Specifications: The 2021 Mercedes EQA 250 is an all electric compact SUV. Traditional layout with a single motor driving the front wheels and a battery pack under the passenger compartment. Peak discharge power is estimated based on peak motor power of 140kW and a motor and inverter efficiency of 90%, hence 140kW / 90% = … Read more
The 2016 Renault Zoe ZE 40 was the first battery upgrade for the Renault Zoe. Specifications: total energy = 45.3kWh The total energy versus cell temperature. The capacity is quite consistent down to a cell temperature of ~5°C. Below this temperature the total energy decreases dramatically. usable energy = 41kWh Usable SoC = 90% peak … Read more
The Renault Zoe is a supermini electric vehicle. Since 2013, the Zoe has been the all-time top selling all-electric car in the French market, with more than 100,000 units registered through June 2020 [1]. 2012 Renault Zoe ZE Usable energy = 22kWh (25.92kWh total) Configuration = 96s2p Cell = 36Ah Pack weight = 280kg 2016 … Read more
The BYD Blade pack design is the first cell to pack design that encompasses everything this means. Not having a module and the overhead of a module is difficult to achieve. LFP cells make this design easier in some ways and this gives a new lease of life for LFP chemistry. The Tesla with CATL’s … Read more
The GM Ultium is a flexible battery pack architecture destined for a number of vehicles. GM is planning on building 1 million EV’s a year by 2025 and hence has invested in a joint venture with LG Chem to produce the Ultium Cell. Ultium Cell At the moment the details around the cell are limited … Read more
The iconic electric vehicle the 2010 Nissan Leaf was launched in December 2010. The world’s first mass-produced full sized electric family car. Specifications: total energy = 24kWh usable energy = 22kWh Usable SoC = 94% peak discharge power = 90kW10s (based on 80kW motor peak power) peak charging power = 46kW discharge pack resistance = 0.138 … Read more
Nissan increased the battery capacity from 24kWh to 30kWh with a change in cell supplier. An increase in cell energy and moving from a 4 cell module to an 8 cell module allowed this energy to be contained in the existing case. This meant the overall battery package was the same shape with an ~21kg … Read more
The Nissan Leaf is perhaps the iconic original OEM BEV. Therefore, interesting to see how it performs against the competition over the years. The pack gravimetric density versus year of introduction is an interesting plot. Arguably the energy density should be outstanding as these packs are passively cooled. However, they are also conservative with respect … Read more
The 2019 Porsche Taycan comes with a total/gross 79.2kWh or 93.4kWh battery pack Turbo S Performance Battery Plus This is the largest battery capacity on offer in 2019 and the highest power. Specifications: total energy = 93.4kWh usable energy = 83.7kWh Usable SoC = 90% peak discharge power 460kW10s continuous power = 270kW The 270kW … Read more
