Do electric vehicles slow down after passing through the speed bump
May 13, 2021

If you ride an electric car over the deceleration belt and do not wipe the car, there are the following situations,

① It is easy to cause the frame to fall apart.

② Deformation of tire and motor.

③ The car shell is loose, causing the car shell to fall apart.

For safety reasons, it is recommended to reduce and brake as much as possible.

How to change a lithium battery electric vehicle into a battery electric vehicle?

1. Replace the controller and charger for lead-acid batteries instead of lithium batteries. For example, the undervoltage of the 48v lithium battery controller is 39v, and the undervoltage of the 48v lead-acid battery controller is 42v. If you do not change the controller, the lead-acid battery will discharge to 39v before power off. At this time, the lead-acid battery has been over-discharged and is easily damaged Lead-acid battery, so 48v lead-acid battery controller should be replaced. If you do n’t change the controller, you still have 2 grids to stop driving and charge to avoid over-discharge.

2. The charging current and voltage of lead-acid battery and lithium battery are different, so 48v lead-acid battery charger should be replaced. The 48v lead-acid battery charger is also divided into 20a and 12a, which must correspond to the capacity of the lead-acid battery. If the 20a charger is used to charge the 12a battery, the battery life will be shortened because the charging current is too large.

3. In addition, pay attention to the capacity of the battery. The capacity of the lead-acid battery should not be less than the capacity of the lithium battery, otherwise the distance traveled will be less than the original. For example, if the original 20a lithium battery was replaced with a 12a lead-acid battery, it used to run 60 kilometers, but now it can only run 36 kilometers. The original car beam has a built-in lithium battery. After replacing the lead-acid battery, you can install 4 batteries in the battery box, and then fasten it to the rear frame, and connect the battery power cable to the power socket of the controller.
