What is a GB/T Charger?
1. Charging standards for mainstream electric vehicles
Thanks to the boom in the new energy industry, the electric vehicle charger industry also develops rapidly. Many countries engage in fierce competition specific to the electric vehicle charger market, among which the main one is the electric vehicle charging standard. At present, there are three main groups of charging standards for new energy vehicles: Type1 (American standard); Type2 (European standard), utilizing the SAE J1772 standard led by the international society of automotive engineers (SAE); and GB/T, Chinese standard as well as CHAdeMO (Japanese standard), first introduced in 2010 by the Japan Electric Vehicle Association and the Japan Electric Vehicle Charging Association.
As the name implies, the GBT Charger of AG ELECTRICAL is based on the Chinese standard.
2. GB/T standard
On December 28, 2015, five newly revised national standards for charging interfaces and communication protocols for electric vehicles were issued in Beijing by the Standardization Administration of the Chinese General Administration of Quality Supervision, Inspection and Quarantine together with the National Energy Administration, the Ministry of Industry and Information Technology and the Ministry of Science and Technology. The new standards took effect on January 1, 2016. The GB/T standard is divided into three parts: the general requirements, AC and DC and the communication between the charger and BMS, specifically listed as follows:
(1) GB/T 18487.1-2015 Conducting Charging Systems for Electric Vehicles – Part 1: General Requirements
(2) GB/T 20234.1-2015 Connectors for Conducting Charging for Electric Vehicles – Part 1: General Requirements
(3) GB/T 20234.2-2015 Connectors for Conducting Charging for Electric Vehicles – Part 2: Alternating Current Charging Interfaces
(4) GB/T 20234.3-2015 Connectors for Conducting Charging for Electric Vehicles – Part 3: Direct Current Charging Interfaces
(5) GB/T 27930-2015 Communication Protocol between Off-board Conductive Charger and Battery Management System of Electric Vehicle
The introduction of GB/T standard improves the safety and compatibility of charging.
(1) Security
GB/T standards increase the functions like charging interface temperature monitoring, electronic lock, insulation monitoring, discharge circuit, etc., elaborate the vehicle interface of DC charging security protection measures and explicitly prohibit unsafe charging mode application. Thanks to the efforts, personnel electric shock, equipment combustion and other accidents are effectively avoided, and the safety of electric vehicles and users during charging are guaranteed.
(2) Compatibility
The type and structure of AC-DC charging interface are compatible with the original standard. The GB/T standard modifies the size of some contacts and mechanical locks, but the new and old plugs and sockets can cooperate with each other, and the electronic locking device added to the DC charging interface does not affect the electrical connection between the new and old products. Users only need to update the communication protocol version to realize the basic charging function of new power supply equipment and electric vehicles.
The GB T charging cable manufactured by AG ELECTRICAL complies with the regulations and requirements of GB/T20234.2-2015 and GB/T18487.1-2015, which, with higher compatibility, can charge all electric vehicles made in China and correctly and effectively convert them to applicable point current.

How Do We Know if an EV Charger is Broken?
1. External causes of damage to electric vehicle chargers
Electric car chargers have a normal life of 5-8 years. In fact, electric car chargers are mature products, difficult to damage, most of the damage is caused by external causes. The peak time of charger damage is during the hot, rainy and humid summer.
The external cause is: the charging environment is not well ventilated and high temperature, it’s easy to burn the charger for a long time. The electric vehicle charger fan is damaged and cannot dissipate heat, causing high temperature damage to the charger. Get caught in the rain or brush the electric car charger into water, resulting in a short circuit inside the charger burned out. Power plug long-term bad contact, voltage instability resulting in damage to the charger. There are also cases where the 220 volt electric car charger is connected to 380V by mistake, it resulting in high-voltage breakdown of the charger components.
2. Common sense of fault detection (low voltage below 96V)
The current electric car chargers are mostly intelligent chargers. During the test, the output terminal must be connected to the battery, and the charger will normally output current only when it recognizes the voltage, if not connected, the output is 0. For 48V charger, the terminal voltage of the battery is lower than 42V, the charger does not work. For a 60V charger, the terminal voltage of the battery is lower than 52.5V, the charger does not work. For 72V charger, the battery terminal voltage is lower than 63V, the charger does not work. The old chargers will burn if they are connected in the opposite direction. The new charge has reverse connection protection, if the positive and negative chargers are connected in reverse, they will just not run, will not damage the electric car charger.
3. Can electric car chargers be repaired?
The answer is yes, it can be repaired. As long as the electric car charger is not
filled with potting inside, it can be repaired. And it is recommended that the ordinary charger of a low speed car should not be repaired. Now a new charger is very cheap, high efficiency, good quality, and energy saving. It is also more intelligent and does not save money on repair.

GB/T EV Charging-FAQs
What does the EV Charging Standard Mean?
At present, the EV charging interface standards are not untied throughout the world, and they are roughly divided into three categories: one is the American standard, one is the European standard, and the other is the China standard. According to the latest mainstream GBT EV charging technology, DC charging (DC) standard and AC charging (AC) standard are popular ones all over the world.
What are the Function of Solenoid Locks?
The solenoid lock is used to fix the socket and anti-theft.
What's the Difference between AC and DC?
Ac and DC EV charging interface is different. Dc power supply is larger, and has faster charging speed. It can save time, and is suitable for short stay destination users. However, the power of ac charging is smaller, which is suitable for occasions where the charging time is not sensitive such as home EV charging or Hotel EV charging.
Do the GB/T EV Charging Products Meet the Standards?
The products of the national standard are in line with the provisions and requirements of GB/T 20234.2-2015 connection device for conductive charging of electric vehicles. Besides GB/T, AG ELECTRICAL also has a variety range of charging interfaces and charging methods that conform to IEC and SAE standards. They are applicable for different brands of electric vehicles and charging stations.
What are the Advantages in Materials?
AG ELECTRICAL use reliable materials with test of flame retardant, pressure resistance, abrasion resistance, impact resistance, high oil resistance. Safety insulation design is adopted to prevent accidental contact with human hands. The cable insulation adopts XLPO to prolong the aging life, and the sheath adopts TPU to improve the bending life of the cable.
