Capacity and number of channels of the container
The capacity and number of channels of a container have the following relationship:
1、 The impact of capacity on the number of channels
Overall power allocation: The total capacity of the distribution cabinet determines the total power that can be provided for each channel. If the capacity of the distribution cabinet is small, then in the case of a large number of channels, the power allocated to each channel will be relatively low. For example, a 10kW capacity distribution cabinet with 100 channels can allocate an average of approximately 100W of power per channel; If there are only 10 channels, each channel can be allocated 1kW of power. This means that when the capacity is constant, the more channels there are, the smaller the charging and discharging power that a single channel can carry.
Balancing testing efficiency and accuracy: In practical applications, increasing the number of channels can improve testing efficiency and enable simultaneous capacity testing of more batteries. However, if there are too many channels and the capacity of the distribution cabinet is limited, it may lead to a decrease in the testing accuracy of each channel. Because conducting charge and discharge tests at low power may affect the stability of current and voltage, thereby affecting the accuracy of capacity measurement. For example, for some batteries that require high precision, such as high-end electronic products or electric vehicle power batteries, precise testing may be required at high power. At this time, the number of channels should not be too many to ensure that each channel has sufficient power to meet the precision requirements.
2、 The impact of channel quantity on capacity
Demand driven capacity design: The number of channels is usually determined based on actual production or testing requirements. If a large number of batteries need to be tested simultaneously, a larger number of channels are required. And this in turn will affect the capacity design of the distribution cabinet. Generally speaking, the more channels there are, the larger the capacity of the distribution cabinet needs to be in order to meet the power requirements of each channel. For example, if a manufacturer needs to test thousands of batteries every day, they may need a distribution cabinet with hundreds of channels. In order to ensure that each channel can work properly, the capacity of the distribution cabinet needs to be designed relatively large, which may require tens of kilowatts or even hundreds of kilowatts of capacity.
Cost and space considerations: Increasing the number and capacity of channels will increase the cost and space occupation of the distribution cabinet. More channels mean more electronic components, circuits, and control systems are needed, which increases the manufacturing cost of the equipment. At the same time, high-capacity distribution cabinets usually occupy more space, requiring larger installation sites and cooling facilities. Therefore, when designing a capacity divider, it is necessary to comprehensively consider the balance between the number of channels and capacity, in order to meet actual needs while controlling costs and space occupation.
In summary, the capacity and number of channels of a container have a mutual influence. When selecting a container, it is necessary to comprehensively consider the relationship between the two based on actual testing requirements, accuracy requirements, cost, and space, in order to choose the most suitable container.
