press release

Since 2007, automotive manufacturers have been using start/stop systems developed by Bosch in series production. From that time onwards, the proportion of passenger cars fitted with the fuel-saving system has been continuously on the up. The systems reduce fuel consumption and CO2 emissions in the “New European Driving Cycle” by up to five percent, and by up to eight percent for city driving. By as early as 2013, every second new passenger car – from small vehicles to luxury saloons right through to high-performance sports cars – is likely to be fitted with a start/stop system.

As a consequence, more vehicles with start/stop technology will be coming into vehicle repair shops for service and repair work in the future. Bosch therefore offers an extensive range of spare parts, diagnostic devices, and services for the repair and service of fuel-saving start/stop vehicles.

Comprehensive Testing Technology and Service Equipment Range for Start/Stop Components
Many vehicles featuring start/stop systems require repair shop expertise when it comes to changing the battery. This is because the new battery needs to be registered with the battery management system, normally with the aid of a diagnostic tester such as a device from the Bosch KTS range. The corresponding Bosch Esitronic diagnostics software covers all relevant start/stop vehicles and also provides technical information such as service and repair instructions, system information and spare parts catalogs. The BAT 131 battery tester is suitable for checking the status of start/stop batteries with AGM technology. Bosch offers the BAT 415, 430 and 490 battery chargers for charging the start/stop batteries. The functionality of the relevant sensors of the start/stop system is tested using the Bosch FSA vehicle system analysis. In addition, the FSA 500 or FSA 740 modules can be used to check the vehicle battery charger, for example.

Special High-Performance Batteries, Starters, and Alternators
The Bosch spare parts range for start/stop systems in original equipment quality covers all important components of the system. Start/stop systems apply high standards, particularly with regard to starters, alternators and batteries. The battery must provide strong performance, be deep-cycle resistant and be capable of charging quickly. It must provide the energy required for the frequent engine starts and supply the ongoing electrical consumers during the stop phase. The Bosch S5 batteries with EFB (enhanced flooded battery) and the S6 batteries with AGM (absorbent glass mat) technology fulfill these requirements. When changing batteries, it is essential that an EFB battery is replaced with another EFB or an AGM battery; this ensures the start/stop function will continue to operate. If an AGM battery was installed as original equipment, another AGM battery must be used as its replacement. The correct battery is defined in the Bosch Esitronic Software equipment list; the list also provides instructions on how to replace the battery.

The starters specially developed by Bosch for start/stop systems have also been designed for a considerably higher number of start operations and therefore include features such as reinforced bearings, improved planetary gears and an optimized commutator. Bosch efficiency line alternators for start/stop systems have a particularly high degree of efficiency. Even in low speed ranges and immediately after a vehicle start, they generate more electrical energy to supply the electrical system, thereby ensuring rapid recharging of the battery and increasing the availability of the start/stop function.

In addition, the spare parts range for start/stop systems also includes Bosch control units with start/stop function, sensors (such as battery or wheel speed sensors) and DC/DC converters. The converters stabilize the vehicle electrical system voltage when the vehicle is started and ensure that the radio, navigation system and hands-free devices can be operated without interruption.

Training and Technical Hotline
Bosch offers specialist training to ensure safe handling of start/stop technology in the 43 Bosch Service Training Centers worldwide. The specialists on the Bosch technical hotline also support the repair shop associates in all questions and problems related to start/stop technology.

The Automotive Aftermarket division (AA) provides the aftermarket and repair shops worldwide with a complete range of diagnostic and repair shop equipment and a wide range of spare parts – from new and exchange parts to repair solutions – for passenger cars and commercial vehicles. Its product portfolio includes products made as Bosch original equipment, as well as aftermarket products and services developed and manufactured in-house. More than 18,000 associates in 150 countries, as well as a global logistics network, ensure that some 650,000 different spare parts reach customers quickly and on time. In its “Automotive Service Solutions” operations, AA supplies testing and repair-shop technology, diagnostic software, service training, and information services. In addition, the division is responsible for the “Bosch Service” repair-shop franchise, one of the world’s largest independent chains of repair-shops, with some 17,000 workshops. In addition, AA is responsible for more than 1,000 “AutoCrew” partners.
