Energy Recovery; Braking Assistance; Range - Bosch Drive Unit Speed Manual Original

6.2.1 Energy recovery

In technology, "recovery" relates to the feeding of elec-
tricity back into the battery during downhill riding. This
means that, if you have set the energy recovery or brak-
ing assistance, you can charge the battery whilst riding
(➠ Chapter 6.2.2 "Braking assistance").
The energy recovery can be set using the arrow buttons.
The higher the energy recovery setting, the stronger the
deceleration. This works in the speed range between 10
and 28 km/h and only while the battery has enough
capacity to store the electricity. This means that, when the
battery is fully charged, energy recovery does not work.
Energy recovery can only be activated when the battery
charge state falls below 90%.
If electricity is being fed back into the battery, you will
see this symbol on the display:
Energy recovery

6.2.2 Braking assistance

If braking assistance is activated, you will see the follow-
ing symbol on the display:
Braking assistance
The braking assistance should make riding downhill more
comfortable and safer for you.
You can set a "limit speed" of up to 25 km/h. The drive
system will then hold you at this speed when riding down-
hill. The output limit of the braking assistance is deter-
mined by the gradient of the route, the total weight of the
vehicle and the battery charge state. The battery charge
state must be no higher than 90%. The temperature range
of the battery must be between 0°C and 45°C.
If the hill is too steep or the gross weight of the bike is
too high, the braking assistance will switch itself off. If
you want to maintain this speed, you must brake using the
brakes on your bike.
As soon as you begin to pedal, the braking assistance
deactivates automatically. It activates once more as soon
as you stop pedalling and are riding at a speed below the
limit speed set.
Always be ready to brake, as the braking assistance
can switch off.
You can, of course, always use the brakes on the bike to
bring the speed of the vehicle below the limit speed once
more.

Range

The distance you can travel using the power assist with
the battery fully charged depends on several factors:
• Selected assist level
If you want to cover a long distance with power as-
sist, select the smaller gears, i.e. the ones that are
easier to pedal. Also select a low assist level.
• Handling
If you are riding in gears that are harder to pedal
and select a high assist level, the motor will pro-
duce plenty of power to help you along. However,
just as with driving a car at high speed, this leads
to higher consumption. You will therefore have
to recharge the battery sooner. You can conserve
energy by keeping the load on the pedals even
throughout the entire crank revolution.
• Ambient temperature
If it is colder, you will travel a shorter distance
with the same battery charge.
To maximise the distance you can travel, keep the
battery in a heated room so that it is at room tem-
perature when you fit it on your Pedelec.
As the battery discharges when the motor is in use,
it generates enough heat to not lose too much of
its power at low ambient temperatures. The bat-
tery cells can discharge at temperatures of -15 to
+60°C.
This is also the temperature range within which
you can use your battery.
