High-voltage battery with cooling
CAUTION!
Damage to the high-voltage battery from stepping on or placing objects on
it!
This can result in malfunctioning or material damage.
■
Never step on the high-voltage battery.
■
Never use the high-voltage battery as a support surface or lean on it.
■
Do not place any objects on the high-voltage battery.

High-voltage battery
The DEEP BLUE system is supplied with energy via a BMW i3 30.5 kWh high-voltage
battery.
When installed in motorboats, ocean-going yachts, and boats which are transported
on trailers, special damping elements are used.
For safety reasons, a ventilation system must be installed in enclosed boats.
ADVICE
Ensure sufficient ventilation of the high-voltage battery.
■
Heat build-up can occur if the environment is not sufficiently ventilated.
■
In the event of damage, hot or poisonous gases may escape from the bat-
tery.

The high-voltage battery’s cooling system has its own cooling water pump for sea
water and a cooling compressor. It works using a special coolant and a heat ex-
changer which transfers heat energy to sea water.
Under heavy loads, the active cooling module ensures a constantly low operating
temperature. This increases the availability and extends the high-voltage battery’s
service life.
