Greg Ceisel is the Chevy Volt Program manager and has integral knowledge about the car’s engineering.
He recently shed some light on how the battery pack detects and reacts if there are any problems.
“The reliability of the Chevy Volt and its battery are essential to the success of this technology,” he said. “Our battery design includes multiple computers that run hundreds of tests to monitor the cells and the overall battery to confirm everything is working correctly.”
He explains that all of this testing is continuous and automatic and that the system is designed to respond in case of trouble.
“If any of these tests identify an issue a diagnostic trouble code (DTC) is set to identify the specific issue and an indicator light on the instrument panel will light informing the driver that service is needed,” said Ceisel.
Ceisel also notes GM’s satellite system OnStar can help out both the driver and the mechanic in this situation.
“If the driver wants immediate feedback, OnStar can access these codes to provide more information,” he said. “These codes will also provide the dealer technician with specific information on the repair required.”
He explains how the battery cells are configured both in parallel and series and how the failure of some cells wont take down the car. If need be, the generator can also be used to help out.
“If a diagnostic issue is detected the control system will adapt to use available battery power and, if needed, the gas engine/generator to maintain propulsion until the vehicle can be serviced,” he said.
