Case Study

Overseas battery-line engineering support

Challenge

The construction of overseas production lines and the upgrade of testing platforms need to be coordinated and meet the requirements of local equipment interfaces, electrical conditions, and English delivery documents.

What we did

The work recorded in the original materials includes testing system adaptation, upgrading existing platforms, creating new testing sections, and providing on-site installation, debugging, and acceptance document support.

Result

Can form a unified testing caliber and deployment baseline. The original manuscript records the status of delivered and in progress for different production lines; This time, it was not merged and recognized as fully completed.

Multi-site line retrofit and overseas deployment

Challenge

There are differences in battery models and production line conditions among different bases, and it is necessary to complete compatibility modification of existing testing equipment within the shutdown window and support overseas re debugging.

What we did

Using the existing hardware platform, carry out engineering transformation around tooling, software configuration, testing item addition and removal, and compatibility after transfer.

Result

The original material explains the path of hardware reuse and cross base adaptation; The acceptance, settlement, and ongoing procurement of each base must be reconfirmed according to project records.

Integrated battery-line test systems

Challenge

The construction of multiple bases requires simultaneous consideration of testing processes, energy management, and consistency of testing data, and enables the reuse of system design for new production lines.

What we did

The scope of the original manuscript includes the design and integration of battery cell testing systems, common DC bus energy scheduling, and production line systems.

Result

The original manuscript provides a plan for cross base unified testing caliber and data model. The energy saving range, quality assurance conditions, and completion status of each base have not obtained the original proof in this case, and the candidate text does not include numerical values.

Core-component testing for a vehicle production line

Challenge

The incoming materials and process testing before loading need to cover electrical performance, leakage, signal simulation, and communication testing, and be coordinated with the production line rhythm.

What we did

Modular testing functions are combined by workstation, including multi-channel resistance simulation, leakage measurement, AC internal resistance and communication testing, etc.

Result

The original manuscript describes the method of configuring test items and uploading data by workstation on the same platform; Actual pace, detection coverage, and acceptance results still require project evidence.

AI battery models for BMS HIL validation

Challenge

Fixed parameter battery models are difficult to cover actual aging and temperature differences, and BMS validation requires models and test cases that are closer to actual operating conditions.

What we did

The original manuscript describes the solution of combining AI battery model with BMS HIL platform, and proposes to update the model and use cases using production line and in use data.

Result

Improved efficiency in qualitative description verification of old drafts; No quantitative comparison or operational records have been obtained this time, and no improvement percentage is given, nor is it verified that continuous data return has been put into operation.

Aftermarket work-order data feedback

Challenge

R&D and mass production use cases need to be combined with fault information from real use, and detection, maintenance, and re inspection records are often scattered across different terminals.

What we did

The original manuscript proposes to return the work order records of networked detection and maintenance equipment according to the agreement, and to precipitate fault, threshold, and operating condition information through a unified data model.

Result

Can be used to illustrate the business path of post market data return; The number of terminals, activity rate, work order volume, and statistical cycle are still lacking in the bottom table, and these numbers will not be cited in the candidate copy.

Battery motor and vehicle-control validation

Challenge

Multiple types of electrical signals and complex working condition combinations need to be verified in a unified environment, and manual execution of each item is difficult to maintain consistency in working conditions and records.

What we did

The scope of the original manuscript includes typical and custom operating conditions, automation scripts, signal sampling, fault injection, real-time simulation, and report generation.

Result

The original manuscript describes the combination of working conditions, which is executed in batches according to the script and automatically generates reports; The current delivery status and actual efficiency benefits need to be supplemented with acceptance or operation records.

Integrated vehicle-cloud OTA testing

Challenge

OTA verification involves the vehicle side, cloud side, communication link, and application side, and requires verification of the update process under various network and power supply conditions.

What we did

The scope of the original manuscript includes power supply, bus, network, cloud and node simulation, LIN, CAN, CAN FD and vehicle Ethernet, as well as custom detection methods.

Result

The original manuscript describes a unified automated process that covers multiple stages of verification; It is not based on this to determine that the concurrency scale, data compliance, or any admission requirements have been fully validated.

BMS validation and aftermarket diagnostics

Challenge

The validation and in use diagnosis of battery management algorithms involve data from different stages, requiring a correlation between the validation environment and the diagnostic process.

What we did

The original materials include BMS HIL platform, aftermarket diagnostic framework, and remote diagnostic direction; Different cooperation scopes should be confirmed and divided according to corresponding projects.

Result

The existing data can support the historical draft of cooperation direction and system functions; The original statistical basis for the decrease in defect rate and the extension of lifespan is still lacking, and relevant quantitative propaganda has been removed from this article.

Vehicle-controller validation system

Challenge

The validation of the vehicle controller requires simultaneous simulation of temperature, switch values, sensor protocols, wheel speeds, and multiple bus signals.

What we did

The original manuscript describes configuring temperature sensors and switch quantities on the same rack SENT/PSI5、 Wheel speed and simulation of CAN, LIN, and onboard Ethernet signals.

Result

The original manuscript describes the generation of multiple types of signals on the same platform, batch execution of scripts, and retention of test records; No quantified results have been provided, and no revenue figures will be added to this manuscript.

Shared DC bus and co-located storage dispatch

Challenge

The fluctuation of battery cell capacity load and discharge feedback energy need to be considered in conjunction with the distribution capacity, energy storage charging and discharging, and electricity price window of the factory area.

What we did

The original manuscript includes the design of the common DC bus system, testing and integration of energy storage units, debugging, and data tracking after commissioning.

Result

The original manuscript includes operational data for specific months and climbing conditions, but no minute data or issued reports were obtained this time; This manuscript retains the technical path and will fill in the performance results once the evidence is complete.

Test equipment for storage-battery production

Challenge

The manufacturing process of energy storage batteries requires offline configuration, electrical performance and airtightness testing according to product voltage and process requirements, and retention of factory inspection records.

What we did

The original manuscript involves PACK-EOL, PACK line testing, and mass flow type airtightness tester; Project records should be established separately for customers and equipment.

Result

This article summarizes multiple customer projects and cannot be considered as a unified completed project. Their respective delivery or execution status, equipment configuration, and acceptance results still need to be separated.
