Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
Referring to fig. 1, the present invention provides a power load variation limiting method, which includes:
s1, acquiring the current output power of a vehicle electric pile and the target power required by a vehicle;
s2, determining the load variation speed of the output power of the galvanic pile according to the current output power and the target power;
and S3, limiting the load change speed when the vehicle meets the preset condition.
The preset conditions comprise at least one of the fact that the distance between the vehicle galvanic pile and the last startup exceeds a first time period, the current humidity of the vehicle galvanic pile meets the preset humidity, the current temperature of the vehicle galvanic pile meets the preset temperature, and the BOP system of the vehicle meets the preset operation conditions.
In the present embodiment, the target power is usually determined by the target speed of the vehicle, for example, when the target speed of the vehicle is 100km/h, the target power is 100kw. But the current vehicle speed is 20km/h and the current output power of the vehicle stack is 20kw. Under some conditions, the current output power is directly changed into the target power, and the load change speed of the vehicle electric pile is large and heavy. When the vehicle stack is not started for a long time (for example, the vehicle stack is not started for three months), the performance index of the vehicle stack may not reach the standard (generally, the voltage-current curve of the vehicle stack).
In another embodiment, the humidity and temperature of the vehicle stack may also affect the service life of the vehicle stack. The operating time of various components in the BOP system of a vehicle can also affect the life of the vehicle's stack.
By the method, when the electric pile meets any one of the conditions, the load change speed of the electric pile can be limited, the electric pile is protected, and the service life of the electric pile is prolonged.
Specifically, when the preset condition comprises that the distance between the vehicle stack and the last startup exceeds a first time period;
after the step of limiting the load change speed, the method further comprises the following steps:
detecting the performance index of the vehicle electric pile at a first time point after starting, and removing the limitation of the load changing speed of the vehicle electric pile when the performance index of the vehicle electric pile meets the preset performance index.
In this embodiment, the vehicle stack is not started for a long time, and the default vehicle stack performance is not satisfactory. After the vehicle stack is started, the performance of the vehicle stack may be restored above the preset performance condition, or the performance of the vehicle stack may originally meet the preset performance condition. At a first point in time (e.g., thirty minutes after start-up) after the vehicle stack is started up, it may be determined whether the performance of the vehicle stack meets a preset performance requirement. And if the current is satisfied, releasing the limitation of the load change speed of the vehicle electric pile.
Specifically, when the preset condition includes that the current humidity at which the vehicle electric pile is located meets a preset humidity;
the step of limiting the load change speed specifically comprises:
and correspondingly limiting the load change speed according to the difference between the current humidity and the preset humidity.
In this embodiment, the preset humidity may be an interval or a humidity value. For example, if the difference between the current humidity and the preset humidity exceeds 5%, the limited load variation speed is determined according to the standard load variation speed (i.e., the load variation speed without limiting the load variation speed). For example, the limited varying speed may be limited to 90% of the standard varying speed. In addition, the size of the load variation speed after limitation can be determined according to the difference between the current humidity and the preset humidity until the load variation speed after limitation reaches the lowest value. For example, if the difference between the current humidity and the preset humidity exceeds 10%, the standard load variation speed is limited to 80%. For example, the limited load variation speed is 50% of the standard load variation speed, and in this case, how large the difference between the current humidity and the preset humidity is, the load variation speed is limited to 50% of the standard load variation speed.
Specifically, when the preset condition includes that the current temperature of the vehicle electric pile meets a preset temperature;
the step of limiting the load varying speed specifically includes correspondingly limiting the load varying speed according to a difference between the current temperature and a preset temperature.
In this embodiment, the preset temperature may be 30 degrees celsius, and the current temperature and the preset temperature are greater than 5 degrees celsius, so that the load varying speed is limited to 90% of the standard load varying speed. When the temperature is higher than 10 degrees centigrade, the load change speed is limited to 80% of the standard load change speed until the load change speed is limited to the lowest load change speed (for example, 50% of the standard load change speed).
Specifically, the meeting of the preset operating conditions of the BOP system of the vehicle specifically includes:
the running time of the components of the BOP system reaches preset time, and/or the error reporting times of the components of the BOP system reach a preset error reporting threshold value.
In this embodiment, each component is included in the BOP system, and when the operating time of the component reaches a preset time (the preset time may be determined according to the design service life of the component, for example, the preset time is 80% of the design service life), it may be considered that the BOP system may cause a potential problem; when the error reporting times of the BOP system reach the preset error reporting times (for example, the error reporting times in one month is more than 3 times), the BOP system can be considered to have influenced the vehicle electric pile.
Specifically, the BOP system comprises an air compressor, a throttle valve and a cooling fan;
the step of the component running time of the BOP system reaching the preset time specifically includes that at least one of the air compressor, the throttle valve and the cooling fan reaches the preset time, and/or the step of the component error reporting times of the BOP system reaching the preset error reporting threshold specifically includes that the error reporting times of at least one of the air compressor, the throttle valve and the cooling fan reaches the preset error reporting times.
Specifically, the step of limiting the load change speed specifically includes:
when the target power belongs to a first interval, limiting the load changing speed to a first load changing speed;
when the target power belongs to a second interval, limiting the load-varying speed to a second load-varying speed;
the minimum power of the second interval is larger than the maximum power of the first interval, and the second variable load speed is larger than the first variable load speed.
In this embodiment, the target power is positively correlated with the target speed measurement. For example, the current vehicle speed is 10km/h, and the current output power is 10kw. At this time, the target vehicle speed was 100km/h, and the target output power was 100kw. Originally, the load change speed is changed from 10kw to 100kw, and the time is three seconds, and the load change speed is 40kw/s. The first interval may be set to 40kw-70kw (corresponding to a vehicle speed of 40km/h-70 km/h) with a load variation speed limited to 15kw/s. The second interval is set to 70kw-100kw (corresponding to a vehicle speed of 70km/h-100 km/h), and the variable load speed is limited to 10kw/s. Thus, the vehicle time can be changed from 40km/h to 70km/h, and the original 1 second is changed into the limited 2 seconds. 1 second from 70km/h to 100km/h becomes 3 seconds after the restriction.
It should be noted that, in the above embodiment, the present output power may also be determined according to the present current, and the target power may also be determined according to the target current. For example, the target vehicle speed is 70km/h, the target current is 70A. The present vehicle speed is 30km/h, and the present current is 30A.
