How to activate the lithium battery of an electric vehicle when there is a low voltage and cannot be charged normally

Many people are riding electric bicycles. This kind of practical, simple and easy-to-operate means of transportation can be easily learned by anyone who can ride a bicycle. Riding an electric bicycle is easy to learn, but how to maintain an electric bicycle? How to better maintain electric vehicle batteries? If you haven't been riding an electric bike for a long time, when you use it again, you find that the battery won't work. Then the lithium battery of electric vehicle has not been charged for a long time, how to activate the battery? There are two types of lithium-ion batteries commonly used in the market, lithium manganate batteries and lithium iron phosphate batteries. If these two types of batteries are not in use, they must be stored scientifically. Lithium-ion batteries have a certain self-discharge rate. It is generally around 5%-10% at room temperature. Lithium-ion batteries can be stored for 1-2 months without charging. However, this does not mean that lithium-ion batteries can not be charged for so long. The proposed storage method is to charge it at intervals even if it is not used for a long time. However, if there is a specific low temperature environment, the storage time of lithium batteries can also be extended. How to activate the lithium battery of an electric vehicle when there is a low voltage that cannot be charged normally: Method 1) Connect the first voltage battery, and gradually increase the battery voltage slowly. For example, when the 48V battery is over-discharged below 30V or lower, it may not be possible to complete the normal charging. Use a 36V or 24V battery charger to charge the battery first. Method 2) Connect the batteries in parallel to forcibly trigger the charger to charge the batteries. Pay close attention to the status of the batteries. According to the above method, the over-discharged lithium battery can basically be rescued. If the method is difficult to achieve, the lithium battery of the electric vehicle needs to be repaired. During use, the lithium should be charged at any time, and there is no need to wait until the battery is completely discharged. , Lithium batteries maintain a shallower cycle and have a longer lifespan.
