If a charger is connected and the battery pack is isolated from the charger, the current injected towards the battery pack will cause the voltage to rise to the charger’s maximum supply voltage. The voltage level at CHMON is tripped letting the BMS device know a charger is present.
It provides a detailed diagram that helps in understanding the design and functioning of the charger. The schematic shows the flow of current and voltage through various components, enabling engineers and technicians to analyze and troubleshoot the circuit.
The battery pack can be balanced on the discharge cycle by implementing a charge displacement scheme. A charge displacement scheme is achieved by taking charge via inductive coupling or capacitive storage from the alpha cell and injecting the stored charge into the weakest cell.
A charging scheme as described does not maximize the battery pack ON time per charge. The charging scheme also reduces the lifetime of the battery pack because more charge and discharge cycles are needed. A weaker cell discharges faster. The same type of occurrence happens on the discharge cycle.
For example, Intersil’s ISL94203 standalone battery pack monitor has a CHMON input that monitors the voltage on the right side of the cutoff FETs. If a charger is connected and the battery pack is isolated from the charger, the current injected towards the battery pack will cause the voltage to rise to the charger’s maximum supply voltage.
The electrical path to pull up the battery pack VCC passes through the host capacitance from Pack+ to Pack–, through a substrate diode in the host interface driver from VSS to the commu-nication or interface line, and through a substrate diode from this line to VCC in the battery-pack circuitry. The complete path is shown in Fig. 6.

These schematics are particularly useful for designing and building custom battery chargers for specific applications. They allow engineers to choose the appropriate components, such as resistors, diodes, capacitors, and transistors, based on the desired charging characteristics and requirements of the battery.
Monitor Temperature: Ensure that the charging environment is not too hot or cold. The ideal temperature range for charging Li-ion batteries is between 10°C and 30°C (50°F and 86°F). Partial Charging Cycles: For regular use, adopting a partial charging cycle (e.g., charging to 80% and discharging to 20%) can help extend the battery''s lifespan.
