High voltage battery repair kit A cost-effective solution
The high voltage battery - also known as the traction battery - stores the electrical energy needed to power hybrid and electric vehicles: It consists of numerous battery cells that are combined in modules. In hybrid vehicles (HEV), the hybrid battery supports the combustion powertrain in order to reduce fuel consumption. A sustainable and cost-effective solution for selected hybrid vehicles.
Advantages of the high voltage battery repair kit
Safe and long-lasting
The repair kit enables safe repair of the battery. Replacing all modules of the hybrid battery represents a long-lasting repair solution – without further failures.
Saves costs and resources
Compared to a complete battery replacement, only the battery modules and the most necessary attachments are replaced, all other components are reused.
Easy installation
The Bosch high voltage battery repair kit allows the modules to be installed easily by qualified personnel. No vehicle-specific tools or programming of the battery modules are required.
5 year warranty
5 year warranty on the Bosch repair kit confirms its high quality and creates confidence in the functionality and service life of the repair solution*.
Official approval
The repair been approved by the UK Road Vehicles Regulation: no further inspection by the vehicle owner at a test institution is required.
*Five-year warranty starting from the date of purchase for the high voltage battery repair kit delivered by Bosch. The warranty covers defects that occur within the warranty period under normal conditions of use. The warranty does not cover the use of the repair kit in tuned vehicles, driving school vehicles or vehicles used for commercial passenger transportation.

Common signs of complications and FAQ
To ensure a long service life, the hybrid battery must be sufficiently cooled or heated depending on the situation. This is ensured by the thermal management system. If there is a defect in the cooling system, the correct operating temperature can no longer be ensured. This leads to accelerated ageing of the battery cells and the hybrid battery must be maintained. This means that all parts of the air duct must be checked for dirt and blockages.
The cause of higher fuel consumption or a drop in performance in a hybrid vehicle can be the low state of charge (SOC) of the battery and/or the battery capacity, which has decreased due to ageing effects. The battery discharges more quickly or can store less energy. The combustion engine is therefore switched on and consumes more fuel.
Qualified specialists can check the condition of the hybrid battery. If excessive ageing of the battery is diagnosed, replacing the battery modules with the Bosch high voltage battery repair kit is a cost-effective and sustainable solution.
If the hybrid battery warning light comes on, we recommend visiting a workshop to avoid battery failure and thus ensure the vehicle's roadworthiness. A simple and sustainable solution for selected hybrid vehicles is to replace the battery modules with the Bosch high voltage battery repair kit. An expensive complete replacement of the entire battery is not necessary. You can find a qualified workshop near you here.
Error code P0A80 is displayed if the voltage differences between the battery modules within the hybrid battery are too high or too low. In most cases, the code means that the hybrid battery or the control unit must be replaced.
As the battery is an essential component of the drive system, the hybrid vehicle should be checked immediately by qualified specialists. If the battery is defective, we recommend the resource-saving solution from Bosch. This avoids replacing the complete battery.
Within a battery system, all battery modules are connected in series and the weakest module in the chain defines the overall performance. If only the defective modules are replaced, the battery is functional and the vehicle is roadworthy again, but the performance may still be affected by the weaker modules.
As the battery modules are subject to ageing effects, there is also a risk that the high voltage battery will fail again due to the modules not being replaced. Bosch recommends replacing all modules and offers the suitable solution with the repair kit.
Defective high voltage batteries in hybrid vehicles
How do you know that the high voltage battery is defective? Pay attention to the following signs:
- The vehicle issues a warning message
- The fuel consumption is increased
- Electric starting is not possible
- Electric driving is not possible
- Low range when driving electrically
- Little or no recuperation power
- The high-voltage battery is not charged
- The vehicle accelerates poorly
It is easy to check in the workshop whether the traction battery is defective - the diagnostic device then displays an error message. The reason is that every battery is subject to aging processes. If a repair is required, the Bosch high voltage battery repair kit for selected hybrid vehicles is a sustainable and cost-effective solution.
Disadvantages of a complete battery replacement
A complete battery replacement makes neither economic nor ecological sense. Replacing the entire hybrid battery incurs higher costs because it also involves replacing parts of the battery system that are still functional.
With the resource-saving repair solution from Bosch, only the battery modules are replaced, not the entire hybrid battery. If only individual modules are replaced, there is a risk that other modules will reach their lower limit in the foreseeable future and a workshop will have to be visited again. Original, wear-free components of the battery system such as the housing, fan and electronics are reused. Replacing all modules with the Bosch high voltage battery repair kit is a long lasting and cost-effective repair solution for selected hybrid vehicles. Additionally, the modules are easy and safe to install.
With the Bosch high voltage battery repair kit, you expand your service portfolio and strengthen your expertise in the field of e-mobility – for satisfied customers and a future-proof workshop.
