EDIT 28.06 Took some time to look for appropriate MOSFET and I believe I have found it. BACKGROUND. Voltage. which allows for ionic movement and two electrodes areconstituent In this electronics project, a zener diode based circuit will be designed to protect a battery from over discharging. When a battery is charged, its terminal voltage i.e. voltage between the anode and cathode of the battery increases. On full charging, the terminal voltage reaches a peak value which is an indication of 100 percent charging. Power storage, UPS, traffic signals, and remote applications use these batteries. 98. Therefore, apparatus without deep discharge protection can only be retrofitted if they are converted with relatively high outlay. 2. Batteries are typically made of six galvanic cells in a series circuit. Each cell provides 2.1 volts for a total of 12.6 volts at full charge.Ea Li-Ion Battery Undervoltage LockoutFigure 1 shows an ultralow power, precision undervoltage-lockout circuit. This current-limiter circuit is attached to the negative electrode, and then the current passes through a very thin conductive ribbon up the side of the can to the positive electrode (ribbon shown in I. When the alkaline batteries are deep discharged, they are prone to leaking. A good battery protection circuit will also provide over-discharge protection. It is used in the circuit to pass a current of up to 20 A and disconnect the load when the battery voltage falls below a preset threshold. Order) This is probably enough to prevent any electro-chemistry taking place. Apr 15, 2011 #6 Syncopator Full Member level 6. If battery voltage go down to 3.3 V the torch should cease operation. In order additionally to enable a disconnection of a load connected to the battery by the circuit configuration even when the final discharge condition is met, the circuit configuration requires at least three terminals.
