I have a requirement that might involve a PICO-W to control charging of a 12V leisure battery.
Overview of what I am trying to achieve, I have bought an automated lawnmower which has a docking station that connects to a 240v power supply and delivers 20V DC to charge the lawnmower. As I do not have an external 240v socket but have solar panels and spare leisure batteries I thought I could use these.
Solution, I have a solar charge regulator that charges the 12v battery the solar panel output is approximately 20v and this is charging the battery. I have ordered a step-up power regulator that will convert the 12v battery power to the required 20v power that the lawnmower needs.
Problem, I am guessing that I should not charge and use the 12V battery simultaneously as the charge regulator will not be able to establish the correct charge.
Thoughts, if simultaneous usage is not possible could I use a PICO-W to solar charge the battery during the day and overnight switch the battery to charge the lawnmower overnight? If this is an option what would be my best option for PICO-W switch?
Another way that I am considering is to buy some form of regulator and connect the solar panel directly to the lawnmower. The regulator needs to restrict/control the output voltage to 20V, the challenge I see is the solar panel outputs a range of below and above the required 20v so step-up or step-down is not an option
