From Wikipedia, the free encyclopedia

The Citroën Berlingo Electrique is a battery-powered version of the Berlingo range of vans. It has a 162 V Saft NiCd battery, a 28 kW Leroy Somer motor and has a maximum speed of 95 km/h (59 mph), with a maximum range of 95 km (59 mi) in typical driving. Production of this version stopped in September 2005.

[edit] Overview

As the Citroën Berlingo was designed from the outset as a petrol, diesel and electric powered vehicle, the instrumentation and controls are very similar to a petrol/diesel van.

[edit] Description

[edit] Transmission

The transmission is based on the automatic gearbox concept but limited to Park, Reverse, Neutral and Drive.

[edit] Ignition Operation

The ignition key controls the normal expected functions of accessories, ignition circuit and startng. When the ignition key is momentarily moved to the start position the main traction battery relay is energised (causing a clunk) which allows the accelerator to move the vehicle as normal. The function of the ignition on setting of the ignition switch is slightly different than normal cars because only the stop light and the handbrake light (if the handbrake is applied) are displayed. On other cars all the indicator lights are shown to check bulb condition. This does not give confidence in the indicator effectiveness, but is not a big issue.

[edit] Instrumentation

The large energy meter display shows remaining energy as a percentage and is suprisingly linear. There is some evidence (from certain types of failure cases) that the good linearity is provided by the on board controller monitoring the charge in and out of the batteries rather than the battery voltage. However, the low charge light seems to be operated from the battery voltage. This can mean that the low energy light does not always illuminate at exactly the same percentage charge across different vehicles or even the same vehicle at different times.

[edit] Heating

In order to minimise battery usage, a petrol driven heater is fully integrated to vehicle. It typically takes 5 to 10 minutes to warm and provides excellent cabin heating. It takes several minutes for the heater to run down and will therefore continue to operate after the ignition is turned off.

[edit] Brakes

Power assisted brakes are supplied as standard. However, because the vaccuum supply from the engine in-let manifold that normally supplies the brake servo is not available on an electric vehicle a dedicated vacuum pump is used. (Typical operation of the vacuum pump is on for a 10-15 seconds and off for a couple of minutes).

[edit] Power Steering

Power steering is supplied as standard. However, because the continuous rotation of the engine is not available on an electic vehicle, an electric motor is used to power an power steering hydraulic pump.

[edit] Design Quirks

When the very powerful regenerative braking is active the brake lights are not illuminated. This can be disconcerting for other drivers who may not notice the van slowing significant without the help of the brake lights.

The manual does not indicate that removing the charging plug before it is fully charged can illuminate the 'Electrical Fault Light' and stays on until a full trickle charge is performed. This can be quite disconcerting as the manual says you have to take it to the dealer to reset the problem. Also, you cannot, or should not, perform a fast charge when it is in this state.

[edit] Miles Per Charge

The actual maximum miles per charge is very dependent on the driving style. Specifically the speed. This is because atmospheric drag is non-linear with speed. i.e. increasing the speed by 25% will decrease the range by 36%. To get the most range for any electric vehicle (and to some extent petrol/diesel vehicles) involves driving at the slowest practical speed.

Typical ranges are as follows.

Speed
(mph)		 Miles Per
Charge		 Source

  • As with any vehicle driving in the heavy rain increases rolling resistance and therefore decreases the miles-per-gallon for petrol/diesel and reduces the miles-per-charge for electric vehicles. Typically reduction is about 15% .

[edit] Availability

The Electrique was made available in at least the following countries.

  • United Kingdom

[edit] Servicing

The Electrique is a simple vehicle with minimal servicing requirements. Details of servicing information is available at Citreon Berlingo Electrique Service Manual

[edit] Common DIY Enhancements

The basic Electrique does not come with rear seats or windows. It is common for owners to install a compatible (Multispace) rear seat and rear windows.
