Battery capacity configuration principles я To meet the continuous discharge condition of accident power outage, the accident time is selected as 1 hour; я The remaining capacity when closing at the end of discharge shall not be less than 25% of the rated capacity; я Ensure that the DC bus voltage does not drop by more than 10% when an impact load occurs; я For maintenance-free batteries, the closing current generally does not exceed 4C; я Considering the capacity attenuation when the battery pack ages at the end, the reserve coefficient is selected to be 1.2; я The specific capacity design can refer to relevant national standards and technical information provided by battery manufacturers.
6. Structural characteristics and number of cabinets 1. Structural features я The front of the cabinet is a whole glass door and the back is a double door, with a beautiful and elegant appearance; я The cabinet structure design facilitates equipment installation, debugging, maintenance, inspection and operation; я The overall dimensions are available in two standard specifications: 2260Ч800Ч600mm and 2360Ч800Ч600mm. 2. Number of cabinets The number of cabinets is related to the number of modules, the number of feeder loops, battery capacity and model, DC voltage level and other factors. Generally, they are: (Take 220V system as an example, cabinet size:
2260Ч800Ч600mm) Capacity (Ah) 10~60 80~120 150~200 250~350 400~500 600~800 1000 7~8 single group Battery 1 2 3 4~5 5~6 9~10 Number of sides double group 2 3 5 12~14 14~17 6~7 10~12 Battery Note: Batteries with a capacity of 200Ah or above can be installed with a battery rack. —-6--
