Vehicle diagnostics and EV battery service in one system.
CE39 links a diagnostic tablet with a battery-module service unit. Supported vehicle diagnostics can continue while cell equalization, charging or discharging is monitored. Technicians get battery data, controlled module service and a clear view of the work in one system.
Four functions. One workflow.
Four functions
Diagnostics, equalization, charging and discharging in a connected workflow.
24 cells
Two banks of 12 channels equalize up to 24 cells in a compatible module.
Parallel operation
Supported diagnostics and module service monitoring can run at the same time.
CE39 in the workshop
Vehicle diagnostics
On supported systems: read and clear fault codes, view live data, perform actuator tests and service functions. Network topology helps locate communication faults.
Battery pack inspection
Read available SOC/SOH, individual cell and module voltage, temperature and faults. Review pack voltage and cell-voltage differences.
Offline component tests
With the required connections and supported application: batteries, traction motors and electronic controls, including DC/DC converters, onboard chargers (OBC) and electric compressors.
Cell equalization
Configure and monitor up to 24 module cells. Common lithium chemistries are supported with settings matched to the battery.
Module charging and discharging
Charging current up to 40 A and discharge current up to 20 A, within the applicable power and voltage limits. Follow voltage, current and progress on the display.
Remote monitoring and updates
Supported remote device-status monitoring and software updates according to the supplied configuration.
System protection
Monitoring for overvoltage, undervoltage, overcurrent and overheating, as well as short circuit and reverse polarity.
Tablet and service unit
The diagnostic tablet presents the measurements and workflow; the service unit controls module charging, discharging and equalization.
