The pressure in the pipe does not drop in the wide section, if there is no resistance. The entire pressure drop of the fluid is across the narrow section, just as the voltage only drops across the resistor. Figure (PageIndex{4}), where a pump plays the role of the battery, and a narrow pipe that of a resistor. Example (PageIndex{1}) Two resistors, of (2Omega) and (4Omega

6 FAQs about [Battery pack wide voltage circuit schematic]

What is a battery pack design?

This design focuses on e-bike or e-scooter battery pack applications and is also suitable for other high-cell applications, such as a mowing robot battery pack, 48-V family energy storage system battery packs, and so forth. It contains both primary and secondary protections to ensure safe use of the battery pack.

What are the requirements for a battery pack?

In accordance with these requirements, the inductor, its maximum current, and other circuit element parameters must be selected. For this application, the battery pack consists of 12 NiMH cells with a nominal capacity of 1700 mAh. The maximum load current of the application is 500 mA.

How do you pull up a battery pack VCC?

The electrical path to pull up the battery pack VCC passes through the host capacitance from Pack+ to Pack–, through a substrate diode in the host interface driver from VSS to the commu-nication or interface line, and through a substrate diode from this line to VCC in the battery-pack circuitry. The complete path is shown in Fig. 6.

How does a dw01 IC protect a battery pack from overcharging?

The Gate of the right pair of MOSFETs which are responsible for protecting the battery pack from overcharging is connected to the positive terminal of the battery pack. When the battery is overcharged, the DW01 IC will sense the overcharge condition using the internal potential divider circuit and will turn on the OD transistor.

What is the primary protection on a battery pack?

It contains both primary and secondary protections to ensure safe use of the battery pack. The primary protection protects the battery pack against all unusual situations, including: cell overvoltage, cell undervoltage, overtemperature, overcurrent in charge and discharge, and short-circuit discharge.

How many NiMH cells are in a battery pack?

For this application, the battery pack consists of 12 NiMH cells with a nominal capacity of 1700 mAh. The maximum load current of the application is 500 mA. The balancing is active during the charging period, to maintain an equal state of charge (SOC) for each cell at the end of charge.
