from chemistry to pack
CATL and Quibo’s Mobile Power Plant Ultra 2.0 packs up to 2,036 kWh, a converter, EV chargers and a solar inverter into a 20-foot container. What the IAA 2026 placard discloses, what it leaves out, and how it compares.
The Battery Data Behind IAA Transportation 2026 IAA Transportation 2026 ran in Hannover from 15 to 20 September, and electrification was the theme running through most of the exhibitor announcements: Volvo, DAF, MAN, Scania and SANY all had electric truck news on the stand. The one battery-specific launch worth digging into in detail is CATL’s … Read more
A phone battery looks like a simple, sealed slab. Underneath that, five engineering problems are being fought at once, and each one constrains the others: what the electrodes are made of, how fast heat can be pulled out of a space the size of a credit card, how the charging circuit routes power without wasting … Read more
My first new car (ever) is an EV Renault Megane E-Tech Techno 220cp 60 kWh. EV Details: My Experience Total km till Date: 573 km. I only did few trips near the house before one long trip (details below). I have solar panels at home so I am charging Type 1 with maximum 2.3 kW … Read more
The Renault 5 E-Tech has two battery packs defined by usable energy of 40kWh and 52kWh. Initially the vehicle is launched with the 52kWh usable pack. This pack is assembled by Ampere, a subsidiary of Renault and using AESC pouch cells. This post has been built based on the support of and sponsorship from: Quarto Technical Services, Eatron … Read more
The Non-Linear Voltammetry (NLV) charging method differs from Constant Current (CC) based charging methods in that no CC is applied at any time. Instead, a series of short Constant Voltage (CV) steps are applied, separated with very short rest periods while monitoring the current response and temperature. A transition from one CV plateau to the … Read more
BYD have stated “Oil and electricity at the same speed”, by this I read: Charging at the Speed of a Petrol Pump. What does that mean in terms of power? A petrol pump delivers 30 to 40 litres/minute energy content of petrol = 9700 Wh/litre 9700 x 40 = 388,000 Wh/minute = 23.28 MWh/hour = … Read more
Constant Current – Constant Voltage Charging (CC-CV) is where a battery cell is charged at a constant current until it reaches the maximum charging voltage at which point the voltage is fixed and the current reduced. The following graph shows this relationship versus charge time. The constant current charging up to 4.2V is at 0.5C … Read more
Charging Current Control Strategy Based on Online Evaluation of the Chargeability Status of its Cells Authors: DIAB Raymonda, SCHAEFFER Emmanuel, AUGER François, POIZOT Philippe, COUSSEAU Jean-François Context Charging time reduction allows : Challenges Standard fast charging methods of Li-ion batteries : Methodology This algorithm enhances the charging current in order to maintain the observed overpotential … Read more
While individual battery cells can charge in under 15 minutes, EV battery packs take much longer to fully charge. There are a number of factors that influence that, including temperature spread across the pack. Key Factors Limiting Battery Cell Lifetime During Charging At the cell level, the fastest rate at which a battery cell can … Read more
