Can the tdt515z battery of Xiaoling electric vehicle be replaced with a lithium battery?

No. According to article 18 of the Regulations on the management of electric bicycles: If your home is equipped with an electric bicycle with a lead acid battery and there is a problem with the battery and needs to be replaced, you must contact the manufacturer to replace the lead acid battery. of the same model or similar, instead of going directly to the store to replace it. At the same time, operating stores cannot replace lead-acid batteries with lithium batteries for consumers without authorization. Therefore, the tdt515z battery of Xiaoling electric vehicle cannot be replaced with lithium batteries.

After the lead-acid battery of an electric bicycle fails, is it possible to replace it with a lithium battery?

Lithium batteries are widely used as new sources of energy, non-polluting and consistent with national industrial policies. Suitable for electric bikes, hasux electric tricycles, electric motorcycles, automobile emergency power supplies, solar and wind power generation and storage devices, etc. But generally, newly purchased electric vehicle lithium batteries need to be assembled. So how do you assemble lithium batteries for electric vehicles? The technical staff of Asialand aluminum battery case manufacturer will explain it to you below:

Step 1: Inspection

During the battery disassembly process, check the quality of all connections. At the same time, check whether the safety bracket, charging socket and connection wire contact of the electric vehicle lithium battery are normal and reliable, and tighten all connections. Those that need to be replaced need to be replaced, and their reliability should be focused on those that are unreliable.

Step 2: Installation

The battery in theithium of the electric vehicle must be installed according to the instructions contained in the battery case. In fact, most batteries inside the battery box are connected in series. Each battery is connected in series with a copper wire of at least one square meter and soldered with a soldering iron. Finally, there are two output terminals, positive and. negative, soldered on both sections of the output jack, be careful not to connect them backwards, and they must match the positive and negative poles of the charger. Otherwise the consequences will be serious.

Step 3: Testing

After installing the electric vehicle lithium battery, use a multimeter to measure the voltage of the battery output port. The actual battery voltage is slightly 2 higher than the standard voltage. ~5V. It can be put into normal operation after normal operation.

Theoretically, it is possible, but the tensioncharging cut-off voltage of the charger and the discharge cut-off voltage of the electric vehicle need to be adjusted.

Lead-acid battery cells (2V platform) typically have a charge cutoff voltage of 2.35V and a discharge cutoff voltage of 1.6V

So the theoretical charging cut-off voltage- The cut-off voltage of a lead-acid battery module is 48 V. It is 56.4 V (usually the manufacturer's setting is 55 to 56). The discharge cut-off voltage will be 38.4V and the actual setting value is the lowest around 39V. >

The general charging voltage of lithium manganate monomer (3.7V platform) is of 4.2 V, the discharge cut-off voltage is 2.6 V

So, in theory, the charge cut-off voltage of a 48 V The lithium manganate battery module (in makes 51.8V) is 58.8V, which is higher than the set value of the charger, which will cause the problem of insufficient charging. The tenDischarge cutoff voltage is 36.4V, which is much lower than the currently set minimum value, so it can be used directly. Lithium-manganese oxide batteries are therefore mainly equipped with suitable chargers. There is no need to tune the motorcycle, but the battery capacity will be used and not recharged. points, but it can also extend the battery life.

Lithium iron phosphate batteries (3.2V platform) typically have a charge cutoff voltage of 3.7V and a discharge cutoff voltage of 2.0V (which is the battery lithium iron BYD is cheating, and some manufacturers are cheating rare earth iron-lithium batteries (this is a concept

Make a pair of 48V modules (15 strings), the charging voltage). is 55.5V, the discharge cut-off voltage is 30V, it can basically be used normally without adjusting the charger and the motorcycle.ter that many lithium iron batteries are nominally 48V, but their actual platform voltage is 51.2V (16 string). In this case, the charger must also be replaced.

In theory, lithium manganate can be charged and discharged 500 times, and its lifespan is approximately just over a year. Lithium iron phosphate can be charged and discharged 2,000 times and can be used for 3 years. In terms of price, the price of lithium manganate can be less than 1,000, and the price of lithium iron phosphate battery is higher.
