Audited Supplier JYT series 3.3KW is a small-sized and high-efficiency charger specially developed by our company for pure electric new energy vehicles such as lithium battery pure electric A0, A00 passenger cars, logistics vehicles, special vehicles, and modified vehicles. Standardized and generalized design ideas for directional research and development. The module is designed with full digital control technology, with flexible and intelligent control, good protection characteristics and strong system adaptability. Using a new generation of phase-shifting and width-adjusting zero-voltage and zero-current soft-switching technology combined with high-performance SiC devices, the whole machine has strong stability and high conversion efficiency, and the peak efficiency can reach more than 94%.
The DC output side of the charger is connected to the positive and negative poles of the power battery, and the AC input is connected to the charging port socket of the vehicle body. The connection between the charger and the battery is shown in the figure below

Protection |
Over voltage protection |
Input overvoltage, it will shut down, it can be self-recovery, output overvoltage, it will shut down, it can be self-recovery. |
|
|
Under voltage protection |
input under voltage, it will be shut down, it can be self-recovery, Output undervoltage, it will be shut down and can be self-recovery |
|
|
Short circuit protection |
output short circuit, it will shut down, it is self-recovery |
|
|
Over temperature protection |
When the temperature of the heat sink is higher than 75 ºC, it reduces the output power. When the temperature is higher than 95 ºC, it disconnects the circuit. When the charging temperature recovers below 85 ºC, the charger recovers the output |
|
|
Reverse connect protection |
The output is inversely connected. When it is powered on and does not start, it will give an alarm. When it is restored, it will work normally |
|
|
Equilibrium potential and ground protection
|
The resistance between the conductive parts that can be directly touched by the human body and the potential equalization point in the vehicle charger shall not be greater than 0.1Ω. The grounding point of the on-board charger should have an obvious grounding mark |
|
|
Power-off protection |
Abnormal state, it will be cut off the power |
