6 FAQs about [How to discharge the battery in the module room]
How should a battery room be designed?
Battery rooms shall be designed with an adequate exhaust system which provides for continuous ventilation of the battery room to prohibit the build-up of potentially explosive hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
How a battery discharge process is performed in safe conditions?
For the discharge process to be performed in safe conditions, besides gathering information about the battery’s capacity, SoC and SoH at the beginning of the process it is necessary to monitor the temperature and voltage of individual modules, preferably even groups of cells, as well as to control the discharge current.
How do you discharge a battery?
One common manual discharge technique is to use a resistor as the load. The resistance value should be chosen based on the battery’s voltage and capacity to ensure the load current is within safe limits. This method is simple and inexpensive, but it can be inefficient and generate a lot of heat, which can shorten the battery’s lifespan.
How does a MCU discharge a battery?
For the actual discharge, the MCU sends an I2C write command to set PMID to be powered by VBAT only, and to convert /PG to a general purpose open drain output. Assuming the 200-Ω resistor is connected between PMID and /PG, this allows exclusively battery current to be sunk through the resistor.
What are manual discharge techniques?
Manual discharge techniques involve connecting an external load to the battery to drain its charge. This can be done using a battery discharger or any other load that is suitable for the battery’s specifications. The load current should be monitored to prevent over-discharging and damage to the battery.
How does a battery discharge work?
This rate of discharge decreases as the battery voltage is decreased since the resistor sinking the current is fixed, but the discharge is only necessary until the battery voltage reaches a safe threshold. To accelerate this process, power can be burned by turning ON peripherals on the module which cannot be seen.
