Precautions for replacing lithium batteries with electric bicycles using lead-acid batteries

Lithium batteries are a major trend in the future, so can the original lead-acid batteries of electric vehicles be replaced with lithium batteries, and what issues should be paid attention to when replacing lithium batteries? The following is an explanation of the lithium battery manufacturers of electric bicycles. Precautions for replacing lithium batteries with lead-acid batteries for electric bicycles 1) First of all, to convert lead-acid batteries to lithium batteries, we need to replace the charger with a charger that matches the lithium battery, the charging method of the lead-acid battery charger and the charging method of the lithium battery It is completely different. For example, lead-acid batteries use high-frequency pulse charging. After reaching the stop charging standard, they will switch to a small current and continue to charge for a certain period of time. Some lead-acid battery chargers will still have a small current after the battery is fully charged. Charge the battery. This is not in line with the charging characteristics of lithium batteries. The lithium battery charger uses CC/CV constant voltage and constant current charging. When the set stop charging conditions are reached, the current will be cut off directly. After the lithium battery charger stops charging, there is no current. Continue to output. So the two cannot be mixed. Someone may ask here, don’t all lithium batteries have a protection board to protect them from overcharging? Wouldn't it be protected if overcharged? It needs to be explained here that there is a certain numerical difference between the overcharge protection and the charger stop charging settings. The overcharge protection of the protection board is passively triggered, when the lithium battery protection board triggers the protection. The lithium battery itself has been overcharged. This is very harmful to lithium batteries. 2) The battery needs to be matched. There are skills when matching the battery. The fully charged state of a 48V lead-acid battery is 55.2V. There are 4 types of 48V lithium batteries, 13 strings of 54.6V and 14 strings of 58.8V, Lithium iron phosphate has 15 series of 54V and 16 series of 57.6V, these specifications can be matched with the original 48V lead-acid battery electric vehicle. The electronic parts of lead-acid batteries and electric vehicles all have a wider withstand voltage value, and the voltage slightly higher than that of the original battery can withstand. The conventional battery on the market is a 13-string lithium battery. In fact, if you choose a 14-string lithium battery for electric vehicles, the performance will be better. It should be noted here that some brands of electric vehicles will control the controller, so before changing the battery, you need to do a test. 3) Regarding the capacity, the maximum capacity value does not need to be considered, but the minimum capacity needs to be matched according to the power of the electric vehicle motor. Too small capacity will often cause battery fatigue. 4) After an electric vehicle hits a lithium battery, the battery compartment of the original lead-acid battery will be larger, which may cause the newly installed lithium battery to shake in the battery compartment. This is not allowed. After the lithium battery is installed, the lithium battery must be fixed. , There must be no shaking, and a seismic structure needs to be done. 5) It is very necessary to choose formal production of lithium batteries. Shenzhen Electronics Co., Ltd. is a professional power lithium battery PACK manufacturer, professional electric bicycle power lithium battery. Power tool battery. In short, there are no too complicated technical requirements for changing lead-acid batteries to lithium batteries for electric vehicles. We only need to pay attention to the charger to be replaced, the lithium battery needs to be matched, fixed installation does not shake, and the battery must have a seismic structure.
