What are the precautions for replacing lead-acid batteries in electric vehicles with lithium-ion batteries? How to replace your own lead-acid batteries with lithium-ion batteries? Is it okay to replace only the batteries? The answer is of course no. Now, let's take a look at how to turn a lead-acid battery electric car into a lithium-ion battery. Can lead-acid battery electric vehicles replace lithium-ion batteries? It can be changed, but it is not recommended. The following is a detailed introduction: Lithium-ion batteries for electric vehicles. JPG1. We all know that after the introduction of the new national standards, the standards for electric vehicles have been strictly regulated, which means that the testing of electric vehicles will be more stringent. On the other hand, the company must also have 3C certification and electric motorcycle qualification. Generally speaking, if they replace lead-acid batteries with lithium-ion batteries, they may face the risk of not being able to go on the road; 2. If lead-acid batteries replace lithium-ion batteries, they must also consider that the voltage must remain the same as the original lead-acid batteries In addition, the charger will also replace the dedicated lithium-ion battery charger. Of course, there is a problem. If the lithium-ion battery is improperly installed or has any quality problems, the controller may be burned out. This is one of the reasons why it is not recommended to install; 3. In addition, lead-acid batteries replace lithium-ion batteries, and the size of the battery must also be considered. Generally, the lead-acid battery compartment is relatively large, and the volume of the lithium-ion battery is relatively small. If you want to change, you must consider this factor. Too big, it is easy to cause vibration in small batteries after installation, reducing life; 4. Compared with lead-acid batteries, the stability of lithium-ion batteries is poor. In case of water or improper operation, it is prone to explosion hazard. One more thing to note is that lithium-ion batteries have a multi-chip structure, and any problems will affect the overall quality. What are the precautions for replacing lead-acid batteries in electric vehicles with lithium-ion batteries? Volume 1, modification time, to consider the issue of space, at the same capacity, the volume of lithium-ion batteries is only half of that of lead-acid batteries, so of course it is possible, but it must Pay attention to some shape and packaging issues. After all, the car space may not just be the battery in one direction. You have to consider fixing and reliable to prevent the vibration from falling. In the case of economic conditions permitting, of course, it is hoped that the capacity of the modified lithium-ion battery is as large as possible. Therefore, it is necessary to make full use of the upper space and choose a battery with a reasonable shape to arrange it. If the lithium-ion battery of the same capacity is replaced, because the remaining space is too large, we have to find something to fill the excess space when replacing it to prevent the lithium-ion battery from falling off while driving. Remove the battery, the battery output is positive and negative in two lines, it is very simple, but it should also be detailed, wrapped in tape, bare wires, and then pay attention to the positive and negative signs, so install it back, again, the negative and negative details to prevent positive and negative while working Negative haze connection backwards, or inadvertently short-circuiting the positive and negative poles of the battery is a negative contact causing safety issues. 3. When buying lithium-ion batteries, it is best to have the same or similar plug terminals. If the shape of the plug is different, some people may have to re-crimp the ears or solder, or even want to connect the wires. It is important to pay attention. It is best to measure the voltage with a multimeter and DC connection time to prevent negative reversal. Remember, anode and cathode must be placed separately, do not perform operations like anode iron. 4. If the battery is changed and the motor and controller are also added, it is necessary to consider whether the important return route should also be bold. You can check the electrician manual to see how many square wires can pass and how many amperes of current. The original car line is very thin, which will leave a safety hazard, and the efficiency and power effect will be reduced. 5. Lead-acid batteries, lithium-ion batteries, chargers must be changed to special lithium-ion batteries, lead-acid batteries have large internal resistance, the highest output voltage of general chargers, and a large number of pulse charging functions, so she may overcharge Li-ion battery charging time, because of the protection of the protection board, the charging time will cause the charger output voltage to be set to be abnormal, and the backward progress of the monomer may cause uniform filling and cause damage. If the protection board is accidentally damaged, high-voltage charging can easily cause a short circuit.
