Suppose you have accepted a task to design a monitor circuit for a new and battery-based power system. What strategy would you take to optimize the cost and manufacturability of the design? The initial consideration will be to determine the system The preferred structure and location of the battery and related electronic components. After the basic structure is clear, the next issue that must be considered is the trade-off and coordination of circuit topology, for example, how to optimize the communication and interconnection of the final product.

After the basic structure is clear, the next issue that must be considered is the trade-off and coordination of circuit topology, for example, how to optimize the communication and interconnection of the final product.

　　The external dimensions of the battery will have a significant impact on the structure of the power system. Do you want to use a large number of small batteries to fit a battery module (or battery pack) with a complicated shape? Or use a battery with a large external size, which limits the number of batteries or other size restrictions due to weight issues? This may be The most variable part of the design is because the new-looking batteries are constantly on the market, and people are constantly working hard to ensure that the battery module or battery pack is integrated into the product to be more consistent with the entire product concept. For example, in the case of car design, batteries may eventually be scattered in certain spaces on the vehicle. If these spaces are not equipped with batteries, the utilization efficiency is very low.

　　Another consideration is the interconnection of test signals and/or telemetry signals between the battery (or modular battery pack), the battery management system (or its subsystems), and the final application interface. In most cases, a shell can be made to integrate certain data acquisition circuits in the battery module or battery pack, so that if it needs to be exchanged, important information such as production ID, calibration, and usage specifications can be brought along with the replaceable components. go. This type of information may be useful for battery management systems (BMS) or maintenance equipment, and minimizes the number of high-voltage rated wires required in the wiring harness.
