Paralleling strings together greatly increases the complexity of managing the battery pack and should be avoided unless there is a specific reason to use this configuration. In this setup, each string must essentially be treated as its own battery pack for a variety of reasons. In a below example, 2 strings of 8 cells each are placed in parallel.
When the BMS and thermal management system jointly controls or manages several modules, this unified whole is called a battery pack. A battery pack is a power
Test Setup: The battery pack is placed in a controlled environment, often within a test chamber, where the voltage is applied. The setup ensures that the voltage is applied uniformly across the pack and its components.
One of the major validation and safety challenges to be tackled in modern EVs, HEVs, and PHEVs concerns the effective testing of the Battery Pack itself and the Battery Management Systems (BMS) – the complex

Safety is paramount in battery testing. When testing batteries that are hazardous by nature, safety should be a major part of your battery test setup. The details of safety requirements are often something customers think
Advantages of Battery Pack. An advantage of a battery pack is the ease with which it can be swapped into or out of a device. This allows multiple packs to deliver extended runtimes, freeing up the device for continued use while charging the removed pack separately.
New technologies in development promise to test larger Li-ion packs, but this may extend the test to a few minutes to accommodate low frequency sampling. Capacity is
Plant a LOT of lightning rods. I use a field setup where I have a paved square in the middle with a scarecrow, lamppost, and 2-4 lightning rods, surrounded by crops. I then have as many of those fields as I can fit into the farm, so I end up with dozens of battery packs after every storm.
Before the vibration test, performance tests, including capacity, insulation, and airtightness, were conducted on the battery pack. The vibration test was performed after confirming that all functions were normal. The battery pack was secured to the vibration table using fixtures, and the method of securing the battery pack and the bolt
and PHEVs concerns the effective testing of the battery pack itself and the battery management systems (BMS) – the complex electronic system that manages the performance and safety of the battery pack and the high levels of electrical energy stored within. In the sections below, I will describe both the battery pack and the BMS in greater detail.

Battery module and pack testing involves very little testing of the internal chemical reactions of the individual cells. Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics.
Engineers also check for any malfunction, temperature rise in the battery pack, current carrying capacity, cooling capacity, and overall mechanical structure. After complete testing, packs may undergo extra testing to simulate the typical conditions and be integrated into the system or end-product.
Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics. Common performance-based tests include drive-cycles, peak power capability, BMS software validation, and other application-specific characterization
Diagram of battery module and pack testing in design and manufacturing. There is significantly less time available to test during production due to high throughput. Typically the system validation done on the pack level can easily take upwards of 6 minutes per unit.
Key fundamentals of battery testing include understanding key terms such as state of charge (SOC); the battery management system (BMS) which has important functions including communication, safety and protection; and battery cycling (charge and discharge) which is the core of most tests.
There is significantly less time available to test during production due to high throughput. Typically the system validation done on the pack level can easily take upwards of 6 minutes per unit. For example, an EV battery manufacturer may plan to manufacture up to 40,000 or more battery packs a year.
