When the detection tool indicates an issue with the internal cells of the battery pack, technicians typically replace the entire module (as repairing individual cells is challenging and time-consuming, hereby ref. to EVB624/ELB300 for cells balancing). After replacing the module, the EVP711 can be used for balancing. Once the voltage of the module is consistent, it can be installed into the vehicle.
During the balancing process with the balancer, it may take a considerable amount of time to complete. In such cases, you can use the EVP711 to charge the battery module first. When the voltage levels are approximately equal, use an equalizer(such as EVB624/ELB300) to balance the cell voltage consistency. Combining the use of the equalizer and the charge&discharge tool improves repair efficiency.

4. Security features
The EVP711 is equipped with a range of safety functions, including reverse polarity protection, overtemperature protection, overcurrent protection, fan failure detection, overvoltage warning and overcurrent warning. All of these functions contribute significantly to the safety of the operator.

The new EVP711 is designed to support the charging and discharging of lithium and nickel-metal hydride batteries.
The new EVP711 is capable of recording and displaying real-time data on the terminal voltage of the battery pack and the voltage of the individual cells.

Technical Profile:

After the repair of the battery or modules inside the battery pack is completed, it is necessary to conduct a sealing test before installation. Without this test, if the sealing is inadequate and the vehicle drives on wet roads, it can easily lead to water ingress into the battery pack, causing internal circuit short circuits and ultimately accidents. Therefore, testing the sealing of the battery pack is a mandatory requirement.

Features:
Ø Preset battery pack parameters such as: volume, pressure, stage testing time, leakage limit, etc.
Ø High-sensitivity pressure sensing, high testing accuracy and stability.
Ø Equipped with a pressure gauge to display a real-time pressure curve during the process, making the testing process clear at a glance.
Ø Supports multiple languages, including: Traditional Chinese, English, German, French,Japanese, Spanish, Portuguese, Italian, etc.

Functions:

1. Highly sensitive sensor
The accuracy and stability of the test is improved by the revised pressure sensor technology.

2. Visualisation of the process

4. Parameter monitoring
The time required for each phase of the examination procedure can be displayed.

5. Personalised settings
Parameters such as volume, pressure, duration of each phase and leakage limit value can be defined in advance.

6. Intelligent warning
The device emits an audible and visual alarm if the values are abnormal or if the test is not passed.
