    The battery is 72 volts, and now it is only 24 volts, and it cannot be charged, which indicates that some of the batteries in the electromagnetic group must have been short-circuited. And most of the batteries have been short-circuited, so it is better to replace them as a whole, otherwise, part of them will be replaced, but the part that has not been replaced has been used for a long time, and the whole is not cost-effective.

    With a new battery, it will be fully charged in 4 hours, which is indeed a bit fast, unless you use a high-current fast-charging charger.

    If it is an old battery, it is relatively normal for 4 hours, especially if it is used, and the battery that has been in the past year has been in the letter. Because the battery is depleted, when you use it for a year, it will take almost 4 hours with the electrical damage.

    The new battery, the normal should be 7 to 8 hours to charge, it may be that your battery has more power and start charging.

    The 72-volt 32-ampere maintenance-free lead-acid battery is fully charged in 4 hours, which does not necessarily mean that there is a problem with the battery. According to my experience in use and maintenance, it may be that the battery is not short of power, so the replenishment charging time will not be too long. Another possibility is that the battery has been used for more than 2 years, the internal resistance becomes larger, or the battery is short of water, which may occur.

    It is recommended that you can go to the electric vehicle sales point and ask the master to test the electricity consumption test instrument.

    Summary. Hello, 1.In the use of lithium batteries, it should be noted that the battery will go into a dormant state after a period of time.

    2.Self-discharge will deplete the battery, and the capacity will be lower than normal, causing the battery to be too low to charge. 3.

    But the lithium battery is easy to activate, as long as it goes through 3-5 normal charge-discharge cycles, the battery can be activated and the normal capacity can be restored. 4.Due to the characteristics of the lithium battery itself, it is determined that the lithium battery has almost no memory effect, so the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process.

    Hello, 1.In the use of lithium batteries, it should be noted that the battery will enter a dormant state after being placed for a period of time. 2.

    Self-discharge will deplete the battery, and the capacity will be lower than normal, causing the battery to be too low to charge. 3.However, the lithium battery is easy to activate, as long as it goes through 3-5 normal charge-discharge cycles, it can activate the Dianzhou pool and restore the normal capacity.

    4.Due to the characteristics of the lithium battery itself, it is determined that the lithium battery has almost no memory effect, so the new lithium battery in the user's mobile phone does not need special methods and equipment in the activation process.

    If it can't be charged into the grinding electricity, there are only several situations: 1. The lithium battery is in an over-discharge state That is to say, the lithium battery is discharged very low, in a deep discharge state, and the power is basically used up, so that it is as low as the cut-off voltage of the lithium battery, at this time, the activation method can be taken, but this is not necessarily effective; 2. There is a problem with the charger or charging line First of all, you should check whether there is a problem with the charger, the method is very simple, directly measure the output voltage or connect the load of the corresponding voltage to observe, as for the problem of the line, and orange bucket then it will take a little effort, after all, it involves circuit hardware and other problems, if necessary, directly disassemble and analyze; 3. The lithium battery has been used for a long time, and the battery has failed The possibility of this happening is relatively small, but it cannot be ruled out that your own battery should be familiar with it, and the battery should be replaced after how long it has been used; 4. Problems with the battery charging IC or BMS system Problems with the battery management system due to the imbalance of the battery cells and other reasons, resulting in misjudgment of the management IC and the failure to detect the voltage or current.

    1) Battery charger problem 1) Charger failure, that is, after using it for a period of time, the charger is damaged due to failure, and the charger cannot be charged normally. In this case, it is advisable to replace the charger. 2) The charger does not match, it may be that the current and voltage of the charger** are too low to charge the battery; Or the voltage is too high and the current is too high, so that the battery is damaged when charging, resulting in the inability to charge.

    2) Environmental factors affect battery charging: 1) The charging environment temperature is too low. The 18650 battery has a low-temperature charge-discharge limit, which may be due to the low ambient temperature of the charging environment, resulting in charging failure. This allows the battery to be charged within its specified charging temperature range, which is generally possible.

    If not, it is estimated that the battery has been used at too low temperature for too long, causing problems with the battery. So we have to replace the battery. 2) The charging environment temperature is too high, the general 18650 battery temperature protection mechanism, can be caused by high temperature protection, resulting in the inability to charge, the battery can be allowed to charge the temperature range, if not, maybe because the battery is operating at high temperature, resulting in a short circuit battery or other chemical reactions that cause the separator to rupture, resulting in the battery can not be used.

    We have to change the battery.

    Summary. The output voltage of the charger is generally between 115% and 123% of the nominal voltage of the battery. For a 48-volt charger, the maximum output upper limit voltage is volts, and if it exceeds this voltage, it will always be charged with a red light; The minimum output voltage should not be lower than 55 volts, and it will not be lower than 53 volts in the limit state, otherwise it will cause insufficient power to charge and damage the battery, if the battery itself is ruled out, the output of your charger is only 42 volts when charging, which means that the charger is broken.

    The charger is 48 volts without plugging in the battery, and only the output voltage is only 16 volts.

    Abnormal, the voltage is too high, the normal 12V battery is fully charged, the maximum 14V48V charger is not plugged in, and the output voltage is only 16V.

    The voltage is too high and broken.

    Is the charger broken?

    Which part of the charger is broken.

    The 48-volt charger has a green light that stays on, and the output voltage is only 16 volts.

    The output voltage of the charger is generally between 115% and 123% of the nominal voltage of the battery. For a 48-volt charger, the maximum output upper limit voltage is volts, and if it exceeds this voltage, it will always be charged with a red light; The minimum output voltage should not be lower than 55 volts, and it will not be lower than 53 volts in the limit state, otherwise it will cause insufficient power to charge and damage the battery, if the battery itself is ruled out, the output of your charger is only 42 volts when charging, which means that the charger is broken.

    It is not excluded that the voltage of the output voltage falls on the output circuit, such as poor contact at the joint, or the output line is aging, or some output components are broken, resulting in a voltage drop, you can disassemble and check to see if there is a color, there is a difference in taste, of course, you need to have hands-on ability, it is not recommended that individuals operate themselves in a live state.
