When a 48 volt lithium iron battery is charging, the actual input voltage is higherthan the rated voltage, between 48 volts and 55 volts, so the 48-48 volt lithium iron battery The voltage of the battery after being fully charged is in the normal range between 48 volts and 55 volts, and the maximum voltage is 55 volts if it exceeds 55 volts , the 48 volt lithium iron battery may be damaged.
It is best to charge for a slightly longer time for the first time, usually 8-12 hours. Because the battery has a renewal process from leaving the factory to being installed in the car and then into our hands, during the renewal period, the battery will have insufficient capacity due to discharge, so it must be charged with a charger until sufficient. .
Prevent the plug from getting hotwhile charging
A loose 220 volt power plug or charger output plug, oxidation of the contact surface, etc. will cause the plug to overheat. Heating time is too long, it will cause short circuit or plug contact. If it is defective, it will not only damage the charger but also the battery. It is therefore necessary to prevent the charger plug from heating up when charging and to quickly remove oxides or replace the connector.
It is necessary to partially discharge the lithium-ion battery of electric vehicles and avoid frequent full discharge. Over-discharge can have catastrophic consequences for the battery, or repeated over-discharge can have a particularly severe impact on the battery.
What is the continuous current of the 48V2A lithium battery charger?
Approximately 58 volts.
The rated voltage is 48V and the rated current is 20A. Through calculation, we can know that in the theoretical state, the discharge capacity of the 48V 20Ah battery is 0 .96 degrees (rated voltage*). rated current * time = 48 V * 20 A * 1 h).
In addition, since the actual charging efficiency cannot reach 100%, only 90% to 95%, generally speaking, the actual charging capacity is 1.05 times the discharge capacity, so we can get the actual charging capacity to be about 1 kilowatt hour (0.96 degrees*1.05). In other words, 48V20Ah only requires 1 kilowatt hour of electricity from no power to full power.
Precautions for charging 48 volt lithium batteries
When charging, first connect the battery, then turn on the power. After fully charging, first disconnect the power, then disconnect the battery and charger. Keep the key coverclosed when connecting the battery to the vehicle.
Overcharge danger: Unplug the charger in time after full charging, and do not charge continuously for more than 8 hours.
Do not charge in sub-zero temperature environments. When charging, you must use a dedicated lithium battery charger. Roadside fast charging is not permitted. 48, 60 and 72 volt chargers cannot be mixed.
The output voltage of 48V electric bike charger is 55~59.6V and the output current is 2.1~3A. 48V charger, the voltage the highest is not more than 59.6V. If the voltage is higher than this, the light may not turn on when charging. Low voltage is not less than 55V. If the voltage is lower than this, it will cause. insufficient charge and the battery will easily lose power for a long time, 48V charger, the maximum current does notdoes not exceed 3A. More than 3A may cause the battery to lose water sooner, and the minimum is not less than 2.1A. This low voltage current causes insufficient charging.
The output voltage of the 48V electric bike charger is 55-59.6V and the output current is 2.1-3A. 48V charger, the highest voltage n 'is not higher than 59.6 V. If the voltage is higher than this, the light may not turn on when charging. Low voltage not lower than this voltage will result in insufficient charging. the battery will easily lose power for a long time; current, 48V charger, the maximum current does not exceed 3A. More than 3A may cause the battery to lose water sooner, and the minimum is not less than 2.1A. This current at low voltage causes insufficient charging.
