Battery parameter setting in DA14683

Hi Diaglog teams,

Please help me to check how modify the following parameter when useing new battery.

static const int16_t vol_dis_low_0[VOL2SOC_LUT_SIZE] = {
        3391, 3430, 3481, 3528, 3564, 3595, 3639, 3689, 3740, 3797, 3883
};
static const int16_t vol_dis_high_0[VOL2SOC_LUT_SIZE] = {
        3633, 3676, 3730, 3779, 3818, 3850, 3891, 3939, 3988, 4042, 4123

Hi xuguodong,

Hi xuguodong,

The VOL2SOC_LUT_SIZE is the size of the Look-Up Table (LUT) that converts the volts to SoC (State-Of-Charge). The constant tables vol_dis_low_0 and vol_dis_high_0 are determined according to the battery characterization. These values are  according to your battery, so you should characterize your battery first.

You can also check the following application note:

https://www.dialog-semiconductor.com/sites/default/files/an-b-035_da1468x_battery_charging_1v1.pdf

This document describes the battery charging operation for a lithium-ion or lithium-polymer battery using the DA1468x device.

Thanks, PM_Dialog

Hi Diaglog teams,

Hi Diaglog teams,

What's the difference between vol_dis_high_0 and vol_dis_low_0? 

Which characteristics do vol_dis_high_0 and vol_dis_low_0 correspond to respectively?

Thanks

Hi Diaglog teams,

Hi Diaglog teams,

Refer to  6.7 Battery Profiling and 6.7.1 Configuration of um-b-075_da1468x_state_of_charge_functionality_v1.2_0.pdf ,

1.How to generate battery profile and where does B come from?

2.Where does the tool: Generate Battery Profile of 6.7.1 Configuration?

Thanks.

Hi xuguodong,

Hi xuguodong,

Section 6 aims demonstrating how to do battery profiling. The described procedure should be done in the Windows OS. Also you will need .NET Framework 4.5  which is included with the installer NI-488.2 with .NET framework 4.5 language support.

Please find below a link to download the NI-488.2.  I have tested it with the lowest version (17.6). To do so, if the later versions are not working, please use version 17.6.

https://www.ni.com/nl-nl/support/downloads/drivers/download.ni-488-2.html#329025

As soon as it is downloaded, start the installation and follow the “Right” photo in Figure 6. Make sure that you have installed the .NET 4.5 Development Support and .NET 4.5 Runtime Support. Click in the first option of the drop-down menu. After that, please proceed with the installation and restart your PC.

Open the Battery Profiler for DA1468x which is installed together with the SmartSnippets.

It is located under C:\Program Files (x86)\Dialog Semiconductor\Battery Profiler for DA1468x windows path.

Follow the procedure described in the document for the battery profiling. Keep in mind that you will need a source meter, a voltage meter and a shunt resistor with the tool.

Please let me know if you have any follow up questions on the procedure you should follow. If you found any comment useful, please mark it as “accepted”.

Thanks, PM_Dialog
