Problems solved by technology
[0004] 1. The existing distribution network power supply device cannot automatically adjust the charging voltage of the battery according to the ambient temperature change;
[0005] 2. In the distribution network power supply system, the battery is in the state of floating charge for a long time, which will lead to high temperature and short life of the battery. If the battery is detached from charging, it cannot guarantee the uninterrupted power supply function when the AC power disappears. The existing distribution network power supply device It is impossible to completely separate the charging circuit and discharging circuit of the battery;
[0006] 3. The existing distribution network power supply device cannot realize battery cycle charging control

The invention relates to a distribution network power supply apparatus. On a basis of compensation on output voltage according to battery temperature, battery charging / discharging control loops are added to enable a battery charging loop and a battery discharging loop to be managed independently, and the cycle charging for the battery is realized; by independently managing the battery charging loop and the battery discharging loop, when the battery charging loop is controlled, the battery discharging loop is not affected so as to ensure an uninterruptible power supply function of the distribution network system; when the charging loop is switched off, the battery is in a storage state; the cycle charging mode changes the working mode of the battery in most time; a long-term floating charge mode of the battery is changed into the storage state after the battery is fully charged; and therefore, the service life of the battery is greatly prolonged on the basis of the temperature compensation, and the uninterruptible power supply function is ensued as well.
Description
technical field [0001] The invention relates to a distribution network power supply device. Background technique [0002] The distribution network power supply device is the core component of the power supply system of the distribution network power supply, which can convert the input terminal voltage into the appropriate voltage required by the power supply object. Since the distribution network power supply system requires the distribution network power supply device to have the function of uninterrupted power supply after the AC power disappears, this requires the distribution network power supply system to be equipped with energy storage components, such as batteries. As an important part of the distribution network power system, the battery is a key component to ensure the uninterrupted power supply of the distribution network power system after the AC power disappears. The amount of its energy storage determines the working time of the distribution network power system...
