We are planning to use the AD7280A in Lithium Ion Battery Management system.
Before evaluation I have below queries
1- What is the principle of cell-balancing in AD7280A
2- Is cell balancing possible without controller.
Please help to suggest.
1. The Cell Balancing function is activated by the cell balance register ( see page 30 of the datasheet ), one bit represents each output. Additionally, the AD7280A offers a way of automatically enabling and disabling the CB outputs by means of a timer using the CBx timer registers. In this way a timer can be switched on which enables any CB output and then turns off after the timer has elapsed.
2. An external controller (SPI Master) is required to control the AD7280A and configure the device as required.
Can you implement the Cell balancing 0n LTC6813 throungh a Linduino One Demo Circuit 2026C on the DC2350, please use command 12 for Discharge and command 13 for Clear Charge. the Discharged cell sprint should be very close to 0.000V?
