The electric car headlights were stolen by the thief. After changing the headlights, I wanted to be able to go back to the original, but I didn’t want to make a mistake. The battery was also damaged for a long time. The cruising range was only a few, and now I have to replace the battery. How will the following things develop? Please listen to me slowly.
After the lead-acid battery was broken, I wanted to change a lead-acid battery, but from the Internet, many users of lead-acid electric vehicles have changed their lithium batteries.
Under the trend of curiosity, I began to study lead acid and lithium battery, and consulted experts in this field. In the case of ensuring foolproof, I found a teacher with many years of maintenance experience to replace.
Lead-acid battery for lithium battery mainly pay attention to the following points
First, the battery space problem
The same capacity voltage replacement of lead-acid batteries and lithium batteries is feasible, but it is necessary to consider whether the size of the battery can be installed in the original position, whether it is protruding or squeezed, because the internal damage of the battery occurs due to squeezing and moisture. Short circuit phenomenon.
Second, you must use a charger that matches the type of battery
The lead-acid battery and the lithium battery have the same capacity voltage, and the charger is used indiscriminately, because the charging voltage and current of each stage required by the two batteries are not equal. When the lead-acid battery is charged, the charger voltage is high. The lithium battery technology requires higher, so charging When the charger is used for constant voltage constant voltage charging, lead-acid rechargeable lithium battery will cause overshoot, there is a danger of explosion.
Third, socket replacement
Because the interface between the lead-acid battery and the lithium battery is different, it is necessary to use a matching socket to change the battery. Do not plug it in, which may cause a short circuit of the lithium battery, which may cause danger.
4. After replacing the battery, you cannot use the original charging port to charge.
Because of the different charging principle, if the original charging port on the electric vehicle is used for charging, the circuit will be damaged and the lithium battery will be short-circuited.
Five, after replacing the battery, the controller does not need to be replaced
It is also important to mention here that replacing the battery can only replace the same voltage of the same capacity, and can not be replaced with the previous battery capacity voltage, which will burn out the controller and damage the electronic components such as the motor Hall. As long as it is the original battery capacity If the voltage matches, there is no need to replace the controller.
