Ni-MH battery packs

　　Common problems in the application process of Ni-MH battery packs for electric vehicles

　　There are many common problems in the application process of Ni-MH battery packs for electric vehicles:

　　First, lithium-ion batteries cannot be charged with lithium for several reasons: charging head or charging head failure; lithium-ion battery protection board maintenance or lithium-ion battery protection board failure; short-circuit failure of lithium-ion battery packs and high-power electrical appliances.

　　The memory of the rechargeable battery is the reversible effect of the rechargeable battery, that is, the effect that the rechargeable battery can be repaired again after failure. Generally lead-acid batteries have memory, lithium does not. Therefore, lithium-ion batteries do not need to be recharged after being discharged. This is to extend the service life of lead-acid batteries, while for lithium-ion batteries it is to reduce the service life.

　　This situation is due to the lithium-ion single string charging or volume inconsistency, which is first filled with high or low capacity, and other series of rechargeable batteries cannot be filled with the entire charging process due to the maintenance force of the lithium-ion battery protection board. The battery can reduce the size and weight of the system, allowing for more reasonable use of space. The long-life design of the lithium-ion battery will greatly reduce costs and maintenance pressure.

　　Second, does the lithium battery need to be activated?

　　Today, battery charging points for electric vehicles are in many garages in residential areas. For rural customers, they can choose a naturally ventilated, waterproof, rainproof, cool and dry address to charge the battery according to home conditions.

　　Lithium is naturally necessary, but this process is not your actual operation. It is activated before the original factory leaves the factory. The whole process is a capacity-dividing process. The rechargeable batteries arriving at the customer are already the same volume and can be used immediately. However, in some cases, it takes more than half a year for the lithium-ion battery to reach the customer, and the level is likely to have passivation treatment, so a 2-3 battery charging cycle system is used to make the lithium-ion battery work before application.

　　For the sake of landing, most charging heads today do not have a high anti-vibration design, so the charging head generally does not need to be placed in the trunk of an electric car or a car basket.

　　3. For new rechargeable batteries, the first three must be charged for 12 hours?

　　The nickel-metal hydride rechargeable battery on the original box phone must be charged for 12 hours for the first three times, because the nickel-metal hydride rechargeable battery is memoryable, so it needs to be kept charged, but the lithium battery has no memory, so it is not needed.
