High-voltage battery
In particular, the function of the radar sensors can be impaired in the case of:
- there is dirt on the sensors or anything else covering the sensors
- there is snow or heavy rain
- there is interference by other radar sources
- there are strong radar reflections, for example in parking garages
- a narrow vehicle traveling in front, e.g. a motorbike
- a vehicle traveling in front on a different line relative to the center of your vehicle
Following damage to the front end of the vehi-cle, have the configuration and operation of the radar sensors checked at a qualified spe-cialist workshop. This also applies to colli-sions at slow speeds where there is no visible damage to the front of the vehicle.
If the radar sensors are not available, the sys-tem switches automatically to level D with moderate recuperation. Have the radar sensors checked at a qualified specialist workshop.
Automatic adjustment of recuperation on downhill gradients
The vehicle can detect steep downhill gradients. To reduce acceleration downhill and to charge the high-voltage battery, recuperation is increased steplessly. This is comparable to the engine brake in a combustion engine when you downshift a gear on a downhill gradient.
Automatic adjustment of recuperation on downhill gradients is available in level DAUTO or on vehicles without steering wheel paddle shifters in level D.
Intelligent recuperation
The vehicle uses the map and camera data of Traffic Sign Assist in addition to the sensors of COLLISION PREVENTION ASSIST PLUS during radar-based recuperation (DAUTO). The rate of recuperation is then automatically adjusted to the current traffic situation, taking the current and future maximum speed into account.
Important safety notes
DANGER The vehicle’s high voltage electrical system is under high voltage. If you modify components in the vehicle’s high-voltage electrical system or touch damaged components, you may be electrocuted. The components in the vehi-cle’s high-voltage electrical system may be damaged in an accident, although the damage is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-voltage components and never modify the vehicle’s high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle’s high-voltage electrical system checked by a qualified specialist workshop.
In the event of a vehicle fire, the internal pressure of the high-voltage battery can exceed a critical value. In this case flammable gas escapes through a ventilation valve on the underbody. The gas can ignite. There is a risk of injury.
Leave the danger zone immediately. Secure the danger area at a suitable distance, whilst observing legal requirements
If you use incorrectly installed mains sockets or adapters, extension cables or similar to connect the charging cable to a mains socket, this could lead to fires or an electric shock. There is a risk of fatal injury.
To avoid hazardous situations, observe the following:
- Only connect the charging cable to mains sockets that:
- are installed correctly and
- have been approved by an electrical specialist.
- For safety reasons, only use the charging cables supplied with the vehicle, or charging cables that have been approved for use with this vehicle.
- Never use a damaged charging cable.
- Do not use:
- Extension cables
- Cable drums
- Multiple sockets
- Do not use a socket adapter to connect the charging cable to the mains socket. The only exception is if the adapter has been tested and approved by the manufacturer for charging the high-voltage battery in an electric vehicle.
- Always observe the safety notes in the socket adapter’s operating instructions.
The vehicle’s high voltage electrical system is under high voltage.
- Do not handle high-voltage components or the orange cables of the vehicle’s high-voltage electrical system.
- Do not touch high-voltage components or the orange cables of the high-voltage elec-trical system when a vehicle has been involved in a crash.
- Do not touch any damaged components or damaged orange cables of the vehicle’s high-voltage electrical system.
- Do not remove the covers of the high-voltage electrical system components that are marked with a warning sticker.
General notes
Method of operation
The vehicle is equipped with a high-voltage battery for driving. The high-voltage battery stores the energy needed to operate the elec-tric motor and releases it again.
The electric motor uses energy that has been stored in the high-voltage battery when pull-ing away, accelerating and during the jour-ney.
In overrun mode (except D+), kinetic energy is converted by means of energy recuperation into electrical energy and stored in the high-voltage battery.
The high-voltage battery can be charged as follows:
- through energy recuperation while the vehicle is in motion
- with the charging cable at a mains socket while the vehicle is stationary
- with the charging cable at a charging sta- tion while the vehicle is stationary
The high-voltage battery can be charged in a voltage range from 110 V to 240 V.
If the condition of charge drops to less than 13%, the high-voltage battery reserve indicator lamp lights up in the instrument cluster. Charge the high-voltage battery as soon as possible.
Below a condition of charge of 5%, the performance of the vehicle is reduced. The vehi-cle’s high-voltage electrical system switches off at a condition of charge of 0%.
Use of the pre-entry climate control function may mean that the high-voltage battery is not fully charged.
Discharged battery
The vehicle’s high-voltage electrical system switches off if the high-voltage battery is completely discharged. 30 seconds prior to this, you are informed of the switch-off by the
BatteryBattery level level tootoo low.low. StopStop and and charge-charge immediately message. This protects the battery from exhaustive discharge.
It is not possible to restart the drive system until after charging.
Do not leave the vehicle parked for longer than 14 days with a high-voltage battery condition of charge below 20%.
You can check the condition of charge in the
charge level display (Y page 184).
Further information on the “Energy flow display” can be found in the “Trip” menu (Y page 187).
High and low outside temperatures
Low outside temperatures
The efficiency of the high-voltage battery is significantly reduced at very low outside temperatures. The high-voltage battery is then no longer able to provide the normal electrical power output.
High outside temperatures
To prevent damage to the high-voltage battery due to very high outside temperatures, the maximum power output of the high-voltage battery is reduced automatically.
The E-CELL display indicates the maximum amount of power available (Y page 183).
Energy consumption and range
This range is reduced by:
- high and low outside temperatures
- a non-anticipatory driving style
- switching on consumers, e.g. air-conditioning system or heating.
The battery’s physical characteristics are such that leaving the vehicle parked for an extended period at low outdoor temperatures without charging it can lead to: - a reduction in battery performance
- longer charge times
In extreme cases, this could mean that the vehicle cannot be started. For this reason, connect the charging cable when leaving the vehicle parked for long periods at low outdoor temperatures.
As a result of its basic characteristics, the amount of energy available from the high-voltage battery decreases over the course of its life.
This reduces: - the maximum range that can be achieved by the vehicle
- the maximum output (acceleration) of the vehicle
You can actively reduce the energy consumption of your vehicle in a number of ways, for example, by: - an anticipatory driving style
- reducing the use of electric consumers
- having the vehicle regularly maintained
The charging time of the high-voltage battery may change over the course of its life.
