Diversion of Excess Power Example (Cell Voltage Max Trigger)

A wind turbine is used to generate power and charge the battery. To prevent the battery from overcharging, a relay is set up to activate when the battery cell voltage is nearing its maximum level and uses power in the battery to heat water in an electric hot water tank.

Activated: 1 second after the battery cell voltage rises above 3550 mV

Deactivated: 1 second after the battery cell voltage drops below 3400 mV

Once the switch (pin 6) is closed (activated), the battery powers the electric hot water tank until the battery cell voltage drops below 3.4 V for 5 minutes. In this system, the gas hot water tank is the main source of hot water, and the electric hot water tank is for preheating the water for use in the gas hot water tank.

Energy generated from the wind turbine either charges the battery or heats up the water. No energy is wasted in this system.
