Many people are riding electric bikes, this practical and simple and easy to operate transportation, as long as you can ride a bicycle can easily learn to ride an electric bike is very simple to learn, but how to maintain the electric car? How to better maintain the electric car battery? If you don't ride an electric bike for a long time, when you use it again, you find that the battery can't be used. So how to activate the battery when the electric car lithium battery has not been charged for a long time?
There are two kinds of lithium-ion batteries commonly used in the market, lithium manganese acid batteries and lithium iron phosphate batteries, which must be stored scientifically if they are not used. Lithium-ion batteries have a certain self-discharge rate. At room temperature is 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 can be stored for so long without recharging. The proposed storage method is to recharge at intervals even if they are 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.
When the electric car lithium battery low voltage can not be charged properly should be how to activate.
Method 1) Link the first voltage battery, gradually and slowly raise the battery voltage in. For example, when a 48V battery is over-discharged below 30V or lower, there may be no way for normal charging to be completed. Using a 36V, or 24V battery charger can charge the battery first.
(Method 2) Parallel battery forced to trigger the charger to charge the battery, need to pay close attention to the state of the battery.
According to the above method can basically save the over-discharged lithium battery, if the method described is difficult to achieve, it is necessary to repair the electric car lithium battery, in the use of lithium should be charged with the use of the process, do not have to wait until completely dead and then charged, lithium batteries maintain a shallower cycle, but a longer life.
