Charging Lithium Ion Batteries With Lead Acid Charger

Description

48V lithium battery charger uk Each electric wheelchair must be equipped with a charger. Different brands of electric wheelchairs are often equipped with different chargers, and different chargers have different functional characteristics. The electric wheelchair intelligent charger is not what we call a charger that can store power for mobile use after charging. The electric wheelchair intelligent charger refers to a charger device that can automatically power off after the device is fully charged. Now most chargers will continue to provide power after our equipment is fully charged, which will lead to over charging, explosion and damage of electrical equipment.

1、 Working principle

Intelligent electric wheelchair charger is generally used with pressure measuring device. What is pressure measuring device? This is a device that can stop charging the current at its own middle end. We usually use chargers without such devices, so our chargers will be more hot, serious when serious electrical equipment explosion and damage. The price of intelligent electric wheelchair charger will be more expensive, because the equipment and control system used are relatively advanced, and it is a safe and reliable high cost-effective charger.

The principle of intelligent electric wheelchair 25.2 v lithium ion battery charger is also very simple, because it is equipped with pressure measuring device and metal diaphragm. When we charge, the pressure measuring device will automatically conduct pressure measurement. When our device is charged, the charger will automatically convert the current inside, and the current will be converted into trickle.

Trickle charging is very slow, almost as a state of stopping charging. The control equipment used in intelligent electric wheelchair charger is different, but it mainly uses some devices to change current to control the current circulation, so as to achieve the effect that full power will automatically cut off. The security performance of intelligent charger is relatively high, it can solve the problem of overcharge perfectly, make the equipment more safe when charging, and will not waste electricity, it is a safe and environmental protection device.

How to using the lithium ion battery full charge voltage?

1. For the new wheelchair purchased, the battery may be low due to long-distance transportation, so please charge it first and then use it.

2. Check whether the rated input voltage of charging is consistent with the power supply voltage.

3. The battery can be charged directly on the vehicle, but the power switch must be turned off, or it can be removed and taken to a suitable place such as indoor for charging.

4. Please connect the output port plug of the charging appliance with the charging jack of the battery, and then connect the plug of the charger to 220V AC power supply. Be careful not to mistake the positive and negative sockets.

5. At this time, the power supply and charging indicator red light on the charger is on, indicating that the power supply has been connected.

6. One time charging takes about 5-10 hours. When the charging indicator turns from red to green, it indicates that the battery is fully charged. At this time, if time permits, it is best to continue charging for about 1-1.5 hours to make the battery obtain more energy. However, do not charge continuously for more than 12 hours, otherwise it is easy to cause deformation and damage to the battery.

7. After charging, unplug the AC power supply first, and then unplug the plug connected with the battery.

8. It is forbidden to connect the charger to AC power supply for a long time without charging.

9. Maintain the battery every one to two weeks, that is, after the green light of the charger is on, continue charging for 1-1.5 hours to prolong the service life of the battery.

10. Please use the special charger provided with the vehicle, and do not use other chargers to charge the electric wheelchair.

11. When charging, it shall be carried out in a ventilated and dry place. The charger and battery shall not be covered with anything.
