Will Electric Vehicle Lithium Batteries Be Scrapped If Not Used For A Long Time?

If the battery is not charged for half a year, it will discharge. If it is queued for a month, it will basically be scrapped, but it can be repaired. There may also be a situation where it cannot be repaired and the battery must be replaced with a new one.

1. Series method. Another 12 volt battery with normal voltage is connected in series across the battery. For example, the original car has a 48V-20AH battery, then we connect a 12V-20AH battery in series. A fully charged 12V battery has a voltage of approximately 13V. After connecting in series, the voltage of the entire battery can be increased, and then charged with its original charger. In this case, charging is possible. After plugging in, the charger will turn red and it can be charged. When the charger turns green, simply remove the other battery in series. Then charge normally.

2. Parallel connection. This method is a little more troublesome. For example, the vehicle originally had a 48V-20AH battery, and we connected another set of 48V-20AH batteries in parallel. As we all know, the voltage in a parallel circuit is equal everywhere, and the high voltage end will flow into the low voltage end. This method is also used by many battery dealers to detect batteries that are not charged at all. Then charging can also achieve the purpose of charging. This principle is similar to that of batteries connected in series. It is also to increase the voltage of the entire group and connect a group of batteries of the same type in parallel.

3. Low voltage charging method. Choose a smaller charger for charging. For example, if we have a set of 60V-20AH batteries, we use a 48V-20AH charger to charge them. In most cases, this can also be filled in. The principle is similar to the first one, the charging voltage is closer to the voltage across the battery.

4. Single battery charging method. Charging a single battery with a 12-volt motorcycle charger can activate the battery, 54 but this charging is relatively slow. It usually takes more than 7 hours for the battery voltage to slowly rise to about 12 V. It is time-consuming to charge all single batteries.

5. Special charger method. Tianneng charger can automatically identify the battery voltage. No matter how many volts the battery has, it automatically recognizes the voltage and can charge it. For example, the original car had a 60V-20AH battery, but now it is less than 30V, and it can still be charged inside. As the voltage rises, it fully adapts to the higher voltage and then charges the battery.
