13. Main & Sub battery monitor

Entry:2019.07.08 / Work:2013.08.17

Using a general-purpose digital voltmeter, the panel was cut from an aluminum plate, and the surface of the plate was painted with a stone-like spray to match the atmosphere of the dashboard.
Press the red button to display the main & sub voltages separately. When the white toggle button is pressed, both batteries are connected. (for charging both at the same time by a charger when the main key off)

Photos & Working

A view from below with the panel fixed under the dashboard.

Display and button operation test.

A terminal was provided to connect multiple wires.

The panel cuts the aluminum plate, opens a hole, and adjusts the shape.

Since the main battery is on the right, the sub battery is set in the same position on the left.

Install a relay circuit that connects the main and sub-batteries when the key is turned on and charges the vehicle while driving.
