Type and specifications of electric vehicle charger

There are many types of chargers, generally smart two-stage, intelligent three-stage and full smart charger.

1. Intelligent two-stage charger

The charger's charging mode can be divided into constant current charging and floating charging. In the first stage of the two-stage charging, the current is negatively inverted and the feeding is dominant, that is, the constant current phase; the second phase is floating charging, that is, trickle charging of the battery.

2. Intelligent three-stage charger

In the first stage of intelligent three-stage charging, the current negative feedback plays a leading role, that is, the constant current stage; the second stage is dominated by the current negative feedback and gradually shifts to the voltage negative feedback to play a leading role, that is, the constant current stage. The transition to the constant voltage phase; the third phase is the negative voltage feedback, which is the constant pressure phase. It has the advantage of effectively extending the life of the battery.

3. Full smart charger

When the battery is charged in a de-energized state, the voltage and current required to supply the battery to the all-intelligent charger is an automatic conversion process, rather than an artificially programmed procedure. The all-intelligent charger provides a suitable charging voltage and current to the battery based on the battery's loss of power.

Hint:Smart charger

The smart charger is a charger that can be used for fault detection and unmanned management using a single-chip microcomputer or an ASIC. It has the following characteristics.

1 can output a variety of charging modes according to the battery's power loss, to ensure that the battery pack is not undercharged, but not charged.

2 The charger has a multi-stage charging mode, which can automatically adjust the voltage or current value of its charging and discharging.

3 If the battery plate is vulcanized, the negative pulse desulfurization process can be automatically adjusted to extend the service life of the battery.

4 Automatically equalize the charge to ensure that each single battery in the battery pack is well charged.

5 can automatically detect the type and temperature of the battery. During the charging process, if the temperature of the battery exceeds the specified value, the charger can automatically stop charging.

4. Electric tricycle commonly used in electric tricycles

The electronic chargers commonly used in electric tricycles are mainly 36V/20A, 48V/20A, 48V/40A, 48V/60A, 48V/80A, etc. These are mostly used in elderly electric tricycles and passenger electric tricycles.

5. The model of the electric bicycle commonly used charger

The models of electric bicycles commonly used are as follows.

1. 64V/20A (square port charger), suitable for 64V/20A battery electric vehicles.

2. 60V/20A (square port charger), suitable for 60V/20A battery electric vehicles.

3. 60V/12A (square port charger), suitable for 60V/12A battery electric vehicles.

4.48V/20A (square port charger), suitable for 48V/20A battery electric vehicles.

5.48V/12A (round port charger), suitable for 48V/12A battery electric vehicles.

6.48V/12A (square port charger), suitable for 48V/12A battery electric vehicles.

7.36V/12A (square port charger), suitable for 36V/12A battery electric vehicles.

8. 36V/12A (round port charger), suitable for 36V/12A battery electric vehicles.
