In essence, if the original vehicle is safe, then MTG’s vehicle battery replacement is also safe. Over the years, the lithium battery industry has undergone rapid development, with significant advancements in battery performance and safety.

1. Rapid Advances in EV Manufacturing: Over the past decade, the EV manufacturing industry has experienced rapid growth, with assembly technology evolving significantly. MTG benefits from using state-of-the-art manufacturing processes that have improved to match or even exceed the original vehicle’s specifications, ensuring that the replacement battery meets high standards of safety and performance.

2. Improved Energy Density: The energy density (Wh/kg) of lithium batteries has greatly improved in the past decade. The same volume or weight of battery cells can now store 2-3 times more energy. The new battery modules used for replacements increase energy capacity without significantly changing their volume or weight, ensuring that vehicle balance and heat dissipation are not negatively affected.

3. Retaining the Original Vehicle’s Design Integrity: MTG’s battery replacement process preserves the original vehicle’s structure, battery management system (BMS), and production processes. The design of the vehicle’s power systems already ensures high security and redundancy, so no changes are required to the vehicle’s original design during the battery replacement. This provides peace of mind regarding safety and vehicle performance.

MTG의 배터리 모듈 제품은 중국 본토 시장에서 BYD, GAC, BAIC 모델의 절반 이상을 커버합니다.

For global models, battery modules for BMW i3 and NISSAN Leaf have been successfully launched, with several hundred units already sold. The VW e-golf is currently undergoing road testing. Our R&D plans also include battery upgrades for the following models in the future:

• RENAULT Zoe
• Hyundai Kona EV
• Audi E-tron series
• VW ID3, ID4, ID6 series
• MG series
• PEUGEOT 208EV, etc.

If you are a bus company or have a transportation fleet that needs battery upgrades or R&D support, please contact us. Additionally, if you have electric vehicles experiencing battery degradation, we offer battery replacement services, as we are highly experienced in this field.

The cost of BMW i3, VW E-golf, and Leaf battery replacement and upgrade largely depends on the specific model and the scope of the battery upgrade. We do not sell modules directly to individual car owners. Instead, please contact a local EV repair shop to work with us on this matter.

Once the repair shop is involved, the battery modules will be installed by certified professionals, and the specific details (such as vehicle handover, installation, test driving, and payment) will be coordinated with them. For most models, the complete vehicle battery replacement can be done within 3 working days.

In terms of pricing:

• The warranty policy will follow the terms of the local distributor’s warranty policy.
• After the warranty period, repairs will be charged at labor costs and material prices lower than the market rate.
• The battery modules feature a detachable assembly structure, which supports the replacement of individual cells, providing a more affordable solution for repair shops and significantly lowering maintenance costs for vehicle owners.

국가마다 세금, 인건비 및 유통 경로의 차이로 인해 동일한 MTG 배터리 모듈에 대해 다른 차량 소유자가 다른 가격을 지불합니다. 우리의 글로벌 가격 책정은 두 가지 원칙을 따릅니다:

1. 동일 용량의 모듈을 교체하는 가격은 원래 배터리 모듈 견적의 45%~65%에 해당합니다.
2. 중고차 거래 가격에 MTG 차량 교체 비용을 더한 금액은 현지에서 동일 수준의 새로운 전기차를 구매하는 가격의 50%에 불과합니다. MTG는 전 세계 전기차 소유자들이 합리적인 가격으로 더 긴 주행 거리를 얻을 수 있도록 최선을 다하고 있습니다.

The MTG battery replacement modules generally outperform the original vehicle battery in terms of both charging and discharging capabilities, thanks to continuous technological advancements. In other words, the MTG modules can charge as quickly as the original factory battery, fully supporting the original factory’s fast charging system.

However, when it comes to third-party fast chargers, while the MTG battery modules are theoretically capable of working with them, MTG exercises caution regarding their installation and use. This is due to the difficulty in controlling the current size with third-party charging systems, which could potentially harm the battery if the charging current exceeds a certain limit.
