# The product's operating safety is only ensured if the permissible conditions are met.
If a 48 V Energy Storage ES 5-2.4 is stored or not operated it can be stored for 6 months
with start-SOC of ≥30 % for each 48 V Energy Storage ES 5-2.4 without recharging. The
Energy Storages ES 5-2.4 are delivered with an initial SOC ≥25 %. A check of the SOC of
the delivered energy storages is recommended before storage. This applies also for 48 V
Energy Storages 5-2.4 installed in the vehicle.
# The CUSTOMER is responsible for the review and application of all applicable regula-
tions as well as industry standards for lifting deliverables.
# Do not modify or alter any component. In case, it is necessary to modify or alter com-
ponents (e.g. the Energy Storage 5-2.4), contact BOSCH MOTORSPORT in advance.
Energy Storages 5-2.4 have a low internal impedance and may provide damaging currents
if misconnected.
# Reverse polarity and operation with disconnected plug shall be avoided.
# The outer temperature of deliverables increases during operation causing temperature
radiation. If necessary, the CUSTOMER shall install protection for limiting the temperature
radiation. If necessary, the CUSTOMER shall install thermal insulation measures in order to
avoid damage of adjacent components.
The BOSCH MOTORSPORT e-GoKart System is designed for an operation in typical
European climate zones with an ambient temperature of 5 to 35°C. Operation with re-
duced performance is possible for -8 to 40°C ambient temperature. Performance reduc-
tion depends on the application and vehicle design. Charging and recuperation is possible
for >5°C ambient temperature.
Inner temperatures of components might differ from ambient temperature due to installa-
tion position and operation history. The BOSCH MOTORSPORT e-GoKart System measures
the temperature of the 48 V Energy Storage ES 5-2.4 on cell level. If the cell temperature
exceeds defined limits (-8 to 58°C for driving and 5 to 44°C for charging), the BOSCH MO-
TORSPORT e-GoKart System autonomously prevents driving and charging and informs
the driver, see section System Screens [} 14].
Illustration 1: Temperature Range
The BOSCH MOTORSPORT e-GoKart System is designed for an environment with a relat-
ive humidity of 0 to 80 %.
# The CUSTOMER shall ensure that electrical connection and electrical isolation of the
components are reliable over lifetime. It is recommended that during frequent service of
the vehicle the following checks are executed to ensure safe operation:
