Another option, particularly for high voltage circuits, is to use a pre-charge circuit.
2.
:If it happened all at once, I'd suspect some portion of the charging circuit is bad.
3.
Since this method measures the voltage across the battery, a constant current ( rather than a constant voltage ) charging circuit is used.
4.
To detect all conditions of overcharge demands great sophistication from the charging circuit and a cheap charger will eventually damage even the best quality cells.
5.
The charging battery load is not treated as a " base resistance " though, as the charging circuit can be turned off at any time.
6.
Normal operation of a pre-charge circuit is to terminate pre-charge mode when the circuit voltage is 90 % or 95 % of the operating voltage.
7.
The power which the car privides is very near the voltage which the phone needs to charge, the car chargers provide only a charging circuit and a voltage regulator.
8.
That'll let you know whether you just have insufficient charge, whether one or more cells has died or whether the battery charging circuit inside the scooter has failed.
9.
At the end of the day it was " check your charging circuit first-then the terminal voltage of the'whatever "'rather than the other way around.
10.
The VOOC Flash Charge circuit technology reportedly lowers the temperature of the charging adapter, and creates an interface from the adapter to the phone, which improves the speed and safety of the charge.
