" In 2003, we produced an
advertising film [watch opposite], unfortunately never released, to
promote the Kangoo
Elect'Road, the upgraded version with a gasoline range extender from
the model Electri'Cité ", recalls
the retired technician . The movie featured a young couple traveling to
Lugano, Switzerland, from the Paris region.
-----------------------------------------------------------------«
I got the chance to
meet the leaders of the SVE Company
(Systèmes
de Véhicules
Electriques
- created by Dassault-Heuliez) who were foreseeing to bring on the
market upgraded electric Kangoo, with a canadian powertrain which was
allowing them to reach a range of 250 km thanks to a SAFT Lithium
batterie », « Before to vanish,
the service had already achieved a prototype with these same
lithium-ion batteries. It offered a range of 170 kilometers, and was equipped with a new
thermal range extender

unfulfilled. To see also about this topic : 15/05/2017

Sycomoreen is indeed working on a new special prototype of car with renewable energy, more information on the right picture |
CATHI succeeds in its technical check with the expected performances by the usual requirements of the automotive safety.
Multilinguage script of the movie.After more than 65 000 km, the differences of braking and suspension are weak and the distribution of the mass is 55% at the front axle 55% (905 kg) and 45% (750 kg) at the rear axle for a total mass of 1655 kg (driver is taken in account). The Car Actuated by Triple Hybrid Integration (CATHI) is an exclusive intellectual property of SYCOMOREEN. To see also : 06/11/2014 |
Contrôle technique / Technical check of CATHI by Sycomoreen |
After the CATHI's restoration of the Nicad Pack, and the mounting of tires with low rolling résistance, SYCOMOREEN has improved too the balancing of its 2 Lithium Iron Phosphate packs. On a trip with 800 m of vertical drop (driven up, then down ), here are the results ! | 100 driven kilometers with 20 km of range remaining, nevertheless the load of the Nicad pack was not an equalization (which can give 10 additional km). Thus it appears a Maximal Range of 130 km, although this vehicle got only 80 km out of its manufacture ; either + 60% ! And this without to use the electrogenerator... |
CATHI has been offered a set of well adapted tires for an electric vehicle : its 4 rims Tornado Silver 14" from the brand Cesam Sport, and also 4 tires
Michelin Energy Saver 175/65 R14 82T. These 4 wheels with lower mass and "green" tires are going to improve the consumption of the
vehicle.

The Berlingomoreen CATHI has removed
16 batteries from its Nickel
Cadmium pack of 2003 for more reliable 2011's models which
are offering a better storage. The
previous batteries are still useful and have been given to
several fans of solar energy who will benefit from them to store renewable electricity.
A full technical
check has been lead, with the change of the direct voltage
engine's brushes, and the new start of the Webasto's
gasoline burner which is not at all reducing the range of the vehicle
by using yearly less than 10L of ethanol/gasoline, whereas
the
recent electric vehicles which are exhausting their
batteries to heat the cockpit or unfroze the windshield... CATHI still takes advantage
from its
valiant current pushers Lithium-Iron-Phosphat which are
upgrading the range at 120 km with a full electric drive, and will
improve the mounting of its electrogenerator...
which his bringing an
even higher reachable distance and more of serenity for
the long unforeseen journeys...
Thanks to the investment of the
materials, energies and talents of différent actors of PSA Nicad's EV,
the CATHI's adventures are therefore far to be over ! SYCOMOREEN offers you the
opportunity to dive in the heart of this unique vehicule

CATHI
succeeds in its technical check with greater performances
than the usual requirements of the automotive security.
The differences of braking and suspension are minute and the
distribution of the mass is 55% at the front axle 55% (854 kg) and 45%
(713 kg) at the rear axle for a total mass of 1567 kg (driver is taken
in account, not the electrogenerator).

The technical check of CATHI by Sycomoreen |
At the end of
every charge, the Nicad accumulators consume some water which is
converted into H2 and O2. That's
why one has to refill the batteries with demineralized water.
This operation is done every 4000 km on the CATHI van.
Note : the hydrolysis of water is strongly protecting the Nicad batteries because it prevents them from any damage by overcharge. |

The campaign of consumption

of the Berlingomoreen CATHI is still in progress with its 4000th kWh for a driven distance of
17 479 km, either 12% less than the initial needs of the
Citroën Berlingo Nickel Cadmium (26
kWh/100km), in
spite of the carried additional mass of 8 kWh of LiFePO4 batteries.
This electromobility is 100% renewable thanks to the OPALE solar plants. |
The
Y4000 SAGEM Box, real managing brain of
the PSA Nicad electric cars
The existing platform of the electric
Citroën Berlingo is equipped with an Y4000 SAGEM
box. It includes a PWM
source/receiver of power reversible for the current : it
allows to launch the vehicle or to have
a regenerative braking. There is also a calculator, true manager for all
the parameters and piloting the PWM device. Moreover, the
Y4000 SAGEM box gets 2 converters ; the
3000W loader 220VAC/160VDC
for the Nicad pack and the auxiliary
loader 160VDC/12VDC for the accessories and the 12V lead
acid battery.
In
addition, the
LiFePO4 packs installed by Sycomoreen have their own
managing electronics and are designed to
bring a constant current into the Nicad batteries, without interfering
with the SAGEM box
whatever the voltage of the Nicad Pack is. They are including their
specific loaders and Batteries Managing Systems (BMS) to balance the
Lithium elements. If it is required, they can be supplied by 2300
W AC220V coming from an electrogenerator
(to see also : the CATHI's
architecture).

Test of CATHI's electric autonomy
under hard wintry conditions Topology 75 km round-trip 750 m of driven altitude up and down Climate and driving condition Snow coverage : 0 to 10 cm and temperature 0°C Road of mountain Performances Average speed : 45 km/h After the start at exactly 100% (no overcharge) in every pack of batteries, the arrival gives: - 24% remaining in the Nicad pack, - 28% remaining in the first LiFePO4 pack, - 20% remaining in the second LiFePO4 pack. Conclusion Either about 1km per %. In these unfavorable conditions, the maximal CATHI's autonomy is around 100 km ; 20% less than the usual range. |

This Berlingomoreen gets 3
different sources of energy (triple
hybridization) 1) one pack of NiCd batteries (Nickel Cadmium : 16.2 kWh) 2) one double pack LiFePO4 batteries (Lithium Iron Phosphate : 4 + 4 = 8kWh) 3) one thermal electrogenerator of 3000 W peak which is started especially The initial architecture of the vehicle and its management are protected : some additional direct current (30A under 162V) is injected through the PWM with the 2 breakers of the control panel. While circulating, the driver is free : a) to turn off the range extenders if the conditions of circulation don't need them (cities, coming down) b) to turn on the range extenders if power is required (road, freeway, coming up, overtaking) For the reload, 2 options are possible : 1) Electric reload on the grid with 220V 50Hz plug, according to 3 variants : a) pack NiCd only through the Maréchal plug with the K1 breaker closed and K2 opened (14A 220V AC) b) packs LiFePO4 only by closing the K0, K5 and K6 breakers (it needs for 11A 220V AC) c) all the packs with the Maréchal plug with K1, K2,K5, K6 ON. K0 stays OFF and. : i) K3 is OFF during the 9 first hours (14A 220V AC), ii) K3 is ON as soon as the start of the 10th hour (11A 220V AC) 2) Thermal reload with the electrogenerator : K4,K5 and K6 are closed, K0, K1, K2 and K3 are opened. This reload flows through the LiFePO4, but can also directly go towards the NiCd through the loaders + overvoltaging converters of each range extender. |
