The circuit of Figure 1 protects a lead-acid battery by disconnecting its load in the presence of excessive current (more than 5A), or a low terminal voltage indicating excessive discharge (< 10.5V). The battery and load are connected by a 0.025Ω current-sense resistor (R1) and p-channel power MOSFET (T1).
A perfect 12v battery discharger protection will cutoff just now to extend battery life and avoid sulfation, but the minimum is 10.5v (from the specs of the 12v battery).Our homemade protection circuit will stop the light at 10.8V so is perfect if we want to stay safe and we can proudly say that this solar charger is working properly.
The lead–acid battery was invented in 1859 by French physicist Gaston Planté and is the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio. We can see that is working as it should we can protect your 12v lead acid battery easy.
When the battery is recharged to a second predetermined higher voltage (upper voltage threshold), the relay contact automatically re-closes and power again flows to the load. Both lower and upper voltage thresholds are independently adjustable to the desired voltages.
Each cell provides 2.1 volts for a total of 12.6 volts at full charge.Each cell of a lead storage battery consists of alternate plates of lead (cathode) and lead coated with lead dioxide (anode) immersed in an electrolyte of sulfuric acid solution. The actual standard cell potential is obtained from the standard reduction potentials.
Although, overcharging a battery may be detrimental to a battery health and appropriate measures must be incorporated, an over discharge or a deep discharge can be also equally dangerous for a battery's health.
