　　Many people are riding electric bicycles. This is a practical, simple and easy-to-operate means of transportation. It is no exaggeration to say that anyone who can ride a bicycle can easily learn to ride an electric bicycle. But how to maintain an electric bicycle? How to better maintain electric vehicle batteries? Some car owners may not have ridden an electric bicycle for a long time. If they want to use it again, they find that the battery is no longer used. The lithium battery has not been charged for a long time. How to activate the battery?

　　There are currently two types of lithium-ion batteries commonly used on the market, lithium manganese oxide 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. Generally around 5%-10%, lithium-ion batteries can be stored for 1-2 months without charging. However, this does not mean that lithium-ion batteries cannot be charged for so long. The proposed storage method requires charging at intervals even if it is not used for a long time.

　　How to activate a lithium battery that has not been used for a long time:

　　1: Rechargeable batteries in series increase the working voltage, first connect to all ordinary 12V rechargeable batteries, such as 48v/20a rechargeable batteries, and then connect to a series of 12V rechargeable batteries, the working voltage can slightly go up and down to 13v, and then connect to the main charger The head can be charged, wait for the light to turn green charging head, after the series charging battery is removed, all ordinary batteries can be charged.

　　2: Parallel battery conversion, one series rechargeable battery is connected to a rechargeable battery of the same specification, such as 48v/20a rechargeable battery, and one is connected in series to a group of normal rechargeable batteries. At this time, the operating voltage will flow into a low-voltage rechargeable battery to recharge the battery. After charging, the battery can be connected to the charging head.

　　3: Low-voltage battery charging. If the lithium-ion battery has no battery charge for a long time, it can first use a small low-voltage charging head for slow battery charging, such as a 60v/20a rechargeable battery, and then charge the 48v/20a small battery, which can also be charged.

　　According to the above method, the purpose of activating "starved" lithium batteries can be achieved. If the above method is difficult to achieve, or the professional brand repair shop must be repaired immediately. In addition to hot summer and high temperature weather, the battery charger should also be used. Be careful not to expose the battery to heat in hot weather. If the battery capacity is too low, charge it immediately. Lithium should be used at any time to maintain a shallow circulation system for a longer period of time.
