodiments of the present application, optionally, the control module acquires real-time states of the diesel generator set, the storage inverter, and the battery pack 35 through the acquisition device, and displays the real-time states through the display device; the control module induces and arranges the monitored data, stores the data into the real-time database and provides data trend, alarm and data report forms.

So, can monitor diesel generating set, the real-time status of storing dc-to-ac converter and group battery 35 through collection system to show, arrange in order, convenience of customers is directly perceived looks over.

According to some embodiments of the present application, optionally, when the real-time temperature of the battery pack 35 acquired by the acquisition device is lower than a first preset temperature, the control module supplies the cooling liquid of the diesel generator set to the battery pack 35, heats the battery pack 35 until the real-time temperature of the battery pack 35 reaches a second preset temperature, and stops supplying the cooling liquid of the diesel generator set to the battery pack 35.

In this embodiment, the coolant of the engine is divided into an external circulation and an internal circulation, and the battery device 3 radiates heat in the manner of the coolant device 4. As shown in particular in figure 3.

In this embodiment, the engine cooling module is composed of a radiator, a pipeline, a water pump, a cooling fan, a cylinder body, a cooling water jacket in the cylinder cover, and an accessory device. The engine cooling module is used for enabling the engine to be cooled moderately under any working condition, so that the engine is kept to work at a proper temperature (the temperature of the cooling liquid). The engine cooling module prevents both overheating and overcooling of the engine in winter.

The internal and external circulation of the engine cooling module typically utilizes a thermostat to control the flow of coolant through the radiator. The thermostat is installed in the path of the circulation of the cooling liquid (generally installed at the water outlet of the cylinder head), and the circulation flow path of the water is automatically changed according to the load of the engine and the water temperature, so as to adjust the cooling strength of the cooling system.

When the engine works in a normal thermal state, the temperature of the cooling liquid is higher than 80 ℃, the thermostat valve opens a channel leading to the radiator, a bypass pipe leading to the water pump is closed, and the cooling water flows through the radiator completely to form external circulation of the engine cooling liquid.

When the engine is in a cold environment or just started and the temperature of the cooling liquid is lower than 70 ℃, the thermostat valve closes a channel leading to the radiator and opens a bypass pipe leading to the water pump, water in the water jacket can only flow into the water pump through the bypass pipe from a bypass hole and is pressed into the water jacket of the engine by the water pump, and at the moment, the cooling water does not flow through the radiator and only internally circulates between the water jacket and the water pump, so that the overcooling of the engine is prevented, and the internal circulation of the cooling liquid of the engine is formed.

In this embodiment, the battery device 3 is temporarily heated by using the coolant circulating in the engine coolant, and after the coolant is used, the coolant returns to the internal circulation of the engine coolant. When the battery device 3 is overheated, the battery device 3 still needs to be cooled by the cooling liquid device 4. The two sets of cooling liquids are relatively independent and cannot influence each other.

Therefore, under an extreme cold condition, when the environment is lower than minus 10 ℃, the battery in the battery equipment 3 cannot be used, the heat generated after the diesel generator 2 is started cannot be utilized, the energy utilization rate is low, after the diesel generator 2 is started first, the cooling liquid in the engine circulates in the internal circulation, and when the temperature of the cooling liquid is about 60 ℃ to 70 ℃, the cooling liquid in the engine can be transferred to the battery pack 35 to heat the battery in the battery pack 35, the heated cooling liquid is recycled, namely the heat generated after the diesel generator 2 is started is provided for the battery in the battery pack 35 to be used, so that the temperature of the diesel generator 2 is effectively utilized, the battery in the battery pack 35 is helped to enter the proper use temperature, and the energy utilization rate is improved.

As shown in fig. 4-7.

In this embodiment, the cooling liquid may be divided into a plurality of portions by the liquid inlet pipe 32 to cool the plurality of battery packs 35, and the portions are collected together after cooling and returned to the cooling liquid device 4 through the liquid outlet pipe 33.

The battery device 3 comprises a rack 34, more than two layers of battery packs 35 and a battery management module 36, wherein the more than two layers of battery packs 35 are sequentially arranged on the rack 34 along the vertical direction, the battery management module 36 is arranged on the rack 34, and all the battery packs 35 are electrically connected with the battery management module 36; the bottoms of all the battery packs 35 are provided with a channel 31 for cooling liquid to pass through, the liquid inlet pipeline 32 is connected with one end of the channel 31 through a first collecting joint, and the other end of the channel 31 is connected with the liquid outlet pipeline 33 through a second collecting joint.
