Nominal Capacity: 65,6 Ah (discharged at 21,6 A) - 64,8 Ah (discharged at 32,5 A) Minimum Capacity: 64,6 Ah (discharged at 21,6 A) - 63,8 Ah (discharged at 32,5 A) Nominal Voltage: 3,6 V Charging Voltage: 4,2 V Thickness: 11,5 mm Width: 125 mm Height: 325 mm Volume: 0,4671875 L Weight: 964,9 g Volumetric Energy Density: 492-505 Wh/L Gravimetric Energy Density: 238-245 Wh/kg Renault ZE 40 battery pack (192 cells in 96s2p configuration)
LION Smart shows off a BMW i3 with a 100 kWh battery
LION Smart shows off a BMW i3 with a 100 kWh battery
Less than 2 years ago, LION Smart showed us a BMW i3 with a 55 kWh battery, now it gets upgraded to 100 kWh with 700 km of range. Made with a total of 8.064 cylindrical battery cells (18650 format) the battery pack has a maximum voltage of 400 V and a capacity of 101 kWh (see the video). At the pack level the battery has a very impressive volumetric energy density of 460 Wh/L and a gravimetric energy density of 230 Wh/kg, this is very similar to what the Nissan Leaf 40 kWh battery achieves at the cell level.
CATL expects to introduce NCM 811 battery cells next year
CATL expects to introduce NCM 811 battery cells next year
The low-cobalt content and high energy density NCM 811 battery cells for electric cars were expected to be introduced this year by the South Korean battery cell makers LG Chem and SK Innovation. Unfortunately, a few months after the initial announcements these plans were postponed. Now the Chinese battery cell makers will try to introduce the NCM 811 cathode technology first to gain competitive advantage. Not only BYD is aiming to introduce the NCM 811 battery cells for EVs next year, CATL has also the same goal.
Range and efficiency test of 10 electric cars
Range and efficiency test of 10 electric cars
The staff of coches.net and AUTOBEST tested the range and efficiency of 10 different electric cars. On the first day the cars were tested by the staff of the coches.net (test 1) and on the second day the cars were tested by the AUTOBEST’s staff (test 2). All electric cars were driven until stop from empty battery. The tests were conducted around Barcelona in highway and city traffic. All electric cars were set to normal mode (no eco or sport modes) and with AC on (set to 19-23 ºC). The outside temperature varied between 26 and 33 ºC, perfect to get high mileage.
New LG Chem on-board chargers up to 11 kW
New LG Chem on-board chargers up to 11 kW
LG Chem offers complete and easy solutions for automakers that want to electrify their cars. The company not only produces batteries for electric cars, but also motors, inverters and now on-board chargers. In Europe, 3-phase on-board chargers will soon become standard and LG Chem acknowledges it by making the 11 kW variant available from the start. While it’s a shame that a compact 22 kW variant isn’t already available, there’s always the possibility of using two 11 kW chargers in parallel to reach 22 kW.
Samsung SDI presents new high-capacity battery cell
Samsung SDI presents new high-capacity battery cell
Samsung SDI was present at Energy Storage Europe 2018, Germany’s ESS Exhibition and revealed a new high-capacity battery cell. The 111Ah ESS battery cell showcased by Samsung SDI at the conference has the feature of substantially increased capacity. The capacity of this ESS battery is enhanced while the size is maintained through material innovation, and thus significantly increased the energy density of the battery. Moreover, the strength of this battery is that it allows an easy product upgrade without having to modify its design.
Fast charging curves
Fast charging curves
Fastned made some useful tests to show how different electric cars handle fast charging. This is particularly important for those who plan to use fast chargers regularly. Let’s see the results. Nissan Leaf 24 kWh edition: fast charging until 25%, charging will gradually go slower after this 30 kWh edition: fast charging until 80%, charging will go slower after this 40 kWh edition: fast charging until 60%, charging will go slower after this BMW i3
Most advanced battery cells available
Most advanced battery cells available
In this article we’ll see who is using the most advanced battery chemistries and what’s coming soon. Currently, most important advancements are being made at the cathode level, by increasing the nickel while reducing the cobalt content it’s possible to get cheaper and higher density battery cells. LG Chem Interview with LG Chem CFO Chung Ho-Young (translated by Google): Q) This is a question about medium and large batteries. I am wondering how the NCM811 next generation battery development is proceeding. A) Batteries using NCM 811 cathode materials are mass-produced for electric buses. Third-generation batteries are a major direction of development to increase energy density, reduce cost, and improve charging performance. For this purpose, the nickel content is basically increased, the specific gravity of cobalt is reduced from the viewpoint of cost, and the artificial graphite is applied for rapid charging.
Battery charging: Full versus Partial
Battery charging: Full versus Partial
Batteries are part of our lives. They are present in everyday devices such as electric cars, smartphones, tablets or laptops. For this reason it’s important to know how to treat them right. We already know that TMS (Thermal Management Systems) are important to keep batteries at recommended temperatures, but what about charging behavior? What can we do to reduce battery capacity degradation? Is it better to cycle batteries with partial or full charges? And at lower or higher SoC (State-of-Charge)?

Be warned, this is going to be a long article. Nonetheless if you’re interested in battery technology or have a BMW i3, you’ll like reading it. Later this year, the BMW i3 will get its battery upgraded with NCM 622 cells and the capacity will increase from 94 to 120 Ah. With 120 Ah battery cells, the BMW i3 will have a total battery capacity around 42,62 kWh (96 x 120 Ah x 3,7 V).
NCM 811: SK Innovation vs. LG Chem
NCM 811: SK Innovation vs. LG Chem
There are two major battery cell makers that promised NCM 811 EV battery cells for 2018. They are SK Innovation and LG Chem. Let’s recapture what we already know about it. As you already know, currently most EV batteries have NCM 622 cathodes, which means that besides lithium the cathode contains nickel, cobalt and manganese in a composition ratio of 6:2:2.
Nissan Leaf battery degradation data: 24 vs. 30 kWh batteries
Nissan Leaf battery degradation data: 24 vs. 30 kWh batteries
In a recent study 283 Nissan Leafs manufactured between 2011 and 2017, had their SoH (State of Health) measured 1.382 times. The data is from 82 Nissan Leafs with 30 kWh batteries and 201 with the 24 kWh variants. The measurements were made by using a OBD2 scanner with the Leaf Spy app. The study has some interesting conclusions and I recommend you to read it (only 14 pages), but in this article I’ll focus on one:
