The primary function of these circuits is to ensure the rechargeable battery never overcharges or drains too low. If a lithium battery is left to self discharge to 0% SOC and remains in storage allowing the protection circuit to further deplete the cells, this often results in a damaged or unusable battery (unhappy customer). This means, that the ECUs (Electronic Control Unit) have to be protected against reverse battery polarity. The cells selected by us have a nominal voltage of 3.7Volts while the charge voltage is 4.2V. 0.29 A ). As given in the circuit above, the switch can be driven by the PWM-oscillator, such that the power delivered to the step-down transformer is controlled indirectly, & hence, the output is controlled by the pulse-width-modulation, as this Learn how to make batteries safe with built-in protection circuits. Further layers of safeguards can include solid-state switches in a circuit that is attached to the battery pack to measure current and voltage and disconnect the circuit if the values are too high. Protection circuits for Li-ion packs are mandatory.
