We intend to use the AD8280 safety environment. The content description of the self test is rather slight in the datasheet.
As the diagnostic is a very important part of our project, we need to know what is precisely performed in the self-test…
Is there a way to design a reconfigurable (i.e. via microcontroller FW and some analog switches) AD8280 design in order to implement one board for 3 to 6 cells connected in series? The number of battery stacked should be a FW hard-coded parameter.
We have selected the AD8280 as a secondary safety monitor in our BMS for a LiFePO4 stack.
In working on the design I have run into a few apparent internal inconsistencies in the data sheet that I would like to have resolved before going into…
Our customer is looking for hardware-only safety monitor.
They are going to use 12V lithium ion battery stacks.
The system is going to use 4 cells.
The power will drop to 6[V].
They are going to use cell balance IC (not ADI) but they want to secure…
I'm using the AD8280 in a Lithium Polymer Battery Pack Monitoring System as safety device (together with the AD7280A device used as main monitoring device).
While testing the system functionality I found that the trip points of Overvoltage…
I already emailed the product owner of the AD8280 regarding your question. I will get back to you as soon as I hear anything.
I am not familiar with how parallel batteries are monitored, balanced and protected.
Analog Devices has some devices for series connected LI batteries such as the AD7280A and AD8280.
ADI offers the main components required for a complete Li-ion…
I am not familiar with these type of batteries but in general Lithium batteries need to be charged with a constant current until they reach full charge, and then you scale back the current (CC + CV loop)
This is typically implemented in integrated…
通常，小型/中型混合动力汽车所需的电池电压在60 V至200 V之间。镍氢电池在这些电压和能量级别上有一定的优势。然而，完全混合/插电式混合动力或纯电动汽车通常需要300 V以上的电池组，锂电池正是理想之选。 据业界市场咨询公司的公开数据显示，目前锂电池电动车的市场份额在2.5％左右，预计三年之内将达到20％。
