AI Customer ServiceMuch like heating and cooling the interior of a car, heating and cooling an EV''s battery pack burns energy. As such, expect the overall driving range to suffer somewhat when
AI Customer Service• Terminal Voltage (V) – The voltage between the battery terminals with load applied. Terminal voltage varies with SOC and discharge/charge current. • Open-circuit voltage (V) – The
AI Customer ServiceBYD CTP (Cell to Pack) technology makes the difference, with the Blade Battery increasing space utilization by 50%. This improves energy density and allows more batteries in
AI Customer ServiceThe voltage of a lithium-ion cell is a crucial parameter as it influences the overall voltage of a battery pack when multiple cells are connected in series. When multiple cells are
AI Customer ServiceIn 2019, the average cost of BYD''s new energy passenger car battery pack is 0.85 yuan /Wh. After replacing it with lithium iron phosphate blade battery, the cost is expected to drop by 30%, and the cost is expected to drop
AI Customer ServiceBYD CTP (Cell to Pack) technology makes the difference, with the Blade Battery increasing space utilization by 50%. This improves energy density and allows more batteries in a compact space, with a longer driving
AI Customer ServiceMeanwhile, Shanghai-based NIO is reported to have developed a type of "semi-solid-state" battery pack that can travel 1,070 kilometres on a single charge. China has also
AI Customer ServiceA volt is a potential difference across a conductor when a current of one ampere (Amp) dissipates one watt of power. Voltage is then defined as the pressure that pushes
AI Customer ServiceThe module-free Blade Battery, however, takes advantage of its blade cells to increase the volumetric energy density by up to 50%, suggesting a potential VCTPR and

AI Customer ServiceThe 2021 BYD e-Platform 3.0 brought quite a few changes to the battery pack design. Now with more data available it is worth a more detailed look. BYD make a number of
AI Customer ServiceCut-off voltage is the minimum voltage at which the battery is fully discharged. For lithium-ion batteries, this is often around 3.0 volts. Part 4. Factors affecting battery nominal
AI Customer ServiceThe reported energy density varies between 180 Wh/kg to 190 Wh/kg, which is at least 20% better over the current energy density of 150 Wh/kg. Mated to a fifth-generation
AI Customer ServiceThe total battery pack voltage is determined by the number of cells in series. For example, the total (string) voltage of 6 cells connected in series will be the sum of their individual voltage. The required battery pack total energy E bp [Wh] is
AI Customer ServiceEverbright Securities analyzed the cost of several battery packs made with
AI Customer ServiceGross Capacity—or Total Capacity—is the total amount of energy a pack can theoretically hold. Net Capacity—or Usable Capacity—is the amount of energy the car can actually draw on to move.
AI Customer ServiceMeanwhile, Shanghai-based NIO is reported to have developed a type of "semi-solid-state" battery pack that can travel 1,070 kilometres on a single charge. China has also set up a dedicated fund of six billion yuan (USD
AI Customer ServiceAnyway, the BYD Dolphin and the BYD Yuan Plus were the first electric cars made on the new BYD e-platform 3.0, however the battery packs are not 800-volt. The first BYD electric car to have a 800-volt battery pack will be the upcoming BYD Seal, which will be available with 61,44 and 82,56 kWh batteries.
The BYD Han EV was the first electric vehicle equipped with the BYD Blade battery pack. Image BYD The Blade battery comes with a lithium-ion phosphate (LFP) chemistry as opposed to the usual nickel manganese cobalt (NMC) mix.
With cell-to-pack technology, BYD designed the module-free battery pack using the Blade Cell. The geometry of the Blade Cell is a key to the realization of the module-free battery pack. With the module-free pack design, VCTPR and GCTPR can be enhanced to over 60% and 80%.
Nio had promised to start deliveries of EVs with its 150kWh battery packs in the first half of this year after revising deadlines. And, shock horror, it’s actually happening. The semi-solid-state battery cells are more energy dense than those before it.
BYD make a number of claims around the battery in this design: The platform is likely to be updated to 4.0 in 2024. With the update of the battery pack design and integration the cell orientation has changed.
BYD’s Blade Battery design explored a bold CTP concept through its module-free pack. High quality control in materials and cell manufacturing, however, remain critical prerequisites of CTP. Xinghua Meng is a battery research scientist in the United States.
