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.

MTG的電池模組產品覆蓋了中國大陸市場超過一半的比亞迪、廣汽和北汽車型。

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.

由於不同國家的關稅、人工成本和分銷環節的差異，不同車主購買相同的MTG電池模組時價格不同。我們的全球定價遵循兩個原則：

1. 更換同等容量的電池模組價格相當於原電池模組報價的45%-65%。
2. 二手車交易價格加上MTG車輛更換費用僅相當於當地購買同級別新電動汽車價格的50%。MTG致力於讓全球電動汽車車主以可承擔的價格獲得更長的續航里程。

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.
