Firstly, Hi Everyone.
I am totally new to this amazing site and look forward to trying to be part of the community.
So with the above in mind, I would like to ask for some help with a project please.
I have VERY little experience within this field but am a quick study so please bear with me if I don't use technical descriptors and jargon.
I have a dashcam in my vehicle that is powered from a purpose designed battery. This enables me to park for several days and still have my dashcam active without discharging my vehicle battery.
My problem is that by the time I go to use my car, the battery running my dashcam is invariably flat. This means that my dashcam wont power on until I have been driving sufficiently to charge the dashcam battery. This can take up to 10 minutes.
I would like to design a circuit that will sit in between the Dashcam and the dashcam battery that allows the following to occur:
On switching on the ignition, the dashcam is powered from a switched ignition source of between 11 - 15VDC. Upon the dashcam battery reaching a sufficient charge (12VDC) the circuit will auto switch to the dashcam battery input.
When the vehicle is switched off the dashcam will draw power from the dashcam battery until it reaches a critical level and then will disconect. It will then auto reset ready for when the ignition is switched back on again to repeat the process (if required as the dashcam battery may NOT be flat).
The switching between both sources would need to be seamless and appear to the dashcam to be uninterupted as it would switch itself off and back on therby interupting recording.
Long winded I know but I presume it would be feasible and would anybody be able to steer me in the right direction (whilst remembering my knowledge level).
Any help would be gratefully received.
Regards,
Simon
