When the current needs to be adjusted, the charging current can be controlled in time to balance the heat balance of the environment in which the battery charger is located.

Referring to FIG. 2, another embodiment of the charging current control method in the embodiment of the present application includes:

201. Determine a current condition of an influencing factor of the at least one battery charger;

Step 201 in this embodiment is the same as step 101 in the embodiment shown in FIG. 1, and details are not described herein again.

202. When the influencing factors include multiple, prioritize the multiple influencing factors;

In this embodiment, after determining the current situation of the influencing factors of the at least one battery charger, when the influencing factors include multiple, the multiple influencing factors may be prioritized.

Specifically, the influencing factors in this embodiment may include, but are not limited to, at least one of a fan operating state, a mains voltage, an ambient temperature, and an inverter load. Assuming that the influencing factors can include four types of fan operating conditions, mains voltage, ambient temperature, and inverter load, the fan operating state, mains voltage, ambient temperature, and inverter load can be sorted according to the preferred level, such as according to priority. After sorting from high to low, the sorting results can be such as: fan operating state, mains voltage, ambient temperature (parallel to the inverter load).

Among them, in the UPS system, when the AC mains power is normal, the AC mains voltage can be rectified to obtain a DC voltage, that is, the AC is converted into DC, and then the DC voltage is inverted into an AC voltage, that is, the DC inverter is AC. To charge the load and charge the battery pack through the battery charger. It can be seen from this that the inverter load is the output power when the DC voltage is inverted into an AC voltage and supplied to the load.

It can be understood that the foregoing description of the priority of the influencing factors in the embodiment is only an example. In an actual application, the priority may be set according to actual needs, for example, the battery may be charged when an abnormality occurs according to the influencing factor. The magnitude of the influence degree of the device is set to a higher priority. If the degree of influence on the battery charger is greater, the priority of the influencing factor is higher, and is not specifically limited herein.

203, determining whether the charging current of the battery charger needs to be adjusted according to the current condition of the influencing factor corresponding to the first priority, if not, executing step 204, and if yes, executing step 205;

In this embodiment, after prioritizing a plurality of influencing factors, whether the charging current of the battery charger needs to be adjusted may be determined according to the current situation of the influencing factors corresponding to the first priority.

For example, suppose the influencing factors may include four types of fan operating state, mains voltage, ambient temperature, and inverter load. After sorting according to the principle of priority from high to low, the sorting result is: fan operating state, mains voltage , ambient temperature, inverter load, you can first determine whether the charging current of the battery charger needs to be adjusted according to the current status of the fan operating state. If adjustment is needed, the charging current of the battery charger can be adjusted according to a preset rule. On the contrary, it can continue to judge whether the charging current of the battery charger needs to be adjusted according to the current state of the commercial power voltage, and so on.

That is, when the influencing factors include a plurality of factors, determining whether the charging current of the battery charger needs to be adjusted according to the current condition includes:

Prioritizing a plurality of the influencing factors;

Wherein, when the influencing factor is the operating state of the fan, determining whether the charging current of the battery charger needs to be adjusted according to the current situation includes:

Check if the fan running status is normal. If not, determine that the charging current needs to be adjusted.

Specifically, the fan can be disposed in the cabinet where the battery charger is located, and the fan can perform heat dissipation processing on the cabinet where the battery charger is located. When the fan is running normally, the default can be the heat dissipation condition of the environment where the battery charger is located, and the battery can meet the demand. The charging current of the charger does not need to be adjusted. When the fan is running abnormally, if the fan stops, the default condition of the battery charger is insufficient. If the battery charger is still charging with the original charging current, it may cause If the thermal balance of the environment in which the battery charger is located is destroyed, the charging current of the battery charger needs to be adjusted.

When the influencing factor includes at least two of a fan operating state, a mains voltage, an ambient temperature, and an inverting load, and determining that an influencing factor corresponding to the current priority is a fan operating state, the judging according to the current situation Whether the charging current of the battery charger needs to be adjusted includes:

The charging current is lowered to a first threshold.

When the influencing factor is the mains voltage, it is determined whether the charging current of the battery charger needs to be adjusted according to the current situation, including:

It is detected whether the mains voltage is lower than the preset voltage threshold, and if so, it is determined that the charging current needs to be adjusted.

Specifically, the mains voltage is generally supplied at a voltage of 220V. When the mains voltage is lower than a preset voltage threshold, such as 176V, the charging current of the battery charger will be limited, and the charging current of the battery charger needs to be performed. Adjustment.

When the influencing factors include at least two of a fan operating state, a mains voltage, an ambient temperature, and an inverter load, and determining that an influencing factor corresponding to the current priority is a mains voltage, the judging according to the current situation Whether the charging current of the battery charger needs to be adjusted includes:

The charging current is lowered according to the mains voltage.

When the influencing factor is the ambient temperature, it is determined whether the charging current of the battery charger needs to be adjusted according to the current situation, including:

Check if the ambient temperature is higher than the preset temperature threshold. If yes, determine that the charging current needs to be adjusted.

Specifically, the ambient temperature of the environment in which the battery charger is located can directly reflect whether the thermal balance is damaged. When the ambient temperature of the battery charger is maintained below a preset temperature threshold, the current heat generation and heat dissipation of the battery charger can be considered to be balanced. When the ambient temperature of the battery charger is higher than the preset temperature threshold, it can be considered that the heat dissipation condition of the environment of the battery charger is insufficient or the heat generation of the battery charger is increased, and the charging current of the battery charger needs to be adjusted.

When the influencing factor includes at least two of a fan operating state, a mains voltage, an ambient temperature, and an inverter load, and determining that an influencing factor corresponding to the current priority is an ambient temperature, the determining according to the current situation Whether the battery charger's charging current needs to be adjusted includes:

The charging current is lowered to a second threshold.

When the influencing factor is the inverter load, it is determined whether the charging current of the battery charger needs to be adjusted according to the current situation, including:

It is detected whether the inverter load is higher than the preset load threshold, and if so, it is determined that the charging current needs to be adjusted.

Specifically, the inverter load is converted as a DC voltage as part of the AC voltage. When the inverter load is higher than the preset load threshold, the charging current of the battery charger can be adjusted to appropriately reduce the charging power, and the inverter output power is preferentially guaranteed. To ensure that charging and inverter work properly. Wherein, the preset load threshold is determined by the DC voltage inversion being the rated output power of the AC voltage, and the preset load threshold may be a preset percentage of the rated output power, for example, the rated output power is 1000 W, when the inverter load It should not exceed 50% of the rated output power (ie, the inverter load can be up to 150% of the rated output power). If the inverter load is 1600W, the inverter load is higher than the preset load threshold.

When the influencing factor includes at least two of a fan operating state, a mains voltage, an ambient temperature, and an inverter load, and determining that an influencing factor corresponding to the current priority is an inverting load, the judging according to the current situation Whether the charging current of the battery charger needs to be adjusted includes:

The adjusting the charging current according to a preset rule includes:

The charging current is lowered to a third threshold.

204, determining whether the charging current needs to be adjusted according to the current situation of the influencing factors corresponding to the second priority, if yes, executing step 205, if not, executing step 203;

In this embodiment, when the current state of the influencing factor corresponding to the first priority determines that the charging current needs to be adjusted, whether the charging current needs to be adjusted may be determined according to the current condition of the influencing factor corresponding to the second priority. The first priority is higher than the second priority.

For example, following the example described in step 203, it is assumed that the influencing factors may include four types of fan operating states, mains voltage, ambient temperature, and inverter load. After sorting according to the principle of priority from high to low, the sorting result is: Fan operation status, mains voltage, ambient temperature, and inverter load. If the current status of the fan operation status is judged, the charging current of the battery charger does not need to be adjusted. If adjustment is needed, it can continue to judge according to the current status of the mains voltage. Whether the charging current of the battery charger needs to be adjusted. The operating state of the fan can be used as the influencing factor corresponding to the first priority, and the utility voltage can be used as the influencing factor corresponding to the second priority. If the charging current of the battery charger is not required to be adjusted according to the current state of the commercial voltage, Then, it can continue to determine whether the charging current of the battery charger needs to be adjusted according to the current situation of the ambient temperature. At this time, the ambient temperature will be the influencing factor corresponding to the first priority, and the inverter load will be the influencing factor corresponding to the second priority. .

205. Adjust the charging current according to a preset rule;

In this embodiment, when it is determined that the charging current of the battery charger needs to be adjusted, the charging current may be adjusted according to a preset rule.

Specifically, according to the priority level, the charging current of the battery charger needs to be adjusted according to the current situation of the influencing factors, and the current state of the influencing factor of the previous priority determines that the charging current of the battery charger needs to be adjusted. , the charging current can be adjusted according to a preset rule, and it is not necessary to determine whether the charging current of the battery charger needs to be adjusted according to the current condition of the influencing factor corresponding to the subsequent priority, and vice versa, it is necessary to continue to correspond according to the next priority. The current condition of the influencing factor determines whether the charging current of the battery charger needs to be adjusted, and so on, until it is determined whether the charging current of the battery charger needs to be adjusted according to the current condition of the influencing factor corresponding to the lowest priority. In practical applications, when the current state of an influencing factor determines that the charging current needs to be adjusted, the charging current may be adjusted according to a preset rule corresponding to the influencing factor.

Wherein, when the influencing factor is the operating state of the fan, the charging current can be lowered to a first threshold, such as 1A; when the influencing factor is the mains voltage, the charging current can be adjusted according to the mains voltage, for example, charging can be performed according to different voltages. The current is linearly derated; when the influencing factor is ambient temperature, the charging current can be lowered to a second threshold, such as 4A; when the influencing factor is an inverter load, the charging current can also be lowered to a third threshold, in practice. In the application, since the inverter load is associated with the ambient temperature, optionally, the second threshold may be the same as the third threshold, such as 4A.

Wherein, when the current condition of any influencing factor determines that the charging current of the battery charger does not need to be adjusted, the other operations may be omitted, that is, the flow is ended, so that the battery charger is charged with the current charging current.

When the charging current needs to be adjusted, the priority order of the two influencing factors of the fan operating state and the mains voltage can be further determined, and the second target influencing factor of the fan operating state and the highest priority among the mains voltage can be determined, for example, If the priority of the fan operating state is higher than the priority of the mains voltage, the fan operating state is the second target influencing factor.
