Bosch research: Dr. Thorsten Ochs

In the Bosch center for research and advance engineering in Renningen near Stuttgart, Dr. Thorsten Ochs works on the batteries of the future.

At the inauguration of the Renningen research campus, Bosch announced goals for its battery developments.

50 kWh / 190 kg (419 lbs) → 263 Wh/kg

The 50 kWh pack should weight no more than 190 kg, so if we assume 263 Wh/kg on the pack level (which we are not certain is correct), then the cell level could be much higher.

Bosch expects 15% market share for electric cars around 2025, and invests 400 million euros annually in electromobility to be ready as a leading automotive supplier for the New Energy Vehicles.

The German company also said clearly that by 2020 their batteries should be capable of storing "twice as much energy" while costing significantly less. Twice as much as... (no bottom value included).

Another important goal is charging capability of 15 minutes to 75% state of charge (from an unknown state of charge). For 50 kWh, 0-75% would need at least 150 kW.
