More images are now available of the 2026 Tesla Semi Battery and hence we thought we should create an update from the original 2022 Tesla Semi Specifications. Spec Standard Range Long Range Range ~325 mi ~500 mi Energy Consumption 1.7 kWh/mi 1.7 kWh/mi Fast Charging Up to 60% in 30m Up to 60% in 30m … Read more
The conventional framing of carbon black in lithium-ion battery electrodes is electrochemical – it is an electronic conducting agent that enables the formation of the electrical wiring within an electrode. It has typically been specified by loading, surface area and subsequent powder or electrode resistivity. For wet slurry coating, this framing is broadly adequate. The … Read more
The Tesla 4680 Cell Generation 2 is interesting as this has been in the battery and electric vehicle news so much. We originally looked at the Tesla 4680 cell back in November 2022, since then lots of progress and once again The Limiting Factor have done a teardown. The “roses” that collect the edges of … Read more
CATL BTF0 161Ah LFP is the cell used in the 55kWh Tesla Model 3 SR pack. Sandro Stock et al [1] have published a cell teardown and analysis. This gives an insight to the cell characteristics and design. The cell is made by CATL. Spcifications Jan Schöberl et [4] Metrics It has two jelly rolls, … Read more
The Munro Live Youtube channel tore down a Cybertruck vehicle below are some insights and highlights for the vehicle’s battery pack. The Cybertruck battery pack uses Tesla’s 2nd generation 4680 form factor cells and the battery pack also is a structural element of the vehicle. The seats are directly attached to the battery pack which … Read more
The Tesla Cybertruck Battery is an interesting design as a lot of elements are developed from the 4680 based Model Y. In the previous post we looked at the battery to body structure around the Cybertruck. Note: huge thanks to Munro Live and their teardowns, checkout their channel and references below to see more. The … Read more
The Tesla Self-Activated Draining System was patented some time ago, but this simple mechanical device is still being used in the latest Cybertruck. A method of managing leakage of liquid inside a battery system comprises: containing leaking liquid in a non-liquid sensitive region of the battery system so as to protect internal electrical components of … Read more
Battery thermal management (BTMS) systems are of several types. BTMS with evolution of EV battery technology becomes a critical system. Earlier battery systems were just reliant on passive cooling. Now with increased size (kWh capacity), Voltage (V), Ampere (amps) in proportion to increased range requirements make the battery thermal management system a key part of … Read more
Auxiliary systems power consumption in a vehicle especially an electric vehicle have a big effect on the vehicle range. The Range is decided by the battery capacity in kWh. Battery capacity is primarily used to provide traction power through AC or DC motor. Efficiency of motor, drivetrain and battery can tell you how much power … Read more
The Tesla LFP Model 3 is quite a landmark battery pack for Tesla. Up until now everything has revolved around chasing the energy density of cylindrical cells from 18650 to 21700. The 4680 cylindrical is a move to a larger and lower cost cell. This move to Lithium Iron Phosphate (LFP) is perhaps more significant … Read more
